As I said last time, cooling is very quickly being recognized as an important part of computer technology and innovation. As such, I've got a stack of heatsink fans sitting on my desk like a lineup of soldiers trying to get into the Navy SEALS or Army Rangers... waiting for me to weed out the maggots from the elite.

One of the more well known companies in cooling today is Globalwin, and they are nothing short of a success story in themselves. Three guys started the company back in '92 doing all the marketing, production and delivery themselves. They are a 10 million dollar a year company today.

Personally, I usually associate Globalwin with great performance at the price of silence. One of the first coolers that I remember the name of is the Globalwin WBK38. While it's not up to the standards of their current products, that HSF was a very nice performer but for a year or so, it would keep my room filled with a loud hum.

The CAK4-86 is leaps and bounds over the technology used back then, using copper instead of aluminum, and a 80mm high speed screamer rather than a 60mm. Some other newfangled techniques such as the skiving process for the heatsink fins and a off-set airflow made possible by Globalwin's "Blue Tai-Chi". Do any of these things actually matter? Read on.


Heavy. This thing is HEAVY. VERY heavy. It's like I snapped Linda Tripp onto my motherboard. This massive HSF weighs in at just over 800g, more than double what the Vantec CCK-6040H and the Thermaltake Volcano 9.

However, the heft is testament to the great quality of this combo. The copper at the base is very thick and has no less than 40 fins. The base can be removed by undoing a few screws. Why? The CAK4-86 can be used on both Socket A and Socket 478 platforms.

The fins themselves, produced by the skiving process, are extremely thin. I first saw this heatsink production method in Cooljag/Dynatron's JAC102A. Basically, the idea is to make the unit from one solid block of metal without welding or other methods of attaching the the fins to the block. The fins are finely shaved from the block of copper and as a result, you get very thin heatsink fins, increasing the available surface area for heat dissipation.

The finish on the bottom of the aforementioned heatsink is also very nice. You can't use it as a mirror and it's not quite as smooth as the Vantec Copper-X but you can still probably skate on it... if you were some kind of magical hockey gnome that can skate on copper... Anyway, most people will just go with some good thermal compound but you can try to sand it down further if that's your thing.

Globalwin, like everyone else, includes the usual thermal compound. Although it's not a big deal to me, at least Vantec had the courtesy to send something relatively decent in a little mini-syringe. Everyone else includes this white junk in the little plastic bag. This is a heatsink, not instant noodles.
