The water cooling pump isn't moving the coolant.
The water cooling pump isn't moving the coolant.
After spending a lot of time as a PC enthusiast, I finally chose to install hardline tubing into my watercooling setup. Everything worked smoothly until I added the fluid to my reservoir. I'm using a D5 pump, and when I turn on the system, the pump starts clearly (it hums and makes ripples in the coolant), but it doesn't seem to be directing the coolant to any other parts of the system. I'm unsure what's going wrong and appreciate anyone who can help.
Verify the pins on the Molex plug for the pump, ensuring they are properly reinserted and making good contact. On my previous D5 model, I had to repair this issue since the pins didn't sit well. If the pump was functioning and producing noise and turbulence, it indicates power was being delivered. Even if damage occurred, some sound would still be audible. This suggests a possible problem with the power connection. Would you like me to check that?
What device is connected to the pump, and is it receiving sufficient power? If you connect it to a motherboard fan header, verify that the voltage is increased. Otherwise, the pump might be faulty.
What is your loop order? Sounds like you have an issue with an airlock in the loop and the pump cannot move coolant. Does the loop have the reservoir cap open so that the coolant can displace the air and move the coolant?
What device is your pump connected to, and is it receiving sufficient power? If you connect it to a motherboard fan header, make sure the voltage is increased. Otherwise, the pump might be faulty. My pump uses a molex and fan header on the motherboard. How can I adjust the voltage?

It seems it's connected to a 4-pin molex and a fan header. You only need one. Molex will maintain full RPM continuously, and if it's on the board, you can use the BIOS to modify the speed of that header.

No, from what he shared, this isn't the problem. Also, the D5 pumps don't use a motherboard header—they're Molex. This isn't a closed loop cooler.

It seems it's connected to a 4-pin Molex and a fan header. The pump I have is an EK D5 PWM model.

Yeah, I didn't notice it was a d5 pump. As Rubix mentioned, there should be a way for air to exit the loop so the fluid can be refreshed.
