Hello there. I own a custom loop water cooled PC with specifications that match my preferences. Recently, a friend who is assembling my system added water cooling to the motherboard and replaced my pump with an EK-D5 PWM G2 Motor (12V DC PWM Pump).
On my rig, there are four fans. The ones you should pay attention to are the two fans that cool one double radiator—they connect to the CPU and CPU opt header, though they are not PWM. The water pump is linked to the header above, which matches the manual description.
My issue is that I can't adjust the pump speed using AI suites fan expert. After pressing tune, it lists the fans' characteristics but doesn’t change the pump speed when adjusting. What should I try?

1. the headers can control both PWM and non PWM devices. make sure you select PWM mode for the pump.
2. there is no practical difference in cooling with pump speed over 30%. (that's why IMHO D5 Vario is the best, set on 2 and forget)

my friend suggested linking your pump to cpu header since it fails to recognize the pulse signal, which affects its communication with the other components like the pump and cpu_opt.

it's unclear whether you're trying to link the pump to a PWM-compatible header, since that would prevent controlling the pump.

I just transferred his words
😛
He seemed to mean that if the motherboard doesn’t recognize a PWM signal from the CPU fan (since a non-PWM fan is connected at the CPU fan port), it assumes there’s no signal, which prevents me from controlling my water pump.

Certainly. Here is the rewritten text with the requested adjustments:

Each header can be configured to manage either PWM or non-PWM functionality.

Sure, I'll review it more when I get back home. Just got about 20M on my PC. Thanks!

I'd recommend not using PWM on a pump, especially a D5. There is not a benefit to constant variation of pump RPM based on instantaneous temperature readings.
Water temps change much, much, much more gradually.

It seems you're right about the setup, but I couldn't adjust anything to increase the pump speed—it was already at 100%. I resolved the issue by connecting my pump to the CPU fan header and the two radiator fans (one for CPU opt, one for the pump location). Now I can control the pump speed. I'm setting it to 60% and it creates a slight "wave" at the top of the reservoir when it's half full, so I can monitor the water level. I plan to remove one fan from the CPU opt and connect it to the other header using a Y splitter, since the current fan isn't controllable. This should help keep the PC quiet when I'm not gaming.
