What is the optimal degree for CPU?
It looks like your CPU is operating within a normal temperature range, staying between 35-36°C at low load and 54-55°C under higher load. Since you've already updated the thermal paste and cleaned the cooler, and your case lacks fans, upgrading to case fans in the future should help maintain stability. It should be fine as long as the cooling solution remains effective.
It’s not about a single perfect temperature; it depends on your environment and cooling setup. Running at 55°C with minimal load feels high, but under full load it can rise significantly. Most CPUs use fans to manage heat, while passive coolers rely on ambient conditions.
Sorry, but I wouldn't agree with that. It could be a genuine point, though I think no one here would like their CPU running at full capacity under regular use. If your processor reaches its maximum speed, it's likely exceeding it and will slow down to manage temperatures.
You should aim for a consistent temperature around 85°C. This reduces fan usage while still preventing overheating of the motherboard's circuitry.
I tend to aim for lower temperatures, but if that's not feasible I'm okay with the CPU operating at that temperature. Probably related to my OC tweaks since higher frequency and voltage cause more heat, which can lead to instability if the CPU gets too hot. On newer 13th generation chips like the 13900K, it's expected to run around 100°C, and you really can't do much about it unless you're willing to sacrifice performance.
It varies with the surrounding temperature, but as long as you keep it under or at 80°C during peak use and around 20°C when running lightly, it should work fine.
There are two main ways to harm a CPU through heat: overheating and temperature changes. Extremely high temperatures definitely cause damage, but I believe prolonged operation at a high temperature like TJ Max will lead to wear and shorten the chip's life. Thermal cycling also poses risks, though frequent shifts between 40° and 70° might not significantly affect longevity; shifting from 20° to 100° likely will. Materials in the die expand and contract differently, eventually leading to issues. It’s unclear whether a chip needs to be replaced before it becomes too unreliable, but I rarely encounter failures and keep my computers running even when away from home.
The temperature remains between 60-70°C under full load. The stock Intel cooler includes a fan for cooling.
