Omen 40L BeQuiet Pure Loop 2 120MM

I just bought a 40L and upgraded the CPU cooler to a Be Quiet Pure Loop 2 120MM. Install went smoothly but was trying to get verification on where the pump and fan need to be connected on the motherboard?

This video shows replacing liquid coolers on a 40L

Watch there the author connects the cables.

Let me know if the motherboard is different.

I was never able to find a motherboard viewer for the 40L, only the following models

Omen 25 30 25L 30L


HP 873-0000

Unfortunately it is a different motherboard in the 40L. I did find this image and the fan pins look the same as my board.

The top fan pinout is labeled fan/pump so the pump can go there.

normally the pump runs at max speed so you may need to monitor that fan speed to ensure it is at max 

I assume the Omen game hub shows fan speed but may not know that a pump is on it.. 

The bottom right show unused RGB power. 2 of the 3 "missing" are labeled GRB instead or RGB which is poor quality control but then it was not designed to have those pins and the control chips are not there anyway.

If your motherboard lacks 4 pin RGB power headers then consider a 12v rgb  hub

So I have the fan connected to the top left and the pump to the pump connector. The RGB is plugged into the hub on the backside. When running games the CPU gets up to 197F. I had to set the fans to manual mode where the fan will ramp up when CPU temps start rising. I have the pump set to max 5500. I feel it should be running cooler. I used Be Quite liquid metal thermal paste on both the cooler and the CPU too. The only other thing I can think of is maybe the radiator is not full?
