How To Diagnose PC Overheating Problem.

PC Overheating Problem.

Computer components are designed to work within specific tolerances, with limits on humidity, altitude, pressure, and temperature. If your PC gets too hot, it will sometimes throttle the speed of the processor. Adequate cooling is therefore vital to the smooth functioning of any PC and, ideally, you want to keep your processor at around 80C or lower. You can check how hot yours is running with HWinfo, which is free to download from www.hwinfo.com

HWinfo

Click Sensors on the toolbar and, in the Window that opens, scroll down to the processor temperatures, which show the heat level within each core. If they are running hot, power down your computer and, if you’re using a PC with a removable case, carefully unlatch the cover and use the nozzle of a vacuum cleaner running on low power to suck away dust from the case vents, fans and accessible parts of the motherboard. Avoid placing the nozzle directly onto any components and resist the urge to blow stubborn fluff balls or dislodge them using a pen, pencil or finger-a soft brush is acceptable.

If you’re using a laptop, accessing internal components is more difficult, but you can still vacuum external vents to improve airflow. Also consider vacuuming your laptop’s keyboard to unclog any debris, because the gaps between the keys can help heat escape.

Once you’ve reassembled and rebooted your PC (don’t run it with the cover off because this can impact directional airflow), check in with HWinfo again. If the processor temperature is still high, consider replacing the thermal paste between your processor and its dedicated heatsink. The processor involves unclipping the processor’s dedicated fan from the motherboard or heatsink (a finned metal radiator), then removing the heatsink from the processor itself. This should be done very carefully because the heatsink and processor will be attached to one another by the existing thermal paste. Keep the processor in its socket if possible and, if it does come free, take care not to damage any of its pins.

Once you’ve separated the heatsink and processor, use rubbing alcohol to remove the existing thermal paste from both components, then apply a fresh layer of paste. There are several types available - Arctic Silver and Thermal Grizzly frequency get favorable reports in online reviews. It’s important to use neither too little nor too much paste to avoid either burn out or leakage when the two components are sandwiched back together.
