[Purdue] Tiny refrigerator taking shape to cool future computers

Researchers at Purdue University are developing a miniature refrigeration system small enough to fit inside laptops and personal computers, a cooling technology that would boost performance while shrinking the size of computers.
Quote:
"We feel we have a very good handle on this technology now, but there still are difficulties in implementing it in practical applications," said Garimella, director of the Cooling Technologies Research Center based at Purdue. "One challenge is that it's difficult to make a compressor really small that runs efficiently and reliably."
Quote:
New types of cooling systems will be needed for future computer chips that will likely generate 10 times more heat than today's microprocessors, especially in small "hot spots," Garimella said.

With every process shrink we are using less voltage and giving off less heat while still increasing performance. This article is a bunch of liaz.

Duh? That's the only thing keeping it from happening. Captain Obvious?

Nope. With every process shrink and generation of CPUs, we are using more transistors per given area. While the transistors are more efficent, the thermal density is increasing over all. The decreased surface area while increase heat makes it harder to cool.

i.e. 100w over 1000mm^2 vs 65w over 300mm^2

Yeah.... thats what I want.. the added weight and energy draw of a compressor in my laptop lol

That depends on what happens when we start getting ridiculous with the number of cores we have, and graphics cards still produce a lot of heat.

Maybe work on designing chips better and not ridiculous cooling solutions?

GPUs produce a lot of heat because they have so much stuff packed into the smallest area possible. Plus the most advanced process is the 55nm by TSMC. Once we go to HKMG 45nm, GPU heat will go down dramatically. The number of cores also won't effect us that much because HyperThreading is coming back, that means you don't need as many cores to have as many threads

i wish intel made NV's chips in 45 hi-k
actually i think intel should just buy NV, but i guess they have reasons not to.

Now people will be asking, can i put a refrigerator inside my computer and not can i put my computer inside a refrigerator??
Cool technology, definitely. no pun intended. I wonder when it is available to the consumer how effective it will be, looks still a year or 2 off at least IMHO though.
