Question What should I use to control pump speeds on my liquid cooled GPU?

Apr 14, 2020
I am currently using an AIO for my CPU, plugged into the PWM header. The AIO adjust speeds of the fan based on my motherboards CPU temp readings (pretty basic imo). I just installed a nice water block on my GPU. However, if I use an extra PWM header on my motherboard, it adjusts the GPU fan based on the CPU temp readings. I can only set my motherboard to change fan speeds based on either CPU or GPU temps.

I would like my GPU to change its speed based on GPU temps, and CPU fans to adjust based on CPU temps. I cannot use MSI Afterburner to adjust GPU fan speeds, since I removed the original air cooling attached.

Am I missing something here? I feel like this should have an easy solution. Or do most people set their watercooled GPU fan speeds to fluctuate with the CPU, or the other way around? Is there a dedicated GPU header I'm just looking right past or..?

Also, for some context for me, what do people do when they have 1 continuous loop for the CPU and GPU? Or is this less of an issue since both parts use the same liquid for cooling?
