I'm looking for a heatsink that will perform better than intel's stock heatsink while maintaining the small size. The CPU I have is a Intel Pentium G620. I would like to be able to have my system very quiet. Unfortunately the case I built for it was planned out very well in pretty much all aspects except the cooling. Right now I have only got the CPU fan and two small 50mm fans exhausting out the back. I dont have room for anything else. It isn't doing too bad the way it is, but I'd like to be able to have the fans running as slow as possible, or atleast so they are quiet. Maybe I need better 50mm fans. I just got cheap startech.com ones. Any ideas on a heatsink that will give better performance and not be louder or much bigger would be great.
