    Hi, during boot-up of the pc says CPU fan isn't working, its pretty clear that its working, I've tried a new fan and a new power supply. Ran system temp checks and the CPU temp is right around 40, which its always ran around that
    Temp. I have no control of the fan speed, its a 3 wire fan. Does anyone have any ideal what the problem might be?

    see if can get into the bios & check for hardware monitor or someting like that to see if it shows the cpu fan speed in rpm.

    I can get booted into windows by pressing f2, also can get booted into bios, as I was just reading from Google, maybe could be a issue with the BIOS itself? This problem didn't start til I purchased a new motherboard

    have you plugged the fan into the right outlet on the mobo.. double check it's on the cpu fan point and not the case fan point ;)

    Yes its plugged into the correct location ;)

    Edited-I powered the system on and it boots fine without the message of fan not working.. system did a update/restarts/message shows up again/I power off then back on, boots without message.... This is some crazy stuff?

    so I shutdown the system, remove cpu fan, blow out fan/case/ remove cpu paste from both cpu/fan, clean and new paste, install fan, reboot and i get the same stupid message...

    This is bugging me to death... Thinking I might update the bios to see if it helps..

    Ok just wanna let everyone know that I kinda solved this? Im guessing the system was looking for a system fan to be hooked up also (didnt have this before replacing motherboard but the new 1 must look for it?) anyways so I take a system from 1 of my other systems and hook it in the chassis fan spot and all is good... boots fine everytime... I dont know what could poss be different from the 2 motherboards, they are the sametype of board,maybe the system the board came from had a chassis fan? (the board I had purchased was a used motherboard).

    anyways Thanks for all the help!
