How to control a case fan using the PWM from a graphics card?

[Limester]

I recently purchased a Corsair H90 and an NZXT Kraken G10 to liquid cool my Nvidia GTX 770...
I am currently using the fan controller on my case to change the speed manually, however this is rather annoying since I have to change the speed by myself when I want to play a game!

So I was wondering... Is there any way of using the graphics card's PWM signal or GPU temperature to dynamically control the fan's speed?

Many thanks in advance,

Liam

To controll all the PWM fans on your mobo and GPU, get something called SpeedFan (just google it). It enables to control most of the fans on your computer.

To dynamically control gpu fan (custom profiles), then only MSI Afterbuner does it best. Afterburner is known to be the best overclocking / control software for any gpu's.

Thanks! It seems SpeedFan is more useful than I first thought! My radiator's fan speed is now proportional to the temperature of the GPU - after a little bit of tweaking of course... It works brilliantly! I did have to mess about a bit in the task scheduler to get it to launch at startup, but I guess you can't have everything done for you eh?
