PC worked great
For computer components, it is generally better to have low temperatures than high temperatures. However, everything is relative. One example: A Chinese enthusiast from Mohe tried to test how the PC performed on the streets when it was -53 degrees.
She built a computer based upon the Core i9-13900K, GeForce RTX 490 and GeForce RTX 490. Initial cooling was done with a liquid system, but it eventually froze and stopped functioning. Instead, a Noctua NH-1 passive cooler was installed. A fan array was also installed near the computer.
This resulted in the CPU temperature being between 10-15 and 30 degrees. It was easily overclocked to 6.18 GHz. Unloaded GPU temperature was -40 degrees, but it rose to 30 under load.
The computer remained cold for almost the entire night and worked well, even though the cables were frozen. You should also note that the original author built a PC with an Intel processor. This processor was only capable of heating up to 1-3°C without CO under load.
