Didn't know which section to put this in so I figured this was kind of an all-in-one type of forum. I moved my pc into a corsair air 540 recently and have been hearing some little cracks/noises. I think that it is just the case plastic expanding due to heat, there is a lot of heat in my case since I don't have a graphics card with a blower, it has two fans blowing air inside of the case. I don't know if that is what is really going on but I just wanted to ask here to make sure.
