Globalwin Jefi Watercooling Kit Reviewed

Posted by CowboyNeal on 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."

    Hasn't open reservoir evaporative been done many times before, also called a bong? Granted it probably hasn't been done exactly this way, people have been bong cooling for years - its just a little forgotten.

      I know the above got modded as funny, but it really does exist - http://www.overclockers.com/articles389/ . Bong cooling hasn't been that popular in recent years however, seeing as people usually want a sexier way to watercool their PC.

    That isn't H2O, it is Flurinert, and it is rather expensive.

  4. Shuttle - for liquid cooling that isn't a joke by Animats · · Score: 2, Informative
    If you want liquid cooling that isn't a joke, get a Shuttle PC. They've been shipping little breadbox sized machines with heat-pipe cooling for years. We use these in places without air conditioning, and they work fine. We've had five units for a year, and none have ever failed.

    No neon, no overclocking, no extra slots you don't need. Just little machines the work.

    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.

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

  7. Skanky Water by Craig+Maloney · · Score: 2, Informative

    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.
