Extreme water cooling

<< < (3/3)

schmitt trigger:
The Cray 2 Supercomputer utilized Fluorinert liquid cooling back in the mid 1980s

However, because of its harmful atmospheric effects, I ignore whether it is still available.

TimFox:
The CDC 6600 had a pressure gauge on the front panel to monitor the Freon refrigeration system.

Actually, I was thinking about no heat sinks at all. Just water

It would work if you live on Mount Everest where the boiling point of water is about 70°C. But at sea level in normal air pressure nope.

EDIT: Unless you are cooling something like a reasonably power saving laptop CPU or one of those low clocked low power binned Intel desktop chips. Those might produce so little heat that it works. But then again you can cool these CPUs without even using a fan if the heatsink is fairly big.
