In general, 80 degrees Celsius is considered hot for a CPU (Central Processing Unit). While CPUs can handle higher temperatures, sustained temperatures around 80 degrees Celsius or above can potentially impact the performance and lifespan of the processor.
Modern CPUs often have a maximum temperature specification known as the "TjMax" or "TjMax Temperature." This value represents the highest temperature at which the CPU can operate safely. For many consumer-grade CPUs, this value is typically around 90-100 degrees Celsius. However, it's important to note that running a CPU at or near its maximum temperature for extended periods can lead to thermal throttling, which can cause performance degradation.
Ideally, it is recommended to keep the CPU temperatures lower to ensure optimal performance and longevity. Most CPU manufacturers recommend operating temperatures below 70-80 degrees Celsius under heavy load conditions. It is common for users to utilize cooling solutions such as heatsinks, fans, or liquid cooling systems to dissipate heat efficiently and keep temperatures within acceptable ranges.
Monitoring CPU temperatures using software utilities or accessing BIOS/UEFI settings can help you keep track of the temperatures and ensure they remain within safe limits. If you consistently experience high temperatures, it may be worth considering improving the cooling system, cleaning the cooling components, or reapplying thermal paste between the CPU and the heatsink to improve heat transfer.
