Thermaltake products are very successful. The Super-Orb and Mini-Super-Orb in particular. Be careful, if you are using a motherboard with a lot of capacitors around the CPU socket, the Super-Orb may not fit (ie KTA7A-RAID). I also read a review recently that suggested that the Volcano II may even be better than the Super or Mini-Super. Plus, it fits on a KT7A 🙂.
