Heat will always win. You should try to blow out the inside of your computer or the fans on your laptop at least twice a year. The CPU inside your computer or laptop creates a lot of heat that has to be “pushed out” of the computer. If your heat sink or your fan is clogged then the computer will get too hot and you will end up shortening the life of your computer. If you placed two identical computers in two different rooms, one at 85 degrees and one at 65 degrees the “cooler” system will last twice as long as the “hot” system. We blow out every system that comes through Frankenstein Computers for repair, virus removal, data transfer, or anything else.
So, blow out your fans and keep those systems cool.
