GlobalWin TAK68 HSF Review

The Sink



As stated in the Introduction, the heatsink is made of aluminum. Aluminum Alloy 6063T5 to be exact. While I don't have the metallurgic skill required to tell you exactly what materials make up this alloy, I can say that it is the same aluminum compound that was used to make other high quality heatsinks from GlobalWin and Vantec. With all of the copper units available today, I was a bit surprised to see aluminum still being used for a cooler designed for a high-end setup.


But even though it's not made of the popular (and more expensive) copper, it still manages to give some impressive stats. It measures in at 62mm x 66mm x 75mm and weighs in at just over 400 grams. The weight surprised me a bit, but with this much mass to work with, we may just have a winner after all.


The design is also unusual in that it has a central divider made of aluminum that goes from top to bottom. The purpose of this is to create two completely separate operating areas within the heatsink itself. Each fan will be mounted outside of one of these operating areas and will be responsible for removing the heat from top to bottom of it's own little area. The idea here is to keep the two fans from just blowing at each other and basically cancel out the efforts of its partner. Without the divider, it would just be another case of ineffective cooling (like the early Orb coolers from Thermaltake). This allows for both fans to work together and not work hard for minimal effect.


The Base



The first thing that I noticed when I looked at the base of this cooler was the presence of that dreaded little piece of plastic clinging to it. We all know what that means…



Frag Tape! I can understand the desire for manufacturers to put a thermal interface on their heatsink, but I'll always be one of the first ones to remove the offending substance. So with just a little effort and a sharp blade, we're left with the actual base of the heatsink.



It basically resembles the rest of the sink, but with most of the coloring gone. Since there wasn't a clear difference between the base and the rest of the heatsink, I was concerned that it wouldn't be smooth, but those fears proved to be unfounded. The base was nice and flat, and had no ridges or grooves to be worried about. I've had full copper bases that weren't as smooth as the TAK68.


The Fans



The dual fans on this cooler are very slim models, which manage to keep their slower spinning blades at a tolerable noise level. Normally, the idea of using these thin fans would be immediately frowned upon, but the fact that there are two of them makes you sit back and take a closer look at the whole picture. We talked earlier about how the fans worked together, so lets see what these little things are all about.


The fans measure in at a very slim 60mm x 60mm x 15mm, so small would be an understatement here. But just because they're on the puny side doesn't mean that they're weak in the knees. Each fan spins at a rated 4700RPM and has just over 23-CFM in airflow blowing from its little shell. Since the fans work independently without conflicting with each other, that brings us to a total of over 46-CFM total airflow working in the cooler. Things are beginning to look a little better now.


When I checked the GlobalWin site, they had these fans rated at nearly 37 dBA of sound output, but I don't think that it is a very accurate rating. At that level, they would be getting close to the noise let out of the faster and larger 60mm fans, and this unit doesn't even come close to that level of output. I had to start cutting power to my case fans to be able to even hear this cooler doing its job.


A final note on the fans is the fact that you have both a 4-pin Molex and a 3-pin connection to hook up. The Molex will take care of the power to one of the fans and the 3-pin will handle the juice to the other, and will also allow you to monitor fan speeds through the BIOS or software utility. This way, if you don't have more than one fan header on your motherboard, you won't be left in the dark for the second fan. Kind of nice when a company actually thinks its way through a design and allows for alternatives.


The Clip



I think that one of the reasons that I enjoy testing different products is because it allows you to see ingenuity at its finest. While this is probably one of the strangest clipping mechanisms that I've seen so far, it was surprisingly simple and effective. This clip goes all the way over the heatsink and allows for the use of all three lugs on each side of the Socket. Here's what it looks like after being attached to the unit…



Installation was easier than I would have thought it would be. After applying the thermal interface to the processor and laying it into the Socket, I simply took a long flat-tip screwdriver and pulled out slightly on the back leg of the clip. This allowed me to slip it onto the three lugs on the backside of the Socket. Once it was firmly seated onto the lugs, I just laid the cooler gently onto the processor and used gentle pressure to attach the front portion of the clip to the three lugs on that side of the Socket. After that, you just tighten the screw on the top until it won't turn anymore. When it won't go any further, you have the proper amount of pressure on the clip to maintain a large sink. When I checked the installation, there was no movement at all of the heatsink atop the processor. Here's what it looks like when mounted into the system…
