Prolimatech burst onto the scene a few years ago with great success thanks to the superb performance of the Megahalems. It became a top-tier CPU heatsink brand almost overnight. Still, the landscape wouldn't look much different if Prolimatech disappeared, thanks to strong competition from the likes of Noctua and Thermalright. The market is so mature and saturated, it's not difficult to find an excellent CPU cooler no matter where you live.

GPU cooling, on the other hand, is more challenging. High-end graphics cores power requirements have long surpassed that of desktop CPUs. The TDP of the most power hungry CPUs has hovered around 130W for many years, while the top GPU requirement has actually exceeded 250W (for example, the Radeon HD 7980), and we're only talking about single core cards. At the same time, discrete graphics cards remain in more thermally disadvantaged positions on the motherboard and inside most cases, with much less room for huge heatsinks. Installing a third party video card heatsink is often a more difficult and delicate operation. Casual PC enthusiasts are less keen on potentially voiding their warranty on an expensive graphics card, so aftermarket VGA heatsink demand isn't as great. Take all this into consideration, and it's easy to see why there aren't that many high-end VGA cooler options available.

Enter the MK-26, a sprawling nickel-plated GPU heatsink from Prolimatech with six heatpipes. The heatsink ships bare, taking either one or two standard sized 120/140 mm case fans. According to Prolimatech, it can handle cards with up to a 320 Watt TDP which is more than any current generation single GPU model. According to the compatibility list, the MK-26 is essentially a universal cooler, supporting almost every mid-to-high end video card that NVIDIA and AMD has released going back four years or so. Of the current generation, the only notable omissions are the GeForce GTX 660 and 660 Ti.

Package contents.

Despite supporting so many cards, there's surprisingly little mounting hardware in the package. Included are just two different sets of mounting clips and bolts, eight ramsinks, and a motley crew of heatsinks for the VRMs and miscellaneous chips that may require additional cooling. The only unexpected amenity is a dual fan adapter that allows users to power and control standard 4-pin PWM case fans using the small 4-pin header found on most graphics cards.
