Flex 6xxx Fan Replacement

There has been great concern about fan failure and replacement in the fgpa fan speed thread.  That thread has gotten almost impossibly long and difficult to follow.  

The concern of late has been about acquiring fans and DIY replacement.  K2CB has been kind enough acquire fans at a favorable price so acquisition is not a problem.  Replacement is the next hurdle.

 The concern expressed by Flex re DIY fan replacement is the concern about damaging the chip due to the fact that the adhesive is so STRONG.
The other concern expressed by Steve is difficulty replacing the shroud.  It doesn't look too difficult so long as you are extremely careful getting all the tabs aligned properly.

I hope someone (Flex?) will post detailed instructions.  Meanwhile my  4 year old 6500 has been been cruising along with no problems but, in an abundance of caution I have ordered 2 spares.

Hopefully,  Steve will post a failure rate of these fans so we will have an idea how real the concern about fan failure really is.

Gene and all,

I have done the fan replacement recently (I posted original fan pics). They are not at all difficult to change, you should leave the heatsink in place (no need to disturb the heatsink bonding anyway).

Carefully unscrew the fan subassembly from the heatsink whilst holding the heatsink so that it does not try to rotate, then place the new donor fan to the existing heatsink. Check they spin-up okay, and the radio boots happily with the new fans - job done.

The RF cage is pretty large, but NOT difficult to get back on. It has lots of friction grip fingers, and is hampered some by less than idea positioning of it close to the outer case, but it can be done.

The whole job takes about 30 mins and is easy to do - provided you have good eyes and a steady hand. However, it should only be attempted by those that understand which end of a soldering iron gets hot (!) i.e. if you already do component level work then this is a walk in the park. Not sure why Flex make out its such a big deal really.

The only bad thing is that Flex have failed to take a positive lead with good service - especially when the fan are failing so prematurely. The user base has had to ID the problem, find the part code, find a source, and order parts for themselves. A sad reflection on Flex IMHO.

Thank you very much - that is exactly what I was looking for.  Now if Flex will only publish a realistic failure rate.

Considering that this might very well have been a bad batch of fans, it would be pretty difficult to come up with a realistic failure rate for everyone.

Thanks.  I'd be happy to do my own fan replacement to my 6500 if it needed it...it sounds like you've found a UK supplier.  I feel like I should buy a fan and it keep it just in case.  Please could you let me know how you got yours?  Regards  Paul M0CVX

p.s.  I'm in Lincoln...so not far away from you I guess...

I would like to add my final thoughts on this cooling fan issue.


So clearly these fan’s are a big problem, Now obviously all moving parts like fans will eventually wear out unfortunately these are failing way too rapidly. I’m sure when the engineers at flex decided to use these fans in the radio design they expected them to last a lot longer than they have something they could not have anticipated since the fans are rated by the manufacturer for a minimum of 50,000 hours before failure.

Now add the fact that the manufacturer of the fans have decided to basically discontinue these fans, thankfully there is a reasonable amount of stock still out there to last for a little while so it’s not that desperate just yet. And better than that, some of the users have gotten together and are ordering direct from the manufacturer in bulk while supplies last to get ahead of the depleting part stock.

The problem is that awesome radios like the 63/65/6700 up to a $7500 radio are potentially being “Bricked” over a $15 part.

IMHO the flaw in the design is relying too much on moving parts like these fan’s, something FRS has learned from and that's why the new 64/6600(M) don't have these fans. Keep in mind that these radios are touted as “Radio Servers” and that now with SmartLink more than ever many users will want to leave on 24/7 to take advantage of the new powerful remote capability.


Where do we go from here?

The primary cooling fans in the radio is a pair of Standard 12vdc PC type 80mm fans that are easy to obtain. However the ones that cool the FPGA and main CPU are very specialized and now hard to get.

So as I have mentioned before I think the best way forward is to design a passive cooling option using a large Heatsink, plus you get the added benefit of reduced dust witch lowers the about of times the user needs to open these radios to clean the insides. Now I know it’s easy for me to sit here and Monday morning quarterback the engineers at FRS but I think this is going to be the best way forward.


The engineering questions to be addressed are as follows:

1. Can a large enough Heatsink be make to safely “passively” cool these chips with a reasonable temperate margin or headroom?

2. Can it be made to fit inside the existing RF cage or will a new cage have to be made?

3. Will this large Heatsink create RF issues inside the cage, such as parasitic’s causing the radio to crash or damage the chips?

4. Can the R&D and part be made at a reasonable cost?

I’m sure I missed some other possible issues but these are some of the basic questions.


