Why do I get this message "CPU Fan has failed" at boot

[yomafire]

Well I know how to disable this..but I want to get this fixed so I can control and monitor my cpu fan. I would like to slow it down. How would I do this since the error is occuring and the motherboard does detect it.

Hi!

I had the same problem with A8NSLI deluxe, Athlon 64 3200+ and the stock cooler.
After some thinking I figured that the message appeared becouse the fan was running too slow. The funny part was that the fan was running slow (or not at all) becouse the motherboard had slowed it down due to the low CPU temperature. My solution was to turn the
cpu fan monitoring off.

Btw: I had the same issue with my chassis fan plugged to the motherboard

If this happens with the original "boxed" fan, it's time to approach the board maker for a BIOS update that sets or lets the user set the RPM warning threshold lower.

Yeah, I had an old abit motherboard that wouldn't boot because the low speed fan on it wasn't fast enough to be detected by the bios. I had to hook up a different fan just to get into bios to shut that feature off.

well im using now Qfan. basically its really quiet now but my temps are at 46 load

hmmm

Anyway to manually control the speed of the cpu fan?

At 46 Celsius, nothing is going wrong at all. You're at least 20 away from critical temperatures.

ya but before at default cpu fan speed i was around 36. I know 46 aint bad but isnt there a program or something to control cpu fan speed?

Tried that....basically all fans show at 0 rpm. I guess this is linked to the "CPU fan fail" message when boot occurs

Im mad!

Q-fan sometimes defaults the rpms of the fans / cpu to 0 at bootup if it senses the temp readings to be sufficiently low. there is no real way to bypass this other than to disable q-fan altogether and utilize a utility like speedfan.

Guys,

I have no luck with this board. I cant manually adjust my cpu fan speed. I disabled Qfan and the fan just fast and loud. When I use speed fan it does not detect any fans and therefore I cand adjust

what the hell.

My rig is always idle 32 oC and max throttle 42 oC with 90C.

I don't like the new Qfan, in old system, I can control them to what speed.

In this new, I use Qfan control, slower your fan speed control (option from 800-1200-1600, you choose what you like), besides, I create a board to control add-in speed, then my fan runs slowly and no more noise.

Sorry, I use A8N32-SLI Deluxe now. I remember what I done before.

Good luck

Speedfan....learn it, live it, love it....
