    System Fan has failed?

    Asus mobo with G33 chipset, Intel Core 2 Q6600

    Recently got new case which has 2 front fans when my original case only had 1. However the system fan I'm going to assume is referring to the fan/cooler thats attached to the motherboard?

    I've checked when powered up that the gfx card fans work, the fan attached to mobo works and I have my two fans at front of casing is also powered on.

    So this system fan fail, is this an early sign that my CPU fan is on its way out?

    Any help would be much appreciated from the great hexus forumites.

    P.s. I can't get access to BIOS either as the BOOT screen loads and practically immediatley displays the error and I'm prompted to Press F2 to resume.

    Re: System Fan has failed?

    I'm guessing you now have too many fans plugged into one or more motherboard headers...?
    Some lower-end boards will not support multiple fans on one header...

    A quick look at the Asus P5K-VM motherboard (which is the first one I found having G33 chipset) shows one 4-pin CPU fan header above the RAM slots, a one 3-pin chassis fan header to the right of this and one 3-pin power fan header to the lower left of the CPU...

    The manual says: "The fan headers on this board each support cooling fans of 350 mA~2000 mA (24 W max.), or a total of 1 A~7 A (84 W max.) at +12V".

    So check what the ratings are of each fan and add up those where you have more than one fan - On the CPU cooler, for example.

    Check what the warning level is set at, it'll dypically default to something that would indicate failure on a stock fan. If you're sure its running and have a 120mm cooler or similar the fan is likely running slower than the board thinks safe.
