Actually, I'm into case fans again, you can spend money on a great CPU fan but if that hot discharged air from your CPU can't get out then it's null. Also I think people don't realize that other harware inside your PC also generates heat besides just the CPU and all this needs to be factored in when you select the type of cooling to fit your system. But keeping the inside of your system free from dust and blockage is the best and easiest thing to do.
