Heatsink complications leading to PC overheat

Asked By 360 points N/A Posted on -

I have been experiencing a series of problems with my PC. Two days ago, It was crashing to blue screens every 5 seconds and the fun was making strange loud noise. I opened the casing and did a thorough cleaning, the heat sink and the processor, which covered by most of the dust. The blue screen problem was solved. I then installed a new fun, Rose will cooler “max 3.4 GHz, but the fun still made the same noise and it would refuse to boot.

Yesterday, i found out that the fun on the heat sink was dead. To prevent the overheating, i had to change the computers performance to ” power saver mode”. It would then record a temperature reading of about 60°C on Asus' thermal monitor. On Real Temp's monitor , it recorded a reading of about 50°C The temperature readings are constant, and do not depend on the number of programs being run or the task being carried out.

From what i know, excessive heat for computers is not recommended and may lead to serious system’s components damage, so i rarely use the computer. Right now i have no option of replacing the motherboard it could be the problem. Could the power system be the problem? Or the CPU connector to the fun? Any ideas of what could be the problem? I need your help guys!

Heatsink complications leading to PC overheat


Hi Joseph Hills,

  • I read you post and try to imagine what happen to your pc. I had ten experience in troubleshooting and repair of computers and seems your problem is within the CPU/Processor heat sink and fan.
  • Because once, the Processor is overheated computer will automatically shutdown and if this will continue it will lead to burning the processor.


  1. You had clean the fan of the heat sink but the problems occurred again. Remove the fan and the heat sink. Clean the fan and the heat sink including the bottom part, the one in contact with the CPU or Processor
  2. Put a CPU paste between the heat sink the CPU. Do not the remove the CPU if you don't have experience in doing it. That might cause problem.
  3. In putting the paste, see to it that there is sufficient contact between the heat sink and the processor in order heat transfer from the Processor to the heat sink.
  4. Then assemble again the heat sink. I hope this will work.

Check your power supply’s performance, and the cables which are connected with fan and the Motherboard. When the time passes the performance of a power supply could change. The heat sink system has been designed to increase the RPM of the fan according to the increase of the temperature.

If there is any problem in the power supply, fan also will not work properly. Processor will stop due to higher temperature.