Here is another question,

What happens if nothing is done to address this issue, I think this could be a disaster for Flex and it’s reputation. Imagine as more and more of these fan failures continue to pop up over time what this could do to FRS reputation and the confidence that people have in their products. Also how ticked off people that have invested thousands of dollars in these radios find that they are unusable is such a relatively short time after purchase. Just imagine the reviews on EHam, QRZ, YouTube and other websites in the ham radio community. All this while the SDR radio continues grow and to be made by other companies with deeper pockets. This is just the kind of thing the competitors would just love to use against Flex.

I have a good feeling that Flex already knows all of this and will fix this issue, restore confidence with it’s valuable customers and avoid a potential Public relations nightmare.

We’ll just have to wait and see.

Where can I order the fans for 6500?  I have had one tach error on my 6500 and would rather have the fans available.

John, many things stated here just are not true, The radio is not in danger of being bricked as you claim. Steve said they still have a good supply of fans in stock, and he said the engineers are looking into other options for cooling, there is no one on the community that knows as much about this then the Flex team, so stop pretending we do.

Steve said they have had meetings on this and they are looking into why some fans fail and others run for years.

I understand there have been some fan failures but blowing this out of proportion is not helpful.

@ Gene
You are part of a very small group who feel Flex has failed in it's servicing in this respect.
Steve explained why he has taken as long replying to all the questions here.

Guys, if we are going to call Flex out over this, then we should keep our comments fair and factual.
I am still not sure going on our own is the best thing and not working with Flex to find a better ground. Steve and the team have been very busy as he said and Flex does not see this as a pressing problem as yet,,so there is no panic. But we should give Flex a chance to work on this and let them report what they find out and are willing to do.

Well said,,I am not at war with John, and I am not trying to diminish the fan problem,,it is real. But it is being investigated and it may take some time for Flex to come up with a plan. I am willing to see what they find out.
It was interesting Steve did say there is a clear difference between the early fans compared to the latest ones for failures. So they know that.. and they are not happy with the fans issue.


Many times some on the community state that I work for Flex, or have inside secret information. This is not the case at all. Much of the replies from Tim or Steve or anyone on the Flex team seems to go over some peoples heads. Or chose to ignore it.

All I simply do is re- post their replies to confirm the reply, see, I have no inside info, It's all there in the answers. Read them!!

I am sad that someone has stated that Steve at Flex is not telling the truth about fan supplies in stock,,and wanting him to prove it. It was Steve that said that not me, I just re stated his comment, if he said they have stock and there is no need for emergency measures on the fans, that's ok with me.

Anyways, I think I have made my comments clear, time to go onto other more productive things.

I would like to say Flex has been good by me and my 6500, yes it's still under warranty and I have had I think 4 or 5 fan failures, am I mad? no. In one case after sending my radio back for the 2nd time or 3rd time I don't recall but they shipped a new unit.
I just had my 4th fan failure and got the radio back 2 weeks ago. I can tell you the only way I can tell if the fan failed was when the radio was turned off, I leave the radio running 24/7. It's kinda like hard drives on a server, you never want to turn off a server! In the end, I'm a happy Flex customer. Flex you can now send me that 2.0 upgrade to my address on file! jk!

Cheers all

I think you've been very patient, Rory.  If I'd had '4 or 5' fan failures on my 6500 I'd be livid.  I'm still mulling over how to interpret your post, but it certainly isn't reassuring!  Fingers crossed that your current set-up continues to work well.  Regards  Paul M0CVX

Hello Paul, what good would it do to get all bent out of shape over this? It's just a hobby and if I thought this was that important I would of bought a second or third radio beside I have a few boat anchors I can fire up. Now if my name was Craig K3CT and running a contest station I had already planned for these contingencies. So bottom line is life is to short to get bent out of shape over the little things. 73

In Austin, Texas right now, we have been told by officials that there is no gasoline shortage.  My car was at 7/8 full yesterday and I didn't think twice as I passed several stations with long lines.  As a result of everyone discussing the "gas shortage" many people have run into the streets to fill their cars and large containers with gasoline.  I saw one picture yesterday of someone filling a huge trashcan with gasoline.  I bet you can guess what I think of that.   The average gas gauge reading in Austin is probably the highest it has ever been.  With the panic now firmly in place, many stations around Austin are without gasoline.  As a person with an education, I looked at the numbers on refineries that were down, where the gas comes from and the percentages and I decided that I was not concerned.  Certainly not "fill a trashcan with gas" concerned.  No doubt, the people that staged a run on the gasoline stations are saying "I told you so" -- and they probably believe they are right and they feel justified.

