Hi

I want to replace the fan of the FPGA and the CPU. I see that the ones that have my 6300 are from the brand ADDA and model ap0512hx-j96. I look for them but can’t find them, says out of stock. Did someone knows where can I find them? Or know about some others that can be used? Thanks

A large order of the 6300/6500 fans was placed here by one of the contributors here on the reflector.  I am not what he ordered and sent to all of us with the 6300/6500 but check the archives or someone will answer you as to the part number, etc.

I would create a helpdesk ticket and talk with Flex before buying anything, there aer some real gotcha's in doing this the wrong way.

WP3C,  this has been a long topic here, please research the community before going too far. If you do find some replacement fans you need to determine if replacing them yourself is an option. Read about it..

Flex does have replacement heat sink and fan units that you would need to have them do it for you because the old heat sinks have to be removed and the new ones installed. If you do any of this yourself,,it is at your own risk.

I may be wrong but from what my feeble mind remembers, you can replace the fan without removing the heat sink, which of course makes it much, much easier..

Jim I said, that if he can not find just the replacement fans then the heat sink will need to be removed and changed. Not something a person should attempt on their own.

Your 100 percent correct Bill.  AL's post below this one pretty well covers the fan info.

I am on my 3rd fan replacement in my 6700. Have pealed back the label but there is no hole to oil. Have found these fans seem to run fine on the bench [after removal] for a few hours but then start to vibrate and slow down. That's when the error displays on the front panel. You can remove the fan by taking out the four screws that hold it to the heat sink and vacuum it out. Try to pull the fan blades away from the base and either use compressed air or a vacuum to clear any dust inside that fan. Then run it on a 12V supply for a while to see if it holds up.   
Does anyone know how to get the blades off the fan base to expose the bearings?
Hope this helps;

I sold this 6300 to Alfredo and I never experienced the fan failure prior to selling it to him. I would never sell anything that was known to be defective. Very unfortunately for him, this problem occurred less than a month after the transaction.

But in hindsight, he was going to ship it to a remote location and it is better that it failed now than after it is installed at the remote site.

I've offered to buy the original fan and replace it for/with him, or buy the radio back so he can find another, at his option.

If he chooses to return it I will deal with the upgraded FGPA fan when it becomes available. He may not have the luxury of time to wait for the upgraded kit. He'll have to find another radio for his mission.

You may need to take the fan apart to oil it. All of these fans can be serviced. There will be a cap over one side to open. I have done a few computer fans and they go back to running just fine.

I have a filter inside my radio in between the the walls in the case, the filter stops any dust from entering the radio. Over 5 years now and all the fans do not even have a spec on them and running very well.

On the bottom side of the fan is a black sticker that can be peeled off with your finger nail or Xacto knife. The fan shaft is exposed and can be lubricated with a small drop of light oil. Not sure if this will bring the fan back to life but worth a try.
Hope this helps.

I've submitted a Support ticket to see what the factory fix is, what it will cost and the time it will take.

I would talk with Flex first. I was on the phone with them about my 6400 last week and the subject of the 6300 fan problems (I have 2 of them) and if I remember correctly he said they had a upgraded fan. If I was going to replace the fan with the same one I would do it myself now (already sent one in to have it done). If I was going to put in the upgraded one I would have flex do it. The fans I have (purchased with the big buy one of the members set up for everyone about a year ago). Those are just remove the screws from the fan and the heat sink and then re screw new on back on. If I was going to get the newer fan I would send in to Flex. 
I am going to keep my 6300 here at home as a backup rig and just have the other 6300 at my cabin, it does not get much use anymore. Good luck!

Thanks Bill, that shows well, most of the time a little oil will free the bearings up and run well.

I had text/email communication with Alfredo yesterday and he successfully serviced the fan(s). The radio is running and he's going to leave it powered on as long as he can as a burn-in test period before he has to ship it off.

Thanks for all the assistance folks. The Flex community rocks. I hope to own another someday.
