Globalwin Jefi Watercooling Kit Reviewed 135

Posted by CowboyNeal from the staying-cool dept.
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."

    • Does the temperature of the water go high enuff to poach them??!

      Nope, but it's still probably not suitable for an aquarium. The manufacturer's test results report water temps up to 29.8 degrees celsius, or about 85 degrees fahrenheit, which is about 8-10 degrees too warm for most common freshwater tropical fish. Even their lowest reported temp is 77 degrees, which is at the top end of what you should consider safe for an aquarium.

I didn't see the price of the kit in the article but I bet you could do a lot better than that cheesy looking fish tank for less money. I guess the radiator thingy sets this apart from the project that I linked to but I don't understand how agitating the water helps disperse heat. It seems like you would be better off with more coolant and a powerful pump.

      agitating the water will cause ripples. ripples increase surface area, just like the "ripples" on a heatsink, allowing more heat to transfer.

    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.
  • This would go perfectly with the Aquarium case mod [nobispro.com] reported here on slashdot a while ago. Then it's all in one box!
  • For anyone who may have a water bed (me included) i have considered using it as a cooler. My initial thought was to do something similar to what is done in this water cooler except closed and relying on the surface area of the bed to put off the heat (also will keep bed alightly warm in winter... no more need for a heater) the only problem i could think of is if someone jumpped on and the presure popped something in my computer (that would suck)

    recently someone suggested running tubes under the bed(touchi

    Ummm... unless you're changing the water in this thing constantly, that water is going to get really skanky really quickly. Plus, if you put ordinary tap water in there, it'll have deposits and whatnot that you probably don't want to be piping around your computer. Ugh! And heven help you if you put that reservoir near sunlight.
  • as a bonus, the reservoir can be used as an aquarium.

    Just what I needed, fish shit circulating over my Athlon. No thanks.

  • an 'open reservoir evaporative cooling system.'

    I saw no mention of how mcuh water evaporates from this thing in a day, but my gut feel says it's gonna be a bunch (>1gal/day). Anyone know any exact evaporation figures?
