As the days grow longer and the temperatures start to rise, your computer may have trouble keeping cool – especially if you run a lot of performance intensive tasks like gaming or video editing.
If you don’t want to invest in new, high-powered case fans, or clean out the dust clogging the interior of your case, then there is one thing you can do: open up your case and put a regular fan beside it. This will circulate a large amount of cool air through your case while allowing hot air to freely flow out. Most room fans are significantly larger than anything found on your PC case, which means that they will do a much more efficient job of cooling down your components.
 
This trick works well in a pinch, but it’s not a great long-term solution. Dust will accumulate inside your case much faster than it normally would, and having your PC open like that will undoubtedly lead to problems. Your cat could climb into the case, for example, or you might spill a glass of water nearby and have a droplet land on your motherboard, creating a short circuit.

A far more effective long-term solution is to install good optimization software on your PC. This will smooth out your PC’s performance, meaning that it doesn’t have to work as hard to run even the most performance-intensive applications. If you have extreme overheating problems, then installing software like this might not fix the problem completely. However, it is a great way to get started.
Regardless of which method you choose, it’s important to remember that an overheated PC can be very dangerous. Your parts could literally melt, releasing toxic fumes and permanently damaging your computer. At the very least, your computer will crash, slow down, and freeze, which is why it’s a good idea to solve your overheating problem sooner, rather than later.
