Ok I wanted to give an update on this. I drained the fluids and redid the loop. Now it goes Pump > GPUs > Upper Rad > CPU > Front Rads > Reservoir. I replaced the XC7 CPU block with the newer one (M3 Gen 2) and used new coolant. I also added a couple thermaltake temp/flow monitors. Now my CPU runs at 35C idle and pops up to 55-60C when running a game. Bubbles are back in the CPU block so I gotta work those out, but overall am happy with the improvement. I'm guessing it was both the flow and the coolant which was roughly a year old. Replacing the CPU block might've been overkill but I didn't care at this point. Thank you everyone for the responses and advice.

There's definitely some air in the loop. I've been trying to get it out but it really is a pain. I mostly notice the bubbles in the outtake of the upper rad and some in the cpu block. I try tilting but this thing is really heavy. I also do have a custom curve. Sometimes I try cranking it to 4900 to try to get the air bubbles out. Should I take the cap off the reservoir to help remove the bubbles?

I dabbed on some paste and tried to make sure the 4 screws were the same pressure. Temp certainly shows better, but for idle I'd expect it still to be lower. I'm not overclocking so not sure why it's so hot. Here are two sensor shots at different vcpu

Ok I checked the mount on the back and I think it's good. The thermal paste however look light in two spots, almost like they were squeezed out.

Hello all, I have an issue where my CPU is running hot when idle. I installed a hydro x water loop system and am very new to doing this. Here's my setup: Obsidian 1000d case 1x XD5 pump/reservoir 1x XC7 CPU block 2x XG7 GPU blocks 2x XR7 480mm rads (front of case with 8 fans) 1x XR5 420mm rad (top of case w/3 fans) PC is powered with EVGA Supernova 1600 P2 80+ Platinum. CPU: Intel i9-9900k Pump goes to GPU blocks first, then to CPU, to the 420 rad, then to the 480 rads before back to the reservoir. As far as I can tell, my coolant temp is low but my CPU runs high and low loads or just doing nothing. I tried replacing the thermal paste with ARCTIC MX-4 - Thermal but that didn't help. I think the coolant if flowing well but I noticed there is usually an air pocket coming "out" of the 420mm rad. Not quite sure how to get rid of that and if that is the culprit to my problem. Anyone have a ideas? Here's what icue is showing me:
