7700x 120 degrees
Dear Community, I didn’t succeed this time. Earlier I discussed assembling a new PC for a friend. The configuration included: MB Aorus b650, 6000 MHz RAM, 32 GB GPU, 7900 XT CPU, 7700X CPU cooler, AIO deepcool LS720, and 850W case fan. After finishing, I installed Windows 10 and only updated it with the updater. The fans were spinning fast, so I wondered if the issue was with the cooler or the case fans. I remembered a previous build two years ago with a noisy fan; I adjusted speeds using software to lower them gradually. At that time, it was late, had a lot on my plate, and a newborn baby meant limited time for building. I left the pump and other fans running at low speed while I ran benchmarks, and hwmonitor was active in the background. Two minutes earlier, the CPU temperature reached 119–123°C. I stopped the fan controller program immediately; the fans kept high, cooling the CPU back to 70–90°C. The benchmark showed poor performance—likely due to overheating. I couldn’t run another test with fans on auto, but temps stayed between 70–80°C, peaking at 91°C for a brief moment.
I’m concerned this might cause hidden damage that only appears later. Should I replace the cooler or the system?
Or if no damage occurred, will it still function properly in the long run?
Why didn’t the computer shut down despite such high temps?
What steps should I take to ensure my friend’s PC remains reliable for 5–10 years? Should I upgrade parts, repaint the cooler, or replace everything?
I’m really sorry for this mistake. I’m hoping you can help me decide what to do next.
Userbenchmark shows poor accuracy. Try running a cinebench test to check consistency. Keep the AIO speed near 80% for optimal efficiency and lifespan. The radiator above the pump works fine. 91C is warm enough, though it won’t perform well with that model. What radiator did you install?
Have you verified the AIO setup? It’s best to test the benchmark at regular fan speeds; silence indicates proper installation. You can operate fans at low speeds, but avoid adjusting pump speed. Ensure the cooler is securely mounted and consider reapplying thermal paste if needed.
It seems there might be an issue with the sensor or software causing instability. Your CPU isn't reaching 120°C. Test with different programs such as RTSS or HWInfo64. It appears the system is showing double values, likely around 60°C.
