I bought a Cooler Master Hyper T4 today and when i mounted it, my PC said "CPU fan is not working system will shut down in a few seconds to prevent damage" and I know my fan is spinning and i used the stock cooler to boot my system up then hotswap the fan and everything is working fine. But I can't normally boot my PC and I already checked my BIOS settings for the smart minimum cpu fan speed and I don't have that option. I think it's because of the minimum fan speed and I don't know how to change it or what to do, is there any way how to bypass or remove the fan speed testing without BIOS because that's not an option for me? (The Cooler is connected to the correct 4 pin header on the motherboard, where the stock one was plugged in, and there is no other header of the same type for my new fan on the motherboard)

Motherboard: Asus IPBL-LA (Berkeley)
CPU: Q6600 2.4 ghz
CPU socket: LGA 775
Cooler: Cooler Master Hyper T4

Update: I left the PC to run over night and then i restarted my PC and it booted up without any issues, but when i turned it on again after a few hours its the same problem again, is there a way to force the speed of CPU without BIOS because my BIOS is literally useless?

Update 2.0: I have found a way to temporary fix the problem. I don't turn my PC completely off, I put it to sleep and will have to do so until i get a new motherboard.

As a work around, get a proper 4-pin fan splitter. Connect it to your MB CPU fan header. Plug your old CPU fan into the side of the splitter with four pins, so its speed is reported back to the motherboard. Plug the new CPU cooler fan into the side of the splitter with a pin missing, so its speed is NOT reported back to the motherboard.

Aim the old fan at something that you would like to keep cool. :)

But am I able to plug a 4 pin fan into a 3 pin socket and the 3 pin socket into the 4 pin socket? And will my PC boot if the 3 pin case fan is in the 4 pin CPU socket? I still have my stock cpu cooler, that's how i booted my PC and then plugged my new fan while the PC was still on.

BTW, the low speed fan warning RPM is under HWMonitor on the POWE:R tab of my ASUS bios. It has options:

IGNORE
200 RPM
300 RPM
400 RPM
500 RPM
600 RPM

=============

Your problem doesn't make a lot of sense. Any decent PWM fan should be turning fast enough at startup and report an tach signal back to the motherboard. I wonder if there is something specifically about the CoolerMaster fan that the MB doesn't like? Perhaps, it's just going from a high speed small fan to a low speed larger fan with a really high RPM trigger in the BIOS? I don't know...

I think, if I were in your shoes, I'd order a really good 120 mm PWM fan and put it on your new cooler:

It is a very big fan and doesn't needs to spin 600+ RPM on startup when the huge cooler isn't even warmed up, but maybe it could be lack of lubrication? I read somewhere that a guy with a similiar HP PC had a similiar problem with the Cooler Master V8 and after lubing it up everything was fine, but I don't believe that's my problem and yeah my motherboard really has no options it is an awful board.
