Your 7700x with a SAMA AIO seems to handle idle temperatures well, staying between 60-65°C, but in-game it spikes up to about 75°C. Compared to your previous setup, the performance difference is noticeable. The fan curves haven’t been optimized enough for smoother idle temps. It doesn’t appear this model is inherently a weak AIO, but it may benefit from further tuning or a different model if you want consistent in-game temperatures.
When idle, your PC isn't actively working to lower the CPU temperature. The fans and pumps run at minimal speeds. Transitioning from idle to a light workload shows your cooling system is functioning well. In short, everything looks normal.
I had some doubts about the AIO since it's a more affordable 360mm cooler, and I wasn't sure if it was worth buying.
The temperature range of 60-65°C seems too high for your setup. Your 7900X with a 360mm AIO liquid cooler is usually around 45-50°C while idling. You might want to inspect the thermal paste and ensure the cooler is securely mounted, as improper pressure can affect cooling. Consider undervolting with PBO and using BIOS curve optimizer to reduce idle temps.
I'll confirm it once more, that was the first action I took when I observed the increased temperatures. Apart from the idle readings, everything else is functioning smoothly.
Have you tested its performance and seen how it stacks up against other sources? You might also want to explore undervolting with PBO and the curve optimizer in the BIOS—it can reduce idle temperature, perhaps you should also verify your pump speed; it should remain high during idle as long as it stays quiet.
I tested the system with the previous air cooler and used 3DMark for several tests. Temperatures reached about 90°C. I plan to run another test today after finishing the CPU work.
temperatures tend to stay near 90 due to the 7000 series increasing clocks until they reach a limit. This makes peak temperature a less reliable indicator of normal behavior. You might reach 90°C with clocks significantly throttled if the cooler isn't properly mounted. The best way to verify is checking benchmark results—ideally within 5-10% of your CPU’s average scores. Review your mounting guidelines to ensure everything is correct, then run a test and compare. Using HWiNFO can also help confirm core speeds stay close to boost rates under load.
The 7900X is sitting around 45-50°C. PBO is active with a -30 setting on the curve optimizer, which feels a bit too hot for idle temps, though it looks typical online.
