I was told that my PC is a little too hot inside, it runs about 50 to 53 idle or when I visit websites like this, and when I play WOW it runs up to 58°C or higher. I was suggested to clean out the dust from my PC. I know to take the plug out of the wall, but how do I remove the dust? Do I need can of air?
Also is it safe to leave the side of my PC open and have a fan blow inside?
