    Well i dont know if this is the right place to post this but .. like the title says, my cpu fan just stopped working.


    I was running my computer overnight(not the first time) and the next day, i started to unrar a file(probably irrelevant) then my computer rebooted.. I was like.. wtf?? so i restarted thinking it was nothing. then it wouldnt restart.. i tried again 4 hours later(when i came back home from work) then it worked and froze, thats when i finally opened up my case and found out my cpu fan wasn't spinning..

    I tried the fan on another computer and it works so i'm guessing it's the motherboard at fault?

    A few days before I went into bios the hsf was at ~4800rpm and cpu temp at ~40C

    My computer specs:
    O/S: XP Pro
    CPU: AMD 1.33 Athlon
    HSF: Tt (duno which one, it works tho)
    Mobo: FIC AZ11EA (almost 2 yrs old)
    GPU: Radeon 8500
    PSU: 300 watts

    Well... I just wanted to know if anyone had any idea what happened, if a mobo just goes bad of old age?

    I had already ordered a MSI k7n2-L coz i was planing on upgrading my computer in a few months anyway, but this even t just sped things up.

    If the draw is too great for the motherboard to handle the load, then it will eventually kill the fan header on the board. That is one reason that I always recommend getting a 3-pin to 4-pin convertor. This allows you to connect the fan to the main power supply and never have this problem. There are even several different varieties available that have a yellow wire connected to a separate 3-pin connector that still allows the system board to monitor fan speeds.

    Its most likely your Power supply...

    Motherboards don't control the electric current running from your power supply to your fans...unless it takes it electricity from the mother board 3 pin connector. In that case it can be your mobo but it might be its own fault...maybe something isshorting it or something. Try just using the just the essential stuff...and try that. I think its the power supply that is getting old and not giving the mpother board suffient power to push everything on that board. Try a new Power supply..have you tried that?

    Wait a second. Did you say Wiggo that you recommend not connecting the cpu fan to the mobo but to the power supply itself?

    Yes, I understood what I read, which was all of it. And it's not always easy to understand what you guys right, with all the abbreviations and lack of correct grammar (periods and what not).
