How can you make a good heatsink even better? More heatpipes! AnandTech has run the forthcoming Thermalright Ultra-120 Extreme through its paces, and reports that the extra two heatpipes do improve performance measurably.
CoolerMaster took a different route with their GeminII. This monster heatsink is almost twice the size of any blow-down cooler we've seen before, and the widely spaced fins look promising for low noise and passive cooling. It's good to see yesteryear's prototypes finally hitting the store shelves.
If Novel Concepts can popularize "IsoSkin" , heatsinks in general may be a thing of the past. The material, a sort of planar heatpipe, could turn the outside of any computer into a highly efficient cooling surface.
