The Contenders and Installation

This content was originally featured on Amdmb.com and has been converted to PC Perspective's website. Some color changes and flaws may appear.

The three heatsinks will be introduced in the order they hit the marketplace, please remember that we are using the same 60mm Delta 37cfm fan on all three units for optimal performance, if noise is an issue for you, then you might want to consider a fan that produces lower cfm’s, but remember it will affect your performance downward.


The Kanie Hedgehog pictured on the right is the granddaddy of all copper HSF’s (at least the first affordable one) by computing standards. It led the pack as the best pre-GHz high performance HSF. I have fond memories of this beauty, for it started my quest for Cooling Excellence. Loved my Hog!!!


In its day it was the heaviest heatsink out there weighing in at 500 grams (with fan). The construction is comprised of copper pins that are press fitted to the copper base. This HSF was designed to be used with its shroud in place (as pictured) and with the fan sucking air up through the pins and out into the case. Many people believe that the Hog is a better performer with the shroud removed and the fan blowing down on the pins, for me it works better as designed.


Installation is quite simple (as long as you didn’t drop it). The clipping mechanism, very similar to that used on the Alpha heatsinks hooked on to the middle flange, on both sides of the socket. I always used a needle noised pliers to install the front clip, I couldn’t do it with fingers alone. The clip always worried me thought, I could grasp the HSF and it would actually lift up from the CPU’s core, but it has never caused me a problem, that is, until I tested it with Fan adapters, then it did lift up and had to be stabilized. The Kanie Hedgehog was provided by Tony of Plycon.


The OCZ Gladiator pictured on the left has the lowest profile of any of our contenders standing at 2.125 inches or 52 mm high and is also the lightest in weighing 380 grams (the height and weight include the fan). The Gladiator incorporates “thin fin technology” which aids in maximizing the surface area for greater heat dispersal. It is covered on three sides by a retaining shroud and the fan screws do penetrate through to the fins bending the end fins slightly. The Gladiator substantiates just how effective “thin fin technology” is. The Gladiator is designed with the fan blowing down on the heatsink.


Installation is again, quite simple, you hook the rear clip to the center flange of the socket then hook the front clip on the center flange on the front/top of the socket. Your Gladiator is installed and no tools were necessary. This has to be one of the best single prong clips I’ve ever used and it is strong. Oh, don’t get me wrong, it still took pressure to install, but with their great thumb clip, it was quite easy. The Gladiator tested very well with Fan adapters (see our review of Fan Adapters) The OCZ Gladiator was provided by http://ocz.safeshopper.com.


The GlobalWin CAK-38 pictured on the right is the latest in the long line of quality HSF’s produced by this trusted company. At one time or another just about every performance loving computer user has had a GlobalWin HSF on his/her machine. The CAK-38 weighs in at a hefty 510 grams making it the heaviest of our three contenders. It is also the tallest at 2.625 inches tall or 65 mm (weight and height includes the fan). The design of the CAK-38 is quite interesting in that it features six rows of flat fins for a total of 138. Please notice that the fan actually sits on four grommets (I say grommets only for a lack of a better word) that raise the fan 6 mm above the heatsink. What this effectively does is cool the outside area of the fins as well as the center. This HSF is designed so that the fan blows down on the heatsink.


Installation was (to put in mildly)!*^%$ *(&!. Even with a newer clip design it still is one of the hardest clips to install and you can’t do it without using a screwdriver or needle nose pliers, even then the pressure required was considerable. The back clip connects to the middle flange of the socket while the sweat starts to flow when you attach the front clip to the middle flange at the top of the socket. Once installed it does a good job of cooling your CPU. The GlobalWin CAK-38 was supplied by Christi and Chris at NerdsByte.
