I need help correcting a possibly mistaken belief about AIO pump connections. For the past 5-10 years, I've been connecting my AIO pump (the part that sits on the CPU) to a constant 12V power adapter, believing the pump should always run at 100% speed.

However, I'm now questioning this setup. Modern motherboards have dedicated headers like CPU_FAN, OPT, and PUMP - should I be using these instead? Where did I get the idea about needing constant 12V power, and have I been doing this wrong all along?

If motherboard has AIO_PUMP header. Doesnt it just run at 100% anyways? I thought the only variable speed is the 2 or 3 fans on the radiator?



Can someone help clarify the correct way to connect an AIO pump? Thanks!

You can run it either way, variable or fixed. I dont think there is a wrong way.

I have mine plugged into my header, and lately I have been running it variably to enjoy actual pc quietness..
 
I have a D5 that has SATA for power and an RPM wire to monitor RPMs. Mine is variable with dial, so I have it set to 50%
