Hello, I'm using a new rig that I made recently. This is my first time using liquid cooling, so it just be that I'm being dumb, but I have a Corsair Hydro X XD5 pump/reservoir combo that seems to be pumping yet temperatures are not being kept low and the little "water wheel" in the GPU block does not spin most of the time. Attached are pictures. Any help is appreciated. I know the pump works, since I have done a full fill and air bleed and 24+ hour test without issue; however, something is off and I'm not sure what. I've tried hooking it into the Commander Pro, the Water Pump slot on the motherboard, and disconnecting the fan control completely, none of which appear to fix the issue. If you need any other information, please let me know and I will attempt to provide such.

Thank you!

Welcome to the forums, newcomer!

To be frank, your tubing runs could be much more efficient by not having the tubes snaking around. You could cut down on the tube length as well as the outlet/inlets of the block on the GPU end. As for outlet and inlet, did you make sure to pay attention to the inlet and outlet of the block on the CPU, pump and the GPU? The GPU can be neglected but I'm fairly sure that the CPU block has a dedicated inlet port.

Make and model of your PSU?

I do realize that it is probably not the most efficient tubing--and if that is a cause of the issue I'll replumb if I need to....it's just a fair bit of work to do so. As far as the GPU and CPU blocks, I could not find anything in the online manual suggesting the GPU block has a dedicated inlet and outlet port. The CPU block does, but I followed the instructions to make sure that the inlet and outlet ports should be correctly plumbed from the outlet of the pump.

The PSU is the Thermaltake Toughpower Grand RGB 1200W 80+ Platinum Smart Zero RGB Fan.

Well, I've replumbed the tubing to be more efficient and limit any extra, unnecessary length, but it still does not seem to be going through the GPU block and still having idle temperatures around 30-31 Celsius. The "water wheel" in the GPU block still is not spinning, so I'm not sure. If anyone else has any recommendations, please let me know!

The wheel is a flow indicator, but those can become sticky and not rotate as well.

Just to confirm, the pump outlet is going.....where? And CPU block inlet/outlet are defined ? Normally, CPU blocks are uni-directional, and coolant must flow a specific direction to function correctly. Also, can you confirm the pump inlet and outlet are correctly defined for overall loop flow?

What are your CPU and GPU temps under load?

Ok, I wasn't sure how much that was truly indicative of flow, since it usually seems to run for a little bit at boot up and then stop. I had assumed that if liquid was flowing through the GPU block it would kind of have to spin.

The pump outlet is going to the CPU, then GPU, the radiator, and back to the pump/reservoir. The CPU block inlet and outlet are correctly set-up according to the manufacturer's instructions. Yes, I followed both the written and video instructions because I wanted to make sure that I used the correct port on the pump for the outlet and one of the appropriate inlets.

Doing a test of Cyberpunk 2077 for about 15 minutes, the CPU average temperature seemed to be about 45-47 degrees Celsius and the GPU average temperature seemed to be about 40 degrees Celsius, which is the first time I've done much of any real load, since I didn't want to overstress it before making sure everything was fine. I also realize that I had been just referencing the LED display on my motherboard that displays the CPU temperature while running; however, using Corsair's iCUE shows both the CPU and GPU temperatures and the CPU temp there reads a few degrees lower than the motherboard display as well.
