Spire SP507B7-U DiamondCool heatsink
 

Heatpipe based heatsinks are the latest rage in air-cooling today. The method of using heatpipes is not new, but is becoming more and more perfected. Due to the fact that this technology works quite well, some manufacturers have released some really big coolers. At the same time, some of these coolers presents issues with mounting to some motherboards. This is not the case with the Spire DiamondCool heatsink. It is small enough to fit on any socket 775 motherboard.
