Asetek's Extreme CPU Cooler Tested

But as with anything like this, there is always a turn key solution brought to market you can buy. Enter asetek, and their VapoChill series of Phase Change Cooling systems. What we have on the review bench here specifically is the asetek VapoChill Lightspeed [AC], a case separate enclosure containing a Phase Change Cooling system for your PC's CPU."

Apply the cold side to the CPU, and vent the hot side outside the system case. The danger here is to create a way to preveent the engine from being run in reverse, as if the electric motor isn't powered for some reason, the engine will start running off the CPU's heat, rotating the electric motor, creating electricity.

      Which is, of course, something else you could purposefully do. A sterling engine could be used to utilize the heat dissipated from a CPU or GPU in order to generate rotational movement, which could then be converted into electricity. Add a battery to store the charge, and you could probably run a diskette drive, hard drive, or CD/DVD drive completely off the waste heat from your CPU (with the big downside being you don't wind up providing a whole lot of cooling capacity to the CPU itself this way).

      Neither of the two Thermalright coolers you (brokenly) linked to are peltiers. They're just massive surface area heat-sinks with heatpipes and fan mounts.

      Thermaltake makes a peltier cooler. I tried it when I first built my P4 system about 18 months ago. It was abysmal. The controller would let the CPU run up to almost the published thermal limit (65C+) and then kick into high-gear. The fans ramped up to an unacceptable noise level and the peltier started making this loud click-click-click sound.

      Granted, the temps went down to about 36C amazingly fast. At that point, though, the cooling system went back into it's quiet state and the temps would start creeping back up again.

      I switched it out for a much simpler, quieter, and far less expensive Zalman 7000. My CPU temp runs consistantly within a range of 38-40C now. Maybe a bit higher under heavy gaming load, but not 20-25C higher. The Zalman cooler costs 1/4 the price of the peltier and provides consistant cooling equal to the best the peltier could do.

      Have actually read the articles ? How exactly do phase change and peltier coolers work similarly ?

      The only similarity there is that they both use electric current. Do you think that's enough similarity to say that they work on the same principles ?

      Or perhaps I missed the point that both were invented in the 19th century ?

      The peltier effect is simply heat transfer between two conductors with different electron densities. That's the whole catch, actually: the flow of electrons generates energy. One side gets warmer due to more electrons "bombarding" it, the other gets cooler due to fewer electrons there.
      The rest is basic heat transfer from the CPU to the cooler surface.

      A phase change thermal engine is based on the second principle of thermodynamics, namely that pressure x volume = constant x temperature

      Reduce the pressure or the volume (or both), the temperature drops, and vice-versa. In particular, there's a closed circuit, filled with some gas, that's compressed on top of the CPU, then expanded in a radiator. When compressed the gas cools down, and takes some heat from the CPU, then the gas is expanded into the radiator which whisks away the extra heat.

But those thin un-finned copper plates are completely useless -- you get better RAM cooling with naked chips and then good airflow directed on the sticks.
