VapoChill Puts a Pentium 4 with 800 MHz FSB within Reach

The VapoChill Premium Edition Cooling System

We at Tom's Hardware Guide gave you the lowdown on the VapoChill system in December of 2000 , so in this article we'll be focusing on the changes made to the original system.

The technology behind it is still the same:

  • A compressor (Danfoss R134a) is used to generate overpressure of the coolant.
  • The coolant is fed through a line to an evaporator, called a copper head, which has to lie directly on the processor.
  • The coolant absorbs the heat dissipated by the processor and evaporates. While in this gaseous state, it is pumped back through a parallel line to the compressor, where it is compressed again, thus completing the cycle.
  • The compression generates heat, which is dissipated through ventilated cooling ribs. The entire set-up requires up to 72 W and can remove up to 160 W from the CPU.
