How Do I Prevent CPU Overheating

CPU Overheating occurs due to temperature issues. If the temperature varies in the CPU, it is ideally an indication of damage to the processor. It can also violate the performance on other hardware’s of the computer system.
Symptoms of CPU overheating:

  • System reboots frequently
  • Performance of system slows down
  • Gets hung or locks
  • System collapses

Ideal CPU temperature:
Commonly, CPU temperatures are within 70 degrees Celsius. Users must be aware of their CPU temperature. Temperature varies with make and model of processors. The stats below will give you a fair idea of process maximum temperatures:

Reasons behind CPU Overheating:

  • Installation issues of Heatsink in CPU, resulting in incorrect contact with CPU and the heatsink. Application of proper thermal grease will take care of heat generated by CPU. Improper grease application might cause excess heat resulting in CPU overheating
  • Dirt on CPU fan leads to broken power supply result CPU Overheating
  • Improper maintenance of air flow in case. Dust blocks and disturbs air flow

Remedies to overcome CPU overheating:

  • Check if CPU fans are running efficiently, if there is dust accumulated, clean CPU fans periodically.
  • Store systems in normal temperature areas, not very hot devices working next to it
  • Shut down system for some time till it cools.
  • Pins connected to CPU should be up to the mark.
  • Take professional Hardware technician support.
