Thermaltake just keeps the innovations coming, not only a new heatsink, but a new ‘toolless’ retention clip.  Feast your eyes on the K450, brought to you by the folks at Techtastic.  This cooler performs, but as with most targeted at the A64, it is huge, weighing in at 438g, and with a fan it’s over 100mm tall.  If you have a tight fit in your case right now, maybe you should think about cutting out a blower!
“Today we take a look at Thermaltake’s K450 which is part of a new line of heat sinks developed by their advance engineering team ITBU. The K450 is design to work effectively with Opteron and Athlon 64 processors, and features a high powered fan and heat pipe technology.”
