EK D5 water pump.

I recently built my first custom water cooled pc. Each time I booted it up I could visually see the water in the pump and hear it as the pc struck up and entered into normal running mode.

Recently I have noticed that this isn't happening anymore (no more air bubbles or water turbulence) and my system will sit at the same temps as it did when I first built it, but there is no sound or any kind of visual clues from the pump to say it is working. Running temps after 3 hours of intense VR gaming are at 40 to 45 degrees C and idle temps are 25 to 30 degrees C.

The CPU is a Ryzen Threadripper 2950X and the GFX which is also in the same loop is a RX Vega 64, all connected to a 3 fan radiator.

If the pump wasn't working would my temps be higher than what I am seeing?

As a side note I am going to buy a visual indicator to add to the loop so I have some visual clue to if it is working other than guessing at it due to temperatures.

Any advice would be appreciated.

If your pump was dead your temps would rocket pretty quickly, especially under load. Is your pump connected to a fan header on your motherboard? You should be able to see the pump rpm through that, and also enable the cpu fan failure warning if you wish to warn you or shut down the system if the pump was to fail.

What’s happened is your loop has now bled all the air bubbles out of it.

Enjoy the silence!

Visual indicators can be hit and miss, sometimes they can be a bit noisy. Modern CPUs have thermal protection so I wouldn’t look to add one myself.

Welcome to the world of silent PC operation lol! D5's are virtually silent when the system has rid itself of air. As mentioned, if there was anything wrong with it, your temps would be going through the roof under load, you'd be throttling and likely the system would crash... but with the temps you're reporting, you clearly have nothing to worry about.

Thank you all for the quick replies. It is a huge relief to hear confirmation on this. I will check the BIOS and the pump header connection to the motherboard.
All this is a new learning experience for me on this side of PC building.