There's an old movie with Robert Redford, Sneakers, where the antagonist makes the comment that mentioning publicly that a bank is unstable causes a run on the bank and the run on the bank causes it to be unstable -- even if it was fine to start with.  Panic begets panic.

Yes, some of the fans are failing earlier than we expected.  We believe something that has changed with the supplier as the early fans we purchased are having significantly fewer problems that newer fans.  We had an internal discussion about fans long before anyone pointed out publicly that there have been fan failures.  We are investigating and working toward a solution.  Our ME passed away suddenly this year and we have someone to help us now, but we had a backlog of work for him and this hasn't been addressed yet.  We will formulate a solution and we will communicate about it when we have it.  

We (FlexRadio) will continue to charge some of the lowest service rates in the industry, treat our customers fairly and do all we can to help them.  As we have time, we will continue to answer well-intentioned, sincere questions from you guys -- our loyal customers -- on anything that is of interest to you that remotely concerns our products or ham radio.  I appreciate that some of you are concerned because of a component failure.  Please believe we're doing all we can to get to the crux of the problem and come up with a solution, but continuing to suggest that we might not do something about it (and what a disaster that would be for FlexRadio) just isn't helping.  Someone suggested that we are not "providing facts" on actual MTBF of the fans.  As an engineer, if I'm asked to report MTBF you sorta have to know the time that the fans are running. We do not collect information from our customers on how many hours a day their radios are turned on, hence the calculation is difficult.  It helps no-one for me to get into a pedantic discussion about calculation of MTBF.  It also really doesn't matter -- MTBF is a decision support tool.  We've already made the decision that we are not pleased with the fan performance and want a replacement solution.  Why would I painstakingly calculate MTBF now?  All the answer I need as a businessman is "the reliability has decreased with the newer fans and we would like a replacement solution."  Please give us the time to develop a solution.  And don't panic.

Question about the cage replacement process.

Is there a test or procedure to verify whether the cage has been replaced correctly?  Certainly if you are getting lockups from RF that would be a clue since it's purpose is to keep RF from the receiver.

Would there be any benefit in looking at before and after snapshots of the panadapter to see if there is any significant change in the transmit signature? 

Does the FRS service team have anything they can share?  I wouldn't be surprised if it is just a re-install carefully and visual check but it doesn't hurt to ask.

You have it backwards, Al. The receiver is *outside* the cage. The faraday cage's purpose is to keep high-speed microprocessor, Ethernet, DDR3 memory, etc. noise from reaching the receiver. In other words, it keeps bad stuff inside, rather than keeping RF outside.

Steve,
Thanks for the correction. We usually think about using a faraday cage to keep rf from getting in but I get it now. So it sounds like rather than a concern about RF causing a lockup, it would be noise getting into the receiver.

I guess the basic question is still valid. Is there any specific test or observation to insure it is reinstalled and working correctly? In other words, is there something you can see on the panadapter like a change in the noise floor or noise spikes? Or is the reinstall verification process just a visual check of the cage to insure it is installed correctly?

Thanks, if I ever need to remove and install the cage for a fan swap, I'll make a short video of the panadapter (using a dummy load antenna) first for comparison.

Speaking of the shielding cage, if anyone has any photos of the opened cage, original fan, and actual pin connector where it plugs into the board, I would greatly appreciate an email with a photo or two.  I want to be 110% sure the mfg is supplying me with the correct connector and lead length, so it is truly a plug and play swap.  They have asked me for a photo of the original unit and connector so as to verify.


Also, with the photos, I could possibly photo shop them and prepare some sort of how-to doc to enclose with the fans when they ship.


BTW, we have met the minimum, but there is still time to get on the list, as I can increase the quantity if needed.


Thanks,

Eric

On an sd card??

I assume that the two picture shown above are of the fans that all the discussion has been about over the last week or so.  I have not seen the fans or the RF shield my self but if my assumption is correct,   I think that if one was to get a small syringe filled with very fine machine oil.  Poke  the needle through the shield  and through the label on the fan (just off center) the inject a very small amount of oil into the fan bearing.  This would extend the life of the fans.  I have done this to many computer fans and it quietened down the fans and they start running at full speed again.
If my assumptions are wrong please ignore all above.

Just noticed the SD card as well. I'm nervous running a Pi 24/7 on an SD card because, well, SD cards aren't meant for the constant read/write operations that a computer executes to it's boot storage device. As a result, I have backup images made and spare SD cards on hand for a quick fix should the card fail. 

