PWM via CPU or GPU

So I've been looking into liquid cooling my PC and I think I've got the gist of it except for one thing. What do I base my fan/pump control off of? CPU or GPU?

 

I'm doing a CPU and GPU loop and EK (liquid cooling guys) recommend a GPU to PWM fan adapter to have your GPU control some or all of the fans in the case if I'm doing more GPU intensive tasks. Now I don't necessarily do GPU intensive tasks except for gaming but I don't know if that is enough to base my entire pump or fan control off of the GPU for. I was thinking about having my GPU control the PWM pump speed while my motherboard headers control the fan speed.

Is that smart or should I just leave it all alone and connect all the fans and pump control to the motherboard like a normal human.

 

Thanks for any help!

Thanks but it doesn't exactly answer my question. I'm just wondering if I should base my pump and/or fan speed off my GPU PWM header rather than the motherboard CPU one because I do a lot of gaming and my GPU is hotter than my CPU more often than not.

Just use a PWM header on your MB to control the fans. No you won't be able to control the fans directly from the gpu temp but when the gpu is cooler the cpu typically will be too. Have you tried SpeedFan?

1) Sit at desk.   2) Repeatedly slam forehead against desk.

 

I never said I was smart, just smart enough to be dangerous.

 

 

ORLY?
