The Heatsink



Though nothing is really out of the ordinary here, the size of this heatsink makes you take notice. With measurements of 80mm x 63mm x 35mm, it does tend to be a bit larger than average. But even with the larger than normal size, I had no problems fitting it onto the EPoX 8KHA+ motherboard for testing. Considering that this is one of the tighter fitting boards on the market, it shows that it is still usable by nearly every motherboard made.


The material used for the sink is aluminum, so I wasn't really expecting a whole lot from the very start. While this material is all right for some of the older processors, it has shown it's age when it comes to cooling a heated Athlon XP processor. But again, we'll run it through our battery of tests to see how it handles the heat.


Before we get to that, though, it should be noted that the larger size helps it in two main areas as far as cooling is concerned. Surface area and mass. The larger size creates a good deal more surface area for the cooling process. And while 250 or so grams isn't a huge amount, it is heavier than a good many aluminum sinks on the market today.


The Base



As you can see from the picture above, the base of the sink shows the machining marks from the manufacturing process. While there weren't any ridges to be felt with my fingers, a good lapping would still be highly recommended.


The Fan



I always enjoy looking under the hood to see what powers the new breeds of heatsinks today. A lot of manufacturers have opted to use the might Delta fans, but while effective, they tend to be unbearably loud. So it was a nice surprise when I checked out the underside and found a Y.S. Tech fan sitting on top of the sink.


This particular fan measures in at a standard 60mm x 60mm x 25mm and spins at roughly 5500 RPM. This slightly slower fan speed keeps the decibel rating at less than 40 dBA while still putting out 31-CFM of airflow. Not too shabby for a fan that won't keep you up at night.


But while the fan is promising, there were two concerns about it. First was the lack of a fan grill. Too many of the current crop of motherboard has a main power connection that forces the primary cabling to be close to the processor socket. This is just an accident waiting to happen. Secondly, there was no 4-pin Molex converter. Though the draw isn't as high as many other fans available, it is still a good idea to run it from the PSU and not a mainboard header.


The Clip



When I first saw the clip, I was glad to see a design that used all of the socket lugs for mounting. But when I actually installed the cooler, I nearly fell in love. Though of simple design, the swivel head of the front clip goes on very easily. This is one of the least forceful clipping mechanisms that I have used so far. But even with the ease of installation, there was no side-to-side movement of the sink when it was mounted on top of the processor. Very nice job here!
