The easiest way to prevent your computer from overheating is by simply keeping the fan free from dust. You can blow out a lot of the dust by using a can of compressed air. Think it can't be that simple? Think I am full of it? Read on.
About a year and a half after I bought a new laptop, I noticed every once in a while, it would get real hot then shut down. It would only happen if I was ripping or encoding a CD or DVD. After another year, it started happening more frequently. I thought it was because I was using bad programs, or because of my operating system (I didn't remember it happening in Windows XP, it only happened in Ubuntu Linux. I think this is because I never use Windows though) or something that was using too much processing power. After a while, I started monitoring the temperature on my computer and noticed that it was running about 150-160 degrees F without me running any programs. Once I would do something a bit process intensive (sometimes just opening up my browser with a lot of tabs) the temperature would go up to about 200 degrees and my computer would shut down.
Before taking my computer somewhere to get checked, I finally decided I would buy a can of compressed air and see if I could clean up my computer again.
|Compressed air cans can be bought at just about any computer store or large supermarket (unless you are in China... then it is surprisingly difficult to find).|
Before you clean out the dust, make sure you turn your computer off. I like to start from one side and go to every slot and spray the air. You will probably hear the fan spin quite fast.
Be prepared to see a lot of dust come out if you have not cleaned it before. I generally don't spray for too long, just short bursts to get the dust out. I go back and forth to each slot until dust no longer comes out.
This obviously will not get ALL the dust out, but it is a cheap and easy solution to keep your computer a bit cleaner and keep the temperature down. If you keep your laptop regularly in the same spot, it might be a good idea to get a cooling pad and keep your laptop on that.
