Asetek, a leading supplier of liquid cooling for the computer industry, announced today that it has been granted three new patents for its integrated loop liquid cooling technology. The patents may change the market of liquid-cooling solutions significantly as they cover the very basics of sealed LCS.
Back in the days, liquid cooling was a prerogative of extreme enthusiasts as everything - waterblocks, tubes, pumps, reservoirs, etc. - had to be acquired separately, then manually assembled. Those hand-made liquid cooling systems were expensive, hard to use and leaked from time to time. As a result, water cooling was a technology used by extreme performance enthusiasts. But in 2002 little-known companies called Asetek and CoolIT introduced integrated loop sealed liquid-cooling kits that were efficient, ready to be used out-of-the-box and safe. The introduction of such devices not only popularized liquid cooling in general, but also created the market of complete liquid cooling solutions as Asetek and CoolIT were quickly followed by many others. However, only Asetek applied for patents describing the inexpensive liquid-cooling solutions...

I don’t see how you can patent something that has been in common use for 120 years or more... this BS has got to stop.. this is no different than the backstory in Apple V. Samsung ...
Good for them. But really closed loop cooling is only marginally better than top of the line heat sinks with multiple pipes.

Not if you are overclocking. I had systems made from ammo boxes full of water with anti-bacterial agents with a submersible pump inside, a sealed box to screw on top of the chips, and a forced-air cooled heater core out of a Geo Metro (the smallest one I could find) in the 90’s. Back then, you could save several hundred dollars in terms of $ per performance with setups like this overclocked.
This article exaggerates the complexity of us early cooling enthusiasts. I could take a boiling hot multi-processor Pentium 60 array or perhaps some 80386s mated with some Weitek math coprocessors and keep them at near room temperature with a slightly modified 1966 Dodge Dart radiator and water pump. Heck, some even got by with Chevy Vega subsystems!
Everyone has to make everything so COMPLICATED!
i've been using a ThermalTake Bigwater 760is for about 4 yrs to cool my Q9450, which i frequently push to 4x 100%. temps rarely exceed 45C (currently @ 35-39C with no load) according to CoreTemp. a 5-10C swing under max load is very acceptable in my book.
Maybe I should quantify my statement..mass manufactured closed loop coolers are only marginally better. I personally notice 1-2 degrees difference against my push-pull system.
Hey guys, I’m not a techie but when I was in basic infantry training for Vietnam (got myself into flight school & flew Hueys instead), I theorized all kinds of manpack portable A/C systems. I thought the best idea was a helmet head harness evaporator that would cool the scalp & then the cooled capillary blood would cool the rest of the circulatory system. Crazy, yes?
Before that, I had heard of the Hilsch tube system of cooling air through centrifugal whirling & extraction of the cooled air from the center of the vortex.
