I had a play with this a few years back

I actually used a scirocco rear washer bottle and pump (how's that for
keeping it on topic?) run off 5v instead of 12 so it wouldn't wear out
or generate as much pressure. I built an aluminium case to go over a
socket 7 heat-sink, but this leaked so I wasn't going to put it anywhere
near my CPU. If I was to do it again I would cut some of the fins off a
heat-sink and wind copper brake hose around it, this would be water
tight at least, if not as effective. I didn't build a radiator, I just
used a reservoir of cold water, but you could easily build a small rad
from brake hose and a fan also.

The heat sink did get very cold, but I couldn't get it too seal 100%
even with loads of silicone. Now the rear end of my rocco is again
more-or-less the shape Karmann made it the washer bottle is back in the
boot and the project went on ice.
