CPU and AIO concern after gaming

So I just ran a game of call of duty warzone, and everything seemed fine. HOwever I closed the game and about 5mins later checked that my radiator fan was running still pretty fast. CPU temperature is still kind of high. Is this normal after even couple minutes of closing game

Coolant temp seems normal for post gaming. That 36-37C coolant temp is also the minimum possible CPU temp if your Vcore was zero. Voltage is never zero unless you are shutdown or in sleep, so you typically ride above it. What's changed in the last several generations for both AMD and Intel is you no longer sit flat at 600 Mhz when at idle. Minimum frequency is up and it reacts more quickly to even the lightest of loads. That keeps the Vcore up at higher levels in the idle state and the result is your idle temps are higher. The coolant to CPU differential is 14C, so if you had just booted up in the morning, you would be around 20C coolant and 34 CPU temp. That probably would not cause any alarms.

after a couple of minutes yes it's perfectly normal. It takes some time to cool down the water. Same goes for custom loop.

 

That said, your custom profile is not applied to the fans, i hope that's intentional :)

Okay thank you!

So the temperature showing on icue is not the cpu temperature right? Reason I'm asking is because I tried this again on custom loop setting it to so that the fans speed up as the cpu gets hotter, but it was slow to do so. Because so through MSI after burn my temperature was showing around 60-66 degrees Celsius and the fans weren't pick up right away

The temperature to the right of that lovely pink square is the coolant or liquid temperature. It is the baseline or lowest possible CPU temperature. The cooler works by conducting heat from the CPU, then the liquid system acts like a waste heat containment and disposal unit. Watts in vs watts released through the radiator and fans. It can hold quite a lot, but each +1C in coolant temperature also means +1C in CPU temp. Your pump and fan speed will affect the coolant temp directly and the CPU temp indirectly.

 

The coolant temp is also the measure of efficiency for the unit. If there is a problem with the cooler, the coolant temp will get very warm. If CPU temp is hot but the coolant is normal, you need to look for the issue in another place. Typical coolant temp range goes from a few degrees above your room temp at idle (or case ambient temp) up to about 6-10C above the baseline during load. A 5600x is an efficient processor with a low TDP. It alone won't put a lot of heat into the cooler. However, you are still bound by the environment so when the case interior heats up from the GPU, it takes the CPU along for the ride. This is true in air cooled systems as well, but it's not as obvious without the liquid temp data to show it to you.

 

Keep your custom curve using the H150i Temp in the sensor setting (liquid temperature). That is the proper control variable. Letting them run by CPU temp is like setting your air conditioner to run based on the sun's intensity outside, not the temperature in the room you are trying to control.