Anyone here know more about this? I have to replace the FPGA fan on my 6300, so I have to pop the top anyway. Is it worth making an image of the SD card so that I can avoid a trip to Austin should the card fail in the future? Is an SD card failure rate even something I should be concerned with?

It's not a typical MLC or TLC SD card.  It is an SLC industrial card that has 10x the endurance/lifetime of what consumers buy.  We also optimize when we write to the card in software, avoiding repetitive writes to the card.  There are other software related hazards that can occur when changing the card.  My recommendation is to avoid removing it (a subtle way of saying it may not behave as you expect if you swap the card).

The TOTAL number of FANS varies by 6xxx model per the "help desk."  See snapshot below about the fan cleaning process. 

But all models have 2 fans inside the cage which are the ones Eric / K2CB is offering. One for the CPU and one for the FPGA.   I ordered 2 and figured if I have to remove the cage to replace one, might as well replace them both.   (although the only error I've seen reported is the FPGA error so wonder if there is a CPU error as well or do both get reported as the same FPGA error)

 


@Eric, what about replacements for the other fans?   Should there also be a supply of the other one (1) or two (2) main cooling fans at the front of the chassis?   Assume they are a different model, is that correct?

I haven't seen much about the failure rate for them or whether they generate any specific error codes.   But in a few posts there have been references like  "FRS replaced all 4 of my fans."

Michael,
Thanks I did find an example of  the CPU Fan speed error.  (guess that maybe the FPGA error is more common?) 




I haven't seen the fan / temp errors all listed in one place but it appears there are 3 different errors depending on the fan location.   

CPU Fan Speed - (fan in the cage)
FPGA Fan Speed (fan in the cage)
Overtemp error - for the fan or fans near the front panel outside the cage

I didn't find the exact error message for the Overtemp error.  Maybe I missed it.   Also, just curious where do these errors display on the 6300 without the front panel or when you are operating remote?

This is one of the two side fans from the 6500/6700.  The replacements I bought from Digikey didn't come with plugs on the end of the wires so I reused the ones from the old fans.  It was a simple unsolder/solder job.

Manuel & Michael,
Thanks for the info.  Do you know if there is an error code associated with these fans?  Maybe an overtemp condition error?

Do you know if this fan is equivalent to the one that came with the radio initially?  It looks identical and is rated at 40 CFM and has a "precision ball bearing" system.   Mainly want to be sure the airflow at 40 CFM is equal to or greater than the original fans.  

They are $12 and come with wires attached but not the plug.  So it's just a matter of reusing the old wires as Manuel noted or getting some plugs to attach to the new ones, or splicing in the connector.

 

Might as well have some of each type fan on hand if they also are common failure parts (but that is not clear, unless I missed it somewhere).   And if you are opening up the radio to replace the fans in the cage, might want to replace these as well.

The engineering sample arrived Friday.

It is a full drop in replacement. Same OEM manufacturer, same wire color coding and connector, same heat sink, and the same thermal adhesive pad. The only difference is the bearing technology, as the oem no longer offers the older style design. I am told the Hypro bearing is better, but I'm no fan design expert!

Most will opt to just unscrew and swap the fans, but for the purist, this is a complete replacement. No cutting corners. See pics below.

For those who preordered, I expect the fan order to arrive here Wednesday, and they should be in the mail and on the way to you by Friday. Watch for your shipment notification email.

For those who may wish to purchase fans in the future, I will have a limited stock on hand for $20 each, plus $10 flat rate shipping in the US. Inquire for shipment rates outside the US. If you think you want to purchase a fan, don't wait too long, as I don't foresee ordering another 100 fans anytime soon!

Thank you to everyone who preordered and made this possible!

UPDATE-

The fans arrived yesterday, and were shipped out to everyone last evening.  Everyone should have received their tracking notification emails by now, and those in the US should expect delivery by Saturday. Outside the US, allow a week or two.

Thanks again to everyone who participated and made this "group buy" possible.

For those who missed out, I have approximately 8 fans left at this point in time.  $20 each plus $10 shipping. Once they are gone, that's it!

As of this afternoon, the fans are sold out.

Should there be significant interest in the future, I'll consider another pre-order list.

Once again, thank you to all who participated.

I was getting a ticking noise coming from one of the fan bearings. I've added some additional information in the comments section of the video. Please feel free to post questions or comments there.

Got it. 
Thanks...

Edit:  This also verifies Eric's work to make a perfect match of the fans has been proven out. Well done...

There is a lot of good information in various places about the FAN replacement options.  Since it may be helpful to have it all in one place, I updated my web page with pictures, video, and links for the parts.  Thanks to Eric, Manuel and Dave for the info.  I'll keep adding to this as more becomes available.

