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."
What happens when this thing fails? Bye bye computer? I fail to see why people are so interested in liquid cooling or is it just the overclockers who use open loop liquid cooling like this?
The only novel idea in this whole thing is the open tank shower cooler - which also poses the spill hazard. Admittedly the tank looks like a futuristic acrylic ventilated crab and could be considered cool in some sub-cultures - BUT - if you have kids (yeah, some ./ers do!) or pets KEEP THIS system away from your PC. If you think you have problems with your dog drinking outta the toilet bowl now....
See that long UID - that's what you get for lurking too long
with open circuit watercooling system is water contamination. Algae seems to be able to grow on little more then the casual dust that enters the water, and the best place to grow is where you dont want it: The nice warm and thin parts of the CPU heatsink.
HI O WISE PRINCE. WHT TOOK U SO DAM LONG?
Why did they not use pressure water like system?
It would have been able to handle the heat of overclocking and woudl not need much changes..
they system they had is what predated the pressued coolant/water radaiators incars..
instead of using un environment friendly glycol you could use a freon subsititue..
Don't Tread on OpenSource
.. for "cases and cooling". God knows I'm sick to death of seeing Yet Another Case Mod and Yet Another Cooling System.
I've finally had it: until slashdot gets article moderation, I am not coming back.
I don't think this guy has ever really owned an aquarium. There's no way you could have it do double-duty like that, and I can sum up the problem in one word: algae.
For your security, this post has been encrypted with ROT-13, twice.
Is it just me, or does anyone else out there think that an open container of water on your PC is a bad idea? I generally work with a cup of coffee or glass of Coke next to the keyboard, but that's a little different than having a fishbowl's worth of water sitting on top of my PC. Of course, I have really clumsy friends too...
I planned on inserting something witty here but never got around to it.

Its been done before.
Fish Tank Water Cooler
It's nice that this comes in a kit but it's usually cheaper to build it yourself. 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.
The problem with that approach is that oil isn't nearly as efficient at wicking away heat from the processor, nor able to cool down as easily as water. It's a fantastic lubricant, which is why it is in your car's engine, but notice it doesn't live in the radiator for precisely these reasons.
