Quite a revelation with these discoveries. I change the GPU profile from 'performance' to 'adaptive' and I am seeing decreased temp: CPU: 42C~ Coolant: 34C~ GPU: 42C~ The GPU originally was 55C on idle now dropped to 42C wow. With all these testing, is this normal behavior based on the limitation of the airflow of the case?

Top is the exhaust point, the left and right are basically perforated like you said. Gpu on one side and CPU on the other. The bottom of the case is elevated so I assume that's where the intake of fresh air is with some possibility of side. The sides have no fans attached. Based on https://www.techpowerup.com/forums/threads/ryzen-9-3900x-voltage-and-temperature.257295/ I have set the voltage to be 1.25v. I am getting 46C/47C idle on CPU now and coolant is around 37C/38C.. seems just slightly better. I have also taken out the top cover so radiator exhaust is completely unobstructed. In the R20 test, I only tested the multi-core of the CPU, no GPU at all. I wonder though if the GPU 55C heat rises into the fan/radiator contributes to upping the radiant idle temp. Setting the profile of the H100i Pro to quiet, the fan noise is doable at idle, for gaming, it is bearable. The question then is 40C/45C bad for radiator an hour or two a day? What I could also test my system without any panels (left, right, top) and see if the temp improves. But in reality, without any external factors, the radiator should be sitting slightly over ambient right?

With a single cinebench r20: CPU: 83C, back to 45C Coolant: 38C, went back down to 36C with balanced settings after a few min. Ran some games for 20min and got: CPU: 60C Coolant: 40C ~ 45C Is 40/45C ok for radiators/coolants?

Hey thanks for responding. H100i Pro is mounted on the top of the case exhausting air out. The fans are below the radiator blowing towards it and out of the case. I have the https://louqe.com/ S1 case and it does have thin panel which I can try without. The MB and GPU sits below the radiator/fan on the bottom. Seems natural the air from gpu or cpu can rise and affect the radiator temp. I doubted myself about applying thermals correctly so I had it redone and making sure they are tight. The cables are tied up better as well. Here are the temp I have after 5/10 minutes after cold boot: CPU (3900x): 43C ~ 46C Coolant: 30C boot, climbed and hovers around 35C ~ 36C Seems to be about the same. :/ Good to know there are conflicting applications. Measurements are only taking with X1 precision, Ryzen Master, and iCUE. I used HWiNFO on the last take. I'll make sure of that. Is it possible that the case and lack of airflow had made these temps creep up over the average idle temp? Also did some research that some motherboards gives high default voltage 1.4+ vs the 3900x stock 1.2. I haven't messed with any of the motherboard settings though.

Did 4 cinebench r20 at load testing and got: CPU: 80~82C Coolant: 40C After a minute rest: CPU: 48C trending down Coolant: 39C trending down

Pump cycling a few times and the coolant temp went from 33C to 31C. After that I have set the fans to be fixed 1,100 RPM and the coolant temp seems to hover around 31C and slowly climbed to 33C. I have this fitted into a small form factor pc. I had to contort the pipes slightly to get it fit. Is it possible that this might cause obstruction thus giving these readings?

First of all, thank you so much for giving me insight. I spent hours trying to figure out why my new build sounds like a jet engine. This will help me tremendously trying to narrow down the issue. So here are the temperature readings from this morning. The room temperature is 20C. Computer Cold Boot: CPU: 36C ~ 38C Coolant: 25C 5Min In: CPU: 38C ~ 40C Coolant: 28C 10Min In: CPU: 42C ~ 44C Coolant: 33C 15Min In: CPU: 42C ~ 45C Coolant: 33C Motherboard: 46C, 61C, 21C, 42C, 51C Drives: 44C, 33C, GPU: 55C The temp seems to be hovering around the last set of values afterwards. I will try to cycle the pumps next.

Also, am I suppose to hear pump? I have pump turned to extreme with 2910 RPM and I don't hear anything.

I have a Ryzen 3900x with the H100i Pro AIO. My idle temperature is sitting at: CPU: 47C ~ H100i: 38C ~ Does this look right? I have the fan profile set to 'quiet' and the fan spins up almost immediately to 2000+ RPM which is super loud. I am concerned whether this is normal idle temp for the combo or H100i in general.
