How To Control Liquid Cooling Pump

[Techdude000]

Hello guys. Im building a custom loop for GPU + CPU. Should I plug pump into CPU header, or will this fail to cool graphics in case of an asynchronous workload. What can I do? Can I modulate pump speed by water temp? How?

What water cooling pump are you using?

Any 4pin fan header should work. But it may require a specific header depending upon proprietary software.

You misunderstand me. My worry is that if the GPU's are working harder than the CPU, then the pump wont crank up and the GPUs could overheat if I use the CPU Header. Can I control the pump by water temperature?

From the standpoint of the motherboard the pump is treated exactly as if it were a cooling fan. If you have temperature sensor headers on your motherboard, you can use the temperature to control the pump. I can do this with FanXpert 2 on my Asus ROG motherboard. But I realize that it probably isn't very common.

But you could use a fan controller control panel with the temperature probes installed on your graphics card. Or you could simply attach the thermocouple to your reservoir.

I've not seen an inline thermocouple for use in water cooling. You could possibly fabricate one using a "T" connector.
