asetek WaterChill CPU Cooler Review
Water Cooling for Pentium 4, Athlon XP, and Athlon 64

When you hear one of your friends talk about a skydiving adventure, or even a bungee jump for that matter, do you tend to smile, nod, and think to yourself, "one of these days, buddy..."?  There is an element of danger inherent to every so-called extreme sport.  However, extreme, by its very nature, implies the sort of excitement you just can't experience mowing the lawn on a Saturday morning.  "Humans simply aren't meant to fly down mountains at 70 miles an hour on a skateboard, as they do in the Street Luge," you argue.  That doesn't stop a fearless few from risking everything for a few moments of breathless adrenaline, though.  Well, the same argument applies to the most daring overclockers, who use unconventional means of combating heat in the name of procuring additional performance. 

Five years ago, I wouldn't have set a Coke can on top of our case, for fear of spillage.  Liquid, in our opinion, had no business anywhere near an expensive amalgamation of components that relied on electricity to operate..  A short time after, a Peltier cooler found its way onto my 400MHz Pentium II.  It was a short-lived relationship, unfortunately. Condensation took the lives of the processor and motherboard a couple of days later, affirming my stance on liquid and electronics.  Yet, the plight of the overclocking enthusiast is a dire one.  I've persisted for the past few years by pushing my equipment to its limit with nothing more than fancy heatsinks and powerful fans. 

And now, I find myself armed with asetek's freshman venture into water cooling, the WaterChill CPU cooler.  Designed with quick-disconnect fittings and a detailed manual, it is apparent the asetek wants to attract cautious enthusiast.  Yet the components that comprise the WaterChill kit are well-built, so that even discerning power users should take heed.  asetek certainly is well known for their hugely successful Vapochill line of high quality vapor phase refrigerated PC solutions.  Let's see if the WaterChill is cut from the same cloth.

The operating premise behind the asetek WaterChill kit is fairly simple.  Instead of employing a traditional heat-sink and fan combinations, which rely on air to effectively dissipate heat energy, asetek uses water as its cooling medium.  The negative implication is, of course, that water and electricity don't symbiotically coexist in a computer.  Implemented properly, however, water is immensely more efficient than air and has a greater heat transfer capacity to boot. 

Of course, water is only effective if it is, in turn, being cooled itself.  While air is continually circulating and is generally in no danger of saturating with heat (unless you live in Bakersfield, CA where ambient air often hovers around 110 degrees Fahrenheit), the water in a water cooling system is less abundant.  Once heat is transferred from the processor to the water block's copper base, then from the base to the water flowing through the block, it is circulated through a radiator, which functions much like that which is found in a automobile.  Air is blown through the radiator (in this case by a 120mm Sunon fan) to cool the circulating water and is once again pumped back through the CPU block, to transfer additional heat from the cold plate and processor.
