Both are down due to fan failures. Both are kept in pristine environments separated by approximately 200 miles (i.e. this isn't environmental).
Anyone else have fan failures on the new models? Since flex is making me pay the return shipping for these is there a home-fix for this?
I have owned a 6300 (fan died within warranty)
I owned a 6700 (fan died within warranty)
I owned another 6700, power output issue - died within warranty
I owned a 6400, came DOA
I own another 6400, fan failure within warranty (backup radio - probably has been used a dozen times)
I own another 6400, fan failure within warranty (backup remote radio - probably has been used a dozen times)
I own a 6600, is ok so far.
I own a PGXL - had to be returned to be fixed in the warranty period.

I bought fan from NewEgg. https://www.newegg.com/aerocool-shark-140mm-black-edition-case-fan/p/N82E16835129057?Item=N82E16835129057
New fan has been running nearly 24/7 for the past year without issue. So maybe there was a bad batch of fans?

They suggested I ship them back but didn't say replacing the fan yourself was an option.

Radios are always run through the amplifiers (i.e. < 50 watts) except if running a QSO party. The 6400 has probably only transmitted a few times as it's just a hot-backup for the 6600.
Here's what my log looks like... these don't exactly see a lot of use. Yes my last contact is from June 2019 and October 2018 before that

We have no trouble sending replacement fans to customers confident in their ability to replace them. It saves everyone time and cost. For the 6400/6600 series, installing a replacement fan is a straight-forward task that can be completed with simple hand tools. All 6400/6600 radios are under warranty so currently, no customer that owns that genre of radio will have to pay for a fan. Provided we supply the fan, replacing one in the field will not void the warranty. Note that simply stating there is a fan problem is not enough, a service ticket needs to be opened and one of our support techs will need to verify the diagnosis.
One of the things we have to do regularly is deal with components that move to end-of-life. This happens on a regular basis with lots of components in our radios including passives, actives and mechanical parts. It is simply a reality in the electronics business. The existing fan for the 6400/6600 went end of life (EOL) a few months ago. When that happens, engineering performs a search for a replacement and tests several candidates. They qualify the candidate against specific requirements that for fans, go beyond voltage, current, speed, and cfm specifications. So please don't think you can replace any of our fans with something you find elsewhere. That will void the warranty and could end up being a costly error. BTW: Engineering has selected a new fan and is finalizing the mounting requirements for it now.
I hope that answered some questions and concerns you may have.
Best,
Dan
P.S.
Replacing fans in the 6300,6500 and 6700 radios is another thing entirely, and though we will ship fans to customers with out-of-warranty radios that ask for them. I recommend sending the radio back to us for that repair. Replacing them is still straight-forward, but more skill is involved and you will need more specialized tools.

Really a great looking setup your built. Congratulations! I like what I don't see - that is the lack of clutter my radio room seems to end up with.
On your help ticket correspondence the guess is you are posting what you already posted to FRS through the help ticket process? The help ticket process changes the interaction from passive to active (and tracked with metrics for managerial review), and anything you put into that system gets to the right person right away. In addition to just doing a reply with your added comments above the line as they say, you can also log into the help website and add information there. Expect you know all that but not everyone reading the community will.
Fans are bothersome troubles - I've replaced failed fans on a 6300, but haven't had any more failures on the other radios (a 6600M on 24/7 and several 6700s).
Had other failures as well - one TenTec add on fan died (it was also a computer type fan) and in the last batch of Dell machines bought (eight in that group) one lost a fan within the first two weeks and one after a few months.
I'm wondering if the supply chain for small electronics fans is being affected by varying levels of Quality Control, introduction of non-spec fans (possibly incorrectly labeled or outright counterfeit), age/transport/storage induced problems, over-specifying OEM games (where the claims are made but the field performance is less) or other issues?
Again a great looking shack!

I try to keep the clutter in one of my outbuildings where I have spools of cables, boxes of spare parts, diagnostic tools, etc lining the shelves. I just keep a small inventory of that stuff in the cabinets in the shack. I'm no fan of clutter but since the shack is so small I had no choice but to keep it clutter free which has worked out well.
I submitted the tickets and passed along videos for each showing the fan errors but I got RMA numbers and shipping addresses to send the radios. I haven't re-addressed the tickets yet since Dan responded here and I replied to him. Hopefully he can jump in the tickets to remove the RMA and change them over to "shipping customer fans". If he doesn't get around to it today I'll reply to each ticket individually asking if that's a possibility.

I had two thoughts based on my PGXL temperature and on my current activities on lightning. You may want to consider putting your amplifiers well above your Flex radios. Mine amplifier generates a lot of heat and goes straight up. It would cook my 6600. Doesn’t look like a lot of room for airflow. The bottom plate of the PGXL is a thick piece of aluminum that does get quite warm so I give it space on bottom as well as top. May also want to consider an additional rack fan connected to a thermostat. Heat is the enemy of semiconductors and electronic components and directly affects the mean time between failure.
That said your fan failure is a component issue or possibly a component in the sensing circuitry.
The second question relates to your lightning arrestors on the wall. I am just setting up my lightning protection plans. PolyPhaser has some great articles that are on their website. I have a vision of 50,000 amps being applied to that area. You may also have arrestors at your towers but was curious if they get connected to a single point ground with copper ribbon/strap?
As a side note a 2kw PolyPhaser unit has a 600 volt +/- 20% trigger point. With higher VSWR, the voltage gets much higher. I put in the 3kw PolyPhaser units that trigger at 1200 volts. You may say your VSWR is 1.15:1 but put a load of ice or other abnormalities you may get a higher limit. Last week a friend just got a direct strike. It can be painful when it happens.
I moved my radio and amplifier to a different room and love it. Even with the door open my shack is quiet. Too much heat to put it in a closet.

Thank you. They aren't used enough that heat is an issue. If it is I do keep a fan in my shack that I point at the rack if I want to run a contest. Fortunately my kids keep me busy enough that my time isn't preoccupied with contest at the moment.

I have heard from others that the fan N3HEE linked to above is the fan that flex had them install in their radios.
Barring flex asking me to keep quiet about what fans they want me to install I'll share the information when available so others can self-fix when they have problems.

My 6600M fan is failing on me also. However I'm moving to a new QTH so the radio is packed up right now but when I get settled in at the new QTH I will replace with the new fan then.
My fan started to make a strange noise as if the burring’s having gone bad.- 144 Posts

I'm sure you have started a Help Desk report anyways as you should. If it is the fan going they can send you a new one that you can install yourself.

Yes I did and confirmed that the fan is bad. I tried to replace with a Noctual fan and it worked better than the stock fan at low speed but unfortunately due to the way FRS has programmed the fan control software if the radio see the RPM’s go over 1500 it will shut the radio down.
You can read more about that here: https://community.flexradio.com/flexradio/topics/6600m-fan-speed-questions
So when I get done with my move to my new QTH I will have FRS send me the new “Approved” fan I will install it then.- 144 Posts

FYI They have decided not to send the fans to me.
They think the failures are my environment and don't feel i'm competent enough to fix them myself without damaging the radios more than they already are.

So let me get this straight you own (2) 6400 (1)6600 and (1) PGXL. That’s more than $15,000 worth of FlexRadio product not to mention the other flex radios you have owned in the past and they won’t send you a few fans???
That’s just crazy! Replacing the fan in the 6400/6600 is as easy as 1, 2, 3
1. Remove top and bottom covers.
2. Unplug the fan connector from mainboard.
3. Separate fan from rubber mounts.
Then just reverse procedure to install new fan.
This is not any more difficult than changing a fan in a PC.
If they won’t let you do it they should at least cover the shipping cost.
Maybe try contacting them again and
see if they will re consider?

Are you sure you don’t work for flex? You opine on every post with an official-like-response and have never publicly said anything bad about them. Then when a customer has a problem you assume it’s the customer’s fault and laugh at them.
Sure seems like you are a customer support employee.

I also would much prefer to change the fans myself instead of having the radios bounce around again in long-haul tractor trailers and delivery vans, not to mention tossed around by package handlers and drivers, falling off moving belts, etc. etc.
I’d keep pressing for them to send the fans. If FRS wants to see the original fans, they could
be shipped back separately.
A few months back someone posted a picture of a PG XL that had a bracket holding a subassembly literally torn off the chassis in shipment. There are probably other cases where damage is not that apparent, and might take time to manifest itself.

It isn’t possible to distill exactly why they want to do the repair themself other than they believe the best fix involves bench work at their end.
I’ve always been appreciative of any of my radios sent in getting their full test treatment as part of the service routine.
I’m thinking I wouldn’t have lost a couple weeks prevaricating and attempting to renegotiate downwards the high level of service actually included in my radio purchases. Might have picked up the phone to see if they might have a loaner to keep me on the air while my radios were off being serviced.

I’m afraid we’ll disagree about being appreciative of our radios getting a checkup. I’d much prefer my radios to come without defect and therefore not need to be sent for a repair and checkup. When defects are found I expect the manufacturer to treat me graciously and to correct their short-comings without further expenses. It’s enough that I have to dismantle that portion of my station, box the radio up, ship it off, unbox it, and then put the radio back in to service.
We’ll also have to disagree about prevarication and whether the service level I seek is downward or upward. I think that would be clear enough without having stated it, though. I also think its clear that your post is nothing more than another veiled jab at me and defense of FRS. Gaslighting would be the term.
Fortunately I have no immediate need for either radio so there is no rush in reaching a resolution. Sometimes the right path isn’t the quickest.

And here we all thought Flex withdrawal syndrome was band with one radio down...How does one cope with having two down at the same time? I doubt it gets much worse than that.

We’re all guessing here.
Sorry offense was perceived where none was intended. I actually wanted to avoid taking a poke by relaying what I would be doing, and actually have as some of my radios have needed repairs/updates.
Hope you get your radios fixed soon. Would be interesting to learn what the issues are found to be.

I've been busy with stuff not radio related. I bought the shark fans from amazon nearly a month ago and replaced them in the 6400 at my QTH today. The radio booted right up and is functioning fine. The other radio I'll hopefully get around to fixing in the next few weeks.
Shameful IMO that I had to pay to fix it in the warranty period.

You can try to simplify it any way you want, but the fact of the matter is that these failures have occurred in three different shacks with three different antenna systems. I don't think it's unreasonable for anyone in my shoes to be pretty damn sick and tired of it now. If (as they say) they want investigate why they failed they can pay for the shipping to experiment with my radios. Since they did not, it naturally leads one to believe that the failures aren't that uncommon and that they don't really care. The e-mails I've received support the idea that the fan failures are exponentially higher than publicly reported and specifically people have told me that they don't report them because the cult of flex users (of which you are a board member) attacks them.
Go be unhelpful somewhere else.

Thank you. How do you know which fan has gone bad? Is there anything special about that fan or will any high end 140mm case fan work?
I'd rather replace myself than have to ship it off. What do they do about warranty status if you're breaking in there installing your own fan?
Joe N3HEE
Check with Flex for approval before you proceed so you don't void your warranty.
Not sure why Flex is charging for return shipping if you are under warranty ?
