CPU Usage Causing Overheating

Some applications require a higher CPU usage which tends to increase the temperature of the MacBook. How can you find out which applications use the most CPU?

Dirt and Dust Causing Overheating

Often, overheating is a result of dust collecting in the laptop's heat sinks . When the laptop starts to heat up, the fan has to work harder to cool it down. This also means that the dust is blown around more and, unless you regularly clean your laptop, it could build up and clog your heat sinks, i.e. the cooling system. See if your MacBook performance improves and cools down after you've given it a good clean.

Manually Control Fans to Prevent your Macbook Overheating

Another way to fix this is to manually turn on the fans. MacBooks perform fairly well without manual intervention but, if you're about to run some applications you know will cause it to overheat, this manual feature can be useful. Programs like smcFanControl let you decide when and how fast the fans should run.

Once you have this information you can monitor the CPU temperature - you should make sure it never exceeds 60ºC.
