The thermals rise quickly because warm air near the ground becomes less dense, causing it to ascend rapidly.

Your PC is overheating quickly, dropping from 40°C to 90°C and then returning fast. This suggests thermal management issues. Check if the cooler is properly seated, clean dust from vents, ensure fans spin smoothly, and verify the CPU cooler is functioning correctly. Also, confirm the motherboard supports AIO cooling and that temperatures are monitored accurately.
I think the cooling system might not be properly secured. It could be touching just a part of the heat spreader due to insufficient mounting force. Have you considered reattaching it?
This was my first impression, yet in the video the temperatures only decrease once the load stops. If there were spikes followed by drops while the load remained active, I would concur. This pattern is quite typical, but it doesn’t match what I observed.
The problem lies in the small contact area and heat dissipation, not related to pump speed, coolant temperature or fan rotation. I can replicate this same effect on my 3100 model. The pump runs at full capacity, yet fans only slightly adjust to maintain temperatures. It can take 3-4 minutes for temperatures to decrease noticeably from peak levels.
It’s typical for the die to heat up right away and stay that way during testing. As heat moves through the die, IHS, cold plate, and into the water, the system reaches a stable temperature and the cores gradually warm up. Once steady state is achieved, the maximum amount of heat can pass through the die, IHS, and cold plate, allowing the radiator to release it into the air and keeping the temperature stable. When the workload stops, temperatures inside the CPU drop quickly, while the water stays warm for a short time before the radiator starts cooling it down. As the water cools, the CPU core temperature also decreases slightly because warm water doesn’t transfer heat as effectively from the outside. This behavior is normal. Are you running an overclock? Which benchmark are you using? High loads like prime95 can generate excessive heat beyond normal levels.
