Globalwin Jefi Watercooling Kit Reviewed
shockNZ writes "[H]ardOCP has reviewed what appears to be a first in PC watercooling - an 'open reservoir evaporative cooling system.' The Globalwin Jefi has a radically different design to most systems on the market. The reservoir is open at the top, and utilizes something akin to a showerhead in order to rain the incoming hot water from the PC down onto a floating heatsink. Perhaps surprisingly, it demonstrated excellent performance and low noise levels - and as a bonus, the reservoir can be used as an aquarium."
This type of cooling is used in power plants - particularly nuclear. That's what those cooling towers are doing. The coal fired plant in my local town uses towers as well. It's very efficient.
It may be a bit too noisy for the silent enthusiast crowd. With the pump producing 22db and the fan doing 20db at the lowest voltage, it is not as silent as the Zalman Reserator. Then again, if you used the Zalman product on an AMD 64, the reservoir would double as a drip coffee maker.

well yess, actually since ancient times :)
but also in supercomputing.
those cray supercomputer beauties had a big aquarium with something best described as indoor waterfall to cool the water back down
Because it takes dramatically more energy to run a compressor than it does to run a gentle little pump and a couple of fans, probably. Besides, there are $500 products which have an air conditioning system in them, probably running R134A. Or, you could just adapt a window A/C unit or something.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
The tap water here in Tempe, Arizona, is quite hard. If you don't dry the dishes, you'll get lots of spots on them. (Never bothers me, but some....)
Combine that with the very low humidity here and this kind of evaporative system and it wouldn't be long before, instead of tubing, you had solid bars of mineral salts covered in rubber.
Of course, you could buy de-ionized water, but, for me at least, that'd get old pretty quick.

All but God can prove this sentence true.
It even came with it's own glass waterfall thingy to keep the board happy.
To a silent pc purist, water pumps are BAD. I am more interested in a geo-thermal (ground-based) system, or truly passive, convective water cooling, or maybe some kind of passive water cooling that plugs directly into cold water pipes so that it works as a kind of pre-heater so that the water heater in the house doesn't need to do as much work.
This is a cool idea though, if you can manage do find or build a quiet enough pump.
Quite an experience to live in fear, isn't it? That's what it is to be a slave.
