Thermaltake Volcano 4005 Heat Exchanger
 

This Volcano 4005 Heat Exchanger from Thermaltake is one of the best CPU
cooling, the cooler itself combines the air and water cooling together and
give an excellent cooling performance to the CPU. It was also totally
fanless CPU cooling solution unless an optional fan had been installed to
it. By using this cooler, you might also need a good pump in order to make
sure the water flow is able to get through all the loops in the cooler.
The Volcano 4005 Heat Exchanger is also support the Intel P4 ( Socket 478
), P4 LGA 775, AMD K8 and K7 platforms of CPU cooling. The only bad thing
from this cooler is the weight which is consider a heavy weight CPU
cooler. But, it might not be a big problem as long as having a proper
installation of it.
