Hi there

I have had this problem for a while and have tried everything to solve it to no avail - hopefully the community will be able to help me out.

The problem: I have a Corsair H80i GT water cooler which acts as a exhaust to the back of my system. It comes with 2, 3 pin fans which are connected to the splitter which comes out of the water pump. The cable from the water pump is the plugged into the dedicated water cooling fan header on my motherboard, which is an ASUS ROG Hero 8. The Corsair link cable is also hooked up to the motherboard. In my BIOS, the fans are set up as PWM, and I have installed the latest version of Corsair link and set up the default profile which has the pump operating at max which is fine.

It all works fine and my CPU temps stay at around 30 degrees or so and my system is not overclocked either. The fans on idle will spin at around 1000rpm which is fine and not noisy at all.

When I am gaming however, on something as simple as CS GO, the fans on the Corsair AIO will then start spinning at maximum at 2700rpm which is way too fast and creates a lot of noise. The CPU temps are still fine at around 30 degrees or so and the load on the CPU is only at around 10%.

I have no idea why the fans need to spin so fast when the CPU is not under much load at all the the temps are perfectly fine - it creates so much noise that is unwanted.

Did I plug something in incorrectly? Should I change something in the BIOS? Any help would be much appreciated.

Thanks - my specs are as follows for your reference:

CPU: i7 6700k
Mobo: ASUS ROG Hero 8
Ram: 16GB DDR4
Cooler: Corsair H80i GT
PSU: Corsair CX600M

As per the manual you're advised to connect the pump header off the motherboard's CPU fan header. If you were working off a PWM pump module like DDC or a D5 PWM variant then the pump header on your Hero would've come to use.

Switch your pump to the CPU fan header and the issue should be resolved.
