Random CPU fan failure

I've got an aging AMD 64+ running on a Abit AN8 board which up till now has been fine...until now. The CPU fan stops spinning, this causes the onboard alarm/temp sensors to go crazy and the system gently shuts itself down. What's strange is if I move the clear BIOS jumper and start it back up it works again so I dont actually think its fan itself, more worryingly the motherboard. Any other ideas? Suggestion. Going to have to look at upgrading if the problem persists cos I cant get replacements for any of these parts.
 
Fans go. They throw all kinds of strange tantrums in old age. Try replacing it if you can but there is naturally the chance that you are right and it might be the mobo.

I would not count the fact that it starts when you reset the bios as significant. It might as well be the fact that you shut it down and start it up again... A little extra juice at boot time does a lot for an ageing fan. It is like Viagra of sorts. ;)

agree, your fan sounds like its on it's way out, replacing the fan would confirm this.
 
Thanks guys, I'm just hesitant to go the replace fan route (at 200 odd bucks due to it's age). I'm going to get a multimeter from work to test if there's enough voltage going to the connector at the time that the fan stops.

R200? Dude you're being ripped!!!
 
You could also try a spurt of that non-conducting lubricating spray. I can't for the life of me remember what it's called... I think it was CRC spray. Quite expensive though.
 
He must be talking about some kind of Teflon based lubricant, some lubricants have Teflon in them and then they assume that is a good reason to ask outrages prices for them :(

EDIT: Also Teflon = Doom to a fan.

Use WynFlon which you can get at hardware stores and automotive outlets

That is exactly what I was talking about WynFlon has Teflon in it, if you use this it'll kill your fan far quicker than just leaving it as is. Teflon is not meant for bearings unless they were designed for it, same as chucking Teflon in your car engine, very bad!
 
It worked for me, it might not work for all applications.

I have used it on many fans and all are running years after application.

The same goes for car engines. I have used Slick 50 (Teflon) and never redone any of my engines, all cars were sold with between 250 000 to 300 000 Km on the clocks.
I used it on 1 Peugeot and 7 VW's. I might have been lucky or these cars where inherently good products.:)

I have redone many others though with much less K's on the clock.

LOL k keep doing that!

You can read that if you're interested though:

I've had 2 fans fail because I put WynFlon in it (Key ingredient being Teflon), the bearings seized, it's very easy to spin but it loses motion far quicker than it should, I've also used it with skateboard bearings with the same results (skateboard could be because of serious abuse tho).

After that I stopped using Teflon products altogether, this is my opinion of course.
 
I am not arguing, I am just stating that it worked for me.

I have read that snakeoil report long ago, but as I had good results I kept using Slick 50 until I bought a car with a catalyst and Lamda sensor, were it is not recommended.
 
If I can get my head on straight and actually remember, I'll go look for my can of the stuff so I can get the correct name. Don't think it contains Teflon, but I could be wrong. Never really checked. :p
