I'm using the default stock cooler, I clean my computer constantly, I often use it for gaming, Never needed to look for an aftermarket before though. Although no there is not good airflow throughout the case, I only have $140 to spend right now though. I only have one fan in the back sucking air in, should I get another case? Aftermarket Heatsink? Or both? The current way I have my desktop case and how I like it, it could only get air through the front and top, not the back very well. If its a case problem wouldn't my idle temps be bad as well? Any suggestions?