Hi Larry,
There are actually either 3 or 4 fans in your radio depending on the model.    There will be 2 of the smaller 50MM fans needed for all models.  The 50MM fans are the ones Eric sourced.  There will be either 1 or 2 of the larger 80MM fans depending on the radio model. 

More info and pictures at my web page.

It can be confusing and that is why I decide to try can pull all of the pics, notes and video into one place.  Hope that helps.

The fan(s) on my 6500 finally gave up for good.  I had ordered 2 replacement fans from Eric K2CB (many thanks, Eric!).

Replacing the fans took about half an hour.  The video in this thread was very helpful.  Getting the cover back on the cage was the hardest part, but only took a few minutes.  Didn't have the hook tool which would have made the process easier.  Once I got the cover back on, everything else was easy and the 6500 is now working fine.

The only tip I have is to keep the old fan and parts well separated from the new ones.  They are almost identical.  The wires on the new ones are longer than the wires on the originals.

My 6500 was out of warranty and the price of fans was less that the cost of shipping the radio one way.

Al, I have used the exact same fans as found in the side panels of the F6k for over 10 years in Servers that run 24/7. I have never seen one fail electrically in use. The only failures seen are due being F-O-S inside badly maintained units.

So replacing those fans early is probably not required, but maybe good preventative maintenance if you happen to be in there anyways to sort out the other crappy fans.

Yes, was getting the FPGA error, occasionally at first, usually a restart got it working, then wouldn't start no matter what.

Only replaced the two under the cage, so no information on that.  If someone does replace the side fans, a video is VERY helpful.

Thanks John and G7BCX,
It sounds like the case fans don't fail as often, only FRS can confirm with numbers so this is just anecdotal.  But a few folks have reported bearing issues ( whining, clicking, etc).  The 80MM case fans are inexpensive and if I was replacing the 50MM fans and  the case fans have been in service for a number of years I might change them as well especially if it makes the cage work easier. 

My 6700 is 4 years old now and all the original fans are still working fine but I do have a full set ready to go if/when I need them. 

If anyone does replace all 4, please let us know what you find and as John suggests a video or even some pictures of the process would be helpful.

Regards, Al / NN4ZZ

I replaced the side fans on my 6700 a few months ago but didn’t take any pictures. You can actually remove the side fans by just removing the side outer black panels but you have to remove the inner panels to reinstall them. This is because the fans are held in place by some rubber isolators and you need to install the fans on the inner panels with them removed. The isolators are actually press fit into holes on the inner panels When someone does share some pictures you’ll understand what I’m talking about.

Folks,

We need another 30 or so fans sold to make the minimum order requirement again. For those who inquired, I have you on the list and accounted for. For those who want in, email me at k2cb@comcast.net

Ok, folks.

We are just about at the minimum requirement. At this point I’ll place the order and keep the remaining balance on hand for future need.

I will be placing the order with the factory sometime this week. Lead time is appropriately 7-10 days.

They will be $20 each, plus $10 shipping stateside.

For those outside the US, email me with your shipping addresss for an exact quote. A rough estimate, based on the last time around, is approximately $15 for first class mail, and $25-30 for priority mail.

PayPal to hamcables@gmail.com

I will reply to everyone ‘s emails later this evening when I get in from work.

Good Evening,

I replied to everyone direct via email this evening. Hopefully I haven't missed anyone.

While still somewhat short of the 100 piece minimum requirement at this point, in the interest of time, I have gone ahead and placed the order with the manufacturer.  I expect the fans to arrive sometime next week.  I will then turn them around within the follow day or two, depending on my work schedule.

If you have not inquired yet, but would like to be on the list, email me at k2cb@comcast.net


Thanks,

Eric

Update - the fans are scheduled to arrive tomorrow. They will go out in the mail to everyone by Monday.

I will have some additional units on hand for those still in need.

I haven’t had a chance to get back to my office yet, but I want to let everyone know that the fan packages shipped out via USPS this morning. If you paid via standard PayPal, you should have received an automated notification. For those that used F&F (and I thank you!), I will manually send tracking info shortly.

At this time I have about 20 fans remaining from this batch. At this point I can’t see there being enough demand anytime soon to meet another 100 piece minimum a third time around. If you think you may want a fan or two (or four!), you may want to act now before they are gone again.

Thank you again to everyone who made the second group buy possible. Especially those of you who bought extra units just to help meet the minimum. I made a note of those generous individuals who bought a few extra “just in case someone gets in a bind down the road” and offered to “make them available” if ever needed at some point.
