* Newer, better Heatsinks

Overclockers rejoice - refrigerator-style heatsinks may be coming quicker than you think.
Purdue's heatsinks work like refrigerator coils. Cool liquid circulates toward a hot spot, absorbs heat, and then leaves, only to circulate back after a trip through a compressor. (Using a similar technology but in a very different way, Boston Microsystems has created a chip with microchannels that can heat up to 1,100 Celsius in 1/1,000th of a second.) One of the challenges in the Purdue project was that materials behave differently inside a small device. Fluids flow differently in microchannels than they do in larger tubing, and bubbles form differently, which changes how heat is dissipated.
The days of the fan-based heatsink might be coming to a close if this technology gets affordable.
