Back when to me, there was an advantage to 
overclock my computer as much as possible 
while not throwing errors, I used water 
cooling using what was called a "Cascade" 
impingement block from it's maker in 
Australia. Still have it...  

As I was recording music with the computer 
and it being in the same room as the 
recording, I needed it to be dead quiet as 
much as possible. After some consideration 
I realized I didn't need a fan at all and 
instead ran an Iwaki aquarium pump (in a 
sound insulated container) in the far 
corner of the room, connected to the water 
cooled hear sinks on the computer with 
cheap Tygon tubing bought on ebay. The 
fluid was an antifreeze/water mix which 
also prevented algae formation.

The heat from the processor and 
northbridge/southbridge chips was lost 
from the Tygon from and back to the 
computer and the processor's core 
temperature was always kept low and no fan 
was ever used in the system. It was 
flawless and lasted the 5 years I used the 

My idea of water cooling to get rid of the 
fan noise. It worked brilliantly if I do 
say so myself.
