Researchers cool CPUs with nano-size fridges
Temperature has become an issue for CPU development for a while. Heat has the potency of shortening the lifespan of the chip by changing the property of the transistors; excessive heat can even cause the chip to burn. As companies like Intel scale down the size of CPU and increasing the number of transistors, more and more electrons are crammed into a smaller and smaller space, and increase the clocking frequency, more electrons transferred per unit time, the temperature of the CPU gets higher and higher. As a result, Intel and other companies stop increasing the clocking speed of a single core and move onto multicore processors. In order to overcome this issue, these companies are currently introducing nano-size fridges into the market of cooling for CPU.

The current air cooling devices, such as heat sink and fan, are not capable of cooling something above a hundred degree Celsius and are pretty loud, and the current liquid cooling devices, such as water cooling or even liquid nitrogen cooling, are too massive, expensive, and power drain. Nano-size fridge, however can be incorporated into the CPU and offer low cost, low noise, and low energy consumption. In addition, these nano-size fridges are there to complement the current cooling devices, where they are placed in the 'hot spot' of the CPU, such as the core die or the back part.

This nano-size refrigerator will be on the scale of 10 microns. Unlike conventional macro fridges, which are made with mechanical heat pump and liquid coolant, the nano-fridges are made with thermoelectric molecules, ie. Bismuth telluride and Antimony telluride. One special property of thermoelectric molecules is that they are capable of converting thermo energy into electricity; in other words, "you're using electrons to pump heat away," said researcher Venkatasubramanian. With the aid of excellent thermo conducting nano materials such as carbon nanotubes, these freezer can decrease the CPU up to 40 degrees Celsius, which will greatly lift off the work load of large cooling devices.

and you all know what it means... HIGHER CLOCK SPEEEEEEEEED!!!!

Note this nano fridge is 'an addition', it cools off extra 40C on top of others.
@dim
the ATI FirePro™ V8700 seems pretty hot for workstation card :wub:
