We have all at some point of time faced the overheating of our laptops or desktop computers. On daily basis my HP Envy 17 3D and HP Envy 15 3D both hits the temperature @89-90 degree Celsius. The fan suddenly kicks into high-gear. And, when it hits 95 degree C, the laptop hibernates to save itself from burning.
These kind of heating issues not only hampers working, but is also risky, as the laptop might explode or if you're place the laptop on your lap, people can actually gotten burn.
The general issue of hot laptops is separate from those bad batteries, it becomes more visible in scorching heat; when your computer system starts working slower and then switches off for no apparent reason.
The heating could be due to a feature or the most obvious reason of heating is that over time dust and other particles clog the vents, fan and exhaust port or radiator of the system thus restricting the air flow and cooling. If it's dust or clogging, you can fix this easily by blowing out the vents and fan with air or using a brush.
Additionally, there are many other ways to fix temperature including additional fans, cooler pad, elevated stands, cooling mat, heat sink. These options may be costly for your and or not available in your region.
"If anyone is having a problem with their MacBook Pro getting too hot and not cooling down, try using some 10-yen coins you have lying around the house. The copper in the yen is a better conductor of heat than the aluminium of the computer and is good for getting the heat out."
To be honest, there's no guarantee that this technique is going to work for everyone, as it hasn't been proven. But the response online suggests, it's pretty successful for a lot of computer lovers out there.
So, why not give it a try, if your having access to copper coins.
