[Purdue] Tiny refrigerator taking shape to cool future computers - Page 3

post #21 of 26
Some newer Procs put out more heat then old ones
I mean shoot the real old ones didn't even need a cooler

The cooling technology used here might just be a heatsink. A piece of metal to conduct heat away. Eventually, the energy density will hit a point like .2w/mm^2 where the thermal conductivity of normal HS aren't enough. Therefore a heat pump to forcibly move the heat away (and increasing cooling) will be needed.
Oh, okay, I under stand now

Whats metric? Who uses that anyways.

Probably shouldn't of said that!

Alot of countries use it actually, not just America.

Uh... America is one of two or three countries that does not use the Metric system, the rest of the world does.
