Hello all,

 

Well i just build a new pc and i cannot get the fan to run on my corsair tx 650 v2. it initially starts up for a few second then stops and doesnt come back on. I know its temp based to get the fans running on this model but i ran prime95 for about 30 minues so far and the fans still havent turned on also i have ran 3dmark11 and the fans didnt turn on.

 

thank you

    Some power supplies have a fan that won't turn on until the load on the power supply gets high enough, or until it heats up enough.  Prime95 only stresses the processor.  Try Prime95 (with three threads, to leave one core free) and FurMark at the same time and see if that gets the fan to kick in.

    I did as you said with the Prime95 and FurMark fan still didnt cut on. Also  i am running 9 fans on the case.

    Uhhhhh...

    Those 9 fans are pulling outside air into  the PSU. You know, cool air.
