Connect The fan on the gpu card or straight to the psu?

post #1 of 5
Thread Starter 
Yes I know the questions is weird but I wonder. Would connecting the fan on the gpu will give extra weight for the card? I am guessing connecting it on the card just means the gpu will check its own temperature and control the fan speed. Its a Ati Sapphire HD4870 512 with an Accelero Twin Turbo.

Thanks for any kind of help

Yeah, if you want proper fan control I would connect it to the card. The motherboard/PSU connection will most of the time only provide a constant speed.

So it will not make the fan go slower or put any extra weight on the card? I prefer to let it blow constantly than the fan give a harder time to the GPU.

Well problem solved after seeing a test about results on using it on the gpu card and straight tot psu . Thanks For the help!

Fans use so little power, it really won't make any difference to the card. The card is designed to run with the fan anyway.

By weight, I assume you mean power consumption?

Well obviously on the PSU its going to run full blast all the time. But the cards are desiged to have the fan plugged into and and it can be controlled by software.
