CPU Fan has failed

post #1 of 12
Thread Starter 
Hi,

I have a HP a6110n computer
AMD Athlon x2 4400+ processor
2GB RAM
Windows Vista Home Premium
Asus M2N68-LA (Narra2) Motherboard

My computer was overheating a lot with the stock fan. I replaced it with a Cooler Master Hyper TX3 heatsink and fan (92mm).

When I turn on the computer I get the message saying CPU Fan has failed, computer will shutdown (then it shuts down). However, the fan is spinning properly. Furthermore, if I unplug the power cable from the back of the entire computer, wait 5 seconds, then plug it back into the computer, then turn it on - then I don't get the error and everything is fine and I go in to windows and work, temps are fine, etc.

So basically before I turn on my computer each day, I have to remove the power cable for a few seconds and plug it back in to avoid the "CPU fan has failed" error.

The fan has a 4-pin connector but the motherboard only has a 3 pin slot, but it is keyed to fit on a 3-pin slot.

My guess is the new fan operates at a lower speed, but my computer thinks it has failed. This HP computer has very limited BIOS options so I cannot disable the fan detection (prefer not to do this anyway), nor can I reduce the threshold on the RPM sensor.

1. Any ideas what to do?
2. Is there a way to somehow access the more advanced settings in BIOS by installing an update or something?
3. Why does removing and re-inserting the power cord make the error go away?

Thanks

Nope. The OEM motherboards are usually stripped down ; thus also they have very stripped down BIOS's. Is there any other fan plugs or any other way to ignore that warning?

I can plug the Hyper TX3 fan into the chassis fan slot, and plug the old fan into the CPU fan slot to trick the computer and avoid the error. But if I do that and the Hyper TX3 fails, the computer will not detect it and then I risk frying the processor.

When you replaced cpu cooler, your cmos battery took over.
Sometimes it hiccups in transition, from PSU to cmos battery.

Your bios in short, has problem.
Go to bios & reset to defaults and save it.
Your bios hopefully will now be happy.

Do it in bios , not by clr cmos jumper.

it happened to me, but my pc didnt turn off. i had the cpu fan connected to a wrong slot, because i didnt know the 3 pin would work on a 4 pin (lol)

crap. well i guess i will just have to put the stock fan back in and wait until a cold winter day with the heat off and windows open to do any video conversion work to avoid having this POS computer turning off due to overheating.

Dude, hit F11 on startup instead of F1 to get into the advanced BIOS.

There you can edit fan options like fan curves, and turn off the warning.

I have a P5LP-LE in an m7390d, the F11 one offers plenty of options whereas compared to the F1 one, where you can only 'look' at stuff.

Thanks Volvo. I tried hitting F11 and various other buttons, but only one took me to BIOS - and that was the stripped down BIOS I mentioned earlier.

I would appreciate any other ideas, including suggestions for a comparable aftermaket fan that would work with my motherboard.

Thanks

happens to me sometimes

i just press f1 and it boots normally and the fan spins..

Even in the fan dies your computer will not just "Fry" the processor. They have a thermal limit and when they hit it the computer will shut down regardless of whether the motherboard tells it to or not. You are perfectly safe to plug the Hyper TX3 fan into the chassis fan slot.
