can i plug GPU fan directly to PSU via adapter?

[whiteknights]

hello guys.. recently i've found out that one of my Sapphire HD 7870 XT fans is not spinning.. it spins when i power on the pc for 1-2 seconds then it stops, also every time after i quit a game it spins for around 1 minute then stops again.

i've tried almost everything possible. and now im thinking of plugging the gpu fan connector directly to the psu, to see if that could make the fan spin normally again. so is it okay if i did that?

my PSU is Thermaltake 450w.

To begin with, are you sure that you have 2x6pins plugged from the PSU in your GPU? Also if you plug your GPU fan in the PSU, instead of in the motherboard, it will always run at 100% and you won't be able to control it.

thanks for your respond.. my PSU have only 1x6pin, so I'm using one molex and the normal 6pin from the PSU, and im using that since 3 years without having any issues.

Get a new PSU, a HD 7870 - 23A and a 500W psu minimum

It also could be new drivers that don't spin the fans till the card gets hot enough to warrant cooling.

For a lot of GPU's, the fan only spins up when under load and it needs more airflow..

thank you, actually i tried different drivers, from 14.4 till 16.1 and nothing happened.. also its just one fan that isn't spinning, the other fan is spinning normally.

i doubt that 7870 XT fan wasn't spinning from the beginning, because i noticed a temp increase by 7 degrees right before i discovered that one of the fans isn't spinning.

plus even under load the fan doesn't spin, it just spins right after i quit the game for 1 minute.
