Introduction
In the past few months a new "trend" in all copper heatsinks has arisen. At first it was the Japanese imported Kanie Hedgehog. Since then, many others have followed in Kanies footsteps. Blizzard, OCZ, CoolerMaster, Zalman, and now GlobalWin. The makers of the beloved FOP38 and others. I will be taking a look at the GlobalWin CAK38 that was provided by Proton Computers.

Accessories
The CAK38 comes with the following

Copper is quite the sexy metal.

I was glad to see all of the accessories that came with the CAK38, except the TIM (Themal Interface Material) which is just plain awful like almost every other TIM that comes preapplied on heatsinks. When I peeled off the plastic protective tab half the TIM came off. I don't know if it was just this unit or what. But the TIM just plain sucks, and I'm sure if I could've used it it would had been pretty bad. Most TIMs that come with HSFs are pretty bad. And I highly suggest using Arctic Silver or Arctic Silver 2 with any HSF. TIMMMMMMMMMMAY!!!!!!

The 3 to 4 pin pass through is included because this certain can type can and will burn out the 3 pin connection on your motherboard if used. And I HIGHLY suggest you connect this fan to a molex using the pass through cable. When I first opened the box the CAK38 came in I was very suprised. It was packed in a custom made foam piece. The CAK38 fit perfectly in it. I commend GlobalWin on this. My FOP 32-1 came in a box with no padding/protection. Improvement is always better.

Unlike many copper HSFs (mainly the Kanie Hedgehog) that are not entirely one piece, the CAK38 is made out of one solid block of copper. Which means better thermal conductivity. The bottom of the CAK38 looks somewhat smooth yet has small dents in it. I have no clue why or how. However none were around where the core would rest so it was A OK by my standards.

The space between the CAKs fins is the same however the fin thickness is VERY different on them. Almost every fin is a different size. Its like a grabbag of copper. This shows a lack in precision machining. Hopefully this doesn't affect the cooling of the CAK38. But I can't tell since all CAKs are like this. The fins are about 5/16" deep, and from what seems to range from a little over 1/64" to 1/16" thick. The fins rise around 1 1/8" high. All I can say about the thickness of the fins is that this is pitiful on GlobalWins behalf. In fact if you pluck at each fin they have a different tone. Possibly make a band. Der NodenFliederMause and the CAK quartet. :-D

The CAK weighs in at a hefty 14 ounces. Its all copper construction is worth it though. And the GlobalWins clip does do the job of securing it to the socket tabs. The Black Label Delta fan is attached using screws, risers, and some fin type of device used to hold the fins together so that the screws can hold and not become loose. Some HSFs have better ways of attaching their fans, but this method is sturdy and it does its job fairly well. Odd thing about the CAK38 is that the fan is set up on risers. I have not seen this before that I can remember. And I have not much of an idea of how this affects cooling but it seems like it should help as the air isn't as forced straight into the fins. These risers are a little more than 1/4" high.
