Look up the Gelid SlimHero on Newegg. This is the cooler I got and it works surprisingly well for a slimline cooler. I don't know what type of motherboard you are using, but I put mine in my ITX build because of it's size. It's got a fully copper base, and the copper heat pipes do very well at moving heat. I get idle temps of 40-45c and load temps of 50-55c, which is pretty good for such an inexpensive cooler.
