Hey guys.

I have two EK Phoenix kits. One is a 360mm for the CPU and the other is a 280mm for my GPU. Right now I have a Silverstone PWM hub off the one PWM port on the mobo going to both MLC kits. This works but is less than ideal since the pump and fans for the GPU rad are still controlled based off of the CPU temps.

I see most of the new boards have multiple PWM headers, at least 2. I know plugging the CPU kit into a PWM header is straight forward and I just set the smartfan parameters I want based on CPU temp. However, plugging in the GPU kit into another 4 pin PWM has me curious. Is it possible to have the board control the GPU's kit pump/fan speed based on the GPU's temp? How would the motherboard know what temp the GPU is at?
 
I hope I haven't made this too confusing.

Yes, not only is it possible, but people -- including me -- are doing that.

Very cool! I'll check out that guide when I get my new mobo. Too bad this isn't natively supported in BIOS. That would be much easier.

The way I set it up, the BIOS sets both fan headers based on CPU temperature. Then, in Windows, SpeedFan takes over and the BIOS fan control is overridden.
Please be aware, though, that BattlEye anti-cheat software makes SpeedFan stop working, so any fan controlled by SpeedFan will freeze at their last setting as soon as you open a game with BattlEye.
