Prolimatech MK-26 GPU Cooler Review

Prolimatech is hoping to continue this status as they move forward. Their reign as one of the top CPU cooler makers has been interrupted with the introduction to their second GPU cooler. The MK-26 is a large cooler that is designed to accommodate two 120mm or 140mm cooling fans as well as dominate the heat built-up by some of the world’s faster video cards.

Prolimatech MK-26 GPU Cooler Review

 

Introduction

There are companies out there that I would classify as being perfectionist. A company whether small or large that tends to put a lot into the products they bring to market. And no, you cannot say that about all companies. I will not list all the companies I think fall into this category but I will name one. Prolimatech. From the first time I saw an image of their Megahalems CPU cooler I knew they would make a name for themselves in this industry. It performed at the top of its class and has not looked back yet.

Prolimatech is hoping to continue this status as they move forward. Their reign as one of the top CPU cooler makers has been interrupted with the introduction to their second GPU cooler. The MK-26 is a large cooler that is designed to accommodate two 120mm or 140mm cooling fans as well as dominate the heat built-up by some of the world’s faster video cards.

Prolimatech’s take on the MK-26

The MK-26 is a top of the line VGA cooler.  Engineered to provide 320 watts TDP of baseline heat dissipation, it is the highest performing VGA heatsink in its class.

The MK-26 has been designed and built with a high regard for quality, guaranteeing excellent performance and long life.  It is constructed with dual aluminum radiators that are fed by six nickel plated copper pipes.  The dual radiators allow for the installation of two 140mm or two 120mm fans.  The dual radiators, when combined with two fans, will not only cool the VGA processor, but also increase air flow across the entire VGA card and improve system wide cooling.

The MK-26 comes with an array of state of the art design features that include the Omni-mount universal tool-free mounting system.  Omni-mount allows for quick and easy installation while also providing wide compatibility with new and future VGA cards (see compatibility list).  The MK-26 also includes the excellent performance PK-3 thermal compound and a special Y-split connector that allows two fans to be powered by the VGA board.

Closer look

The cooler is designed to dissipate heat up to 320 watts TDP. At this point this would include all the current video cards as well as past ones. The reason for it to be able to handle such a large volume of TDP is because of its overall size which includes a lot of fins, six heat pipes and evaporation cooling system.

Like we stated earlier the cooler is large, very large. Once mounted to most NVidia or AMD graphic cards, both can take up as much as five PCI slots on the motherboard. The cooler along measures 10.12″ long, 5.74″ wide and 1.85″ tall and weighs in at 1.28 pounds.

The MK-26 is a two fin array style cooler but nothing like the dual tower CPU coolers we see a lot of. The two fin group branch off into two different directions spanning over the entire GPU once installed. The .5mm thick fins are not very dense which would allow slow spinning fans to be a great opinion to pair with it.

The top of the fins are made in such a way that either a 120mm or 140mm fans will sit comfortably. And the indentations you see along the outer edge of the fins are where the mounting brackets for the fans will sit.

From this angle you get a good look at the heat pipes that starts at the end of the cooler and runs through the base of the cooler. The MK-26 uses 6mm diameter pipes which is made of copper but layered in nickel.

The base of comes with a protective strip to protect the polished finish.

The cooler comes with quite a bit of extras that will need to be applied to the cooler itself or to the GPU. In the first image we have all the mounting hardware. And like we stated before it comes be mounted to most NVidia and AMD cards with the exception of just a couple.

Mounting images

When it comes to installation manual of component it tends to only show images and not much wording as most of the times the images are enough to show the general process in which to install it. With the MK-26 I have to point out a few things that will make life a little easier with it.

To begin with the instructions are step-by-step with each and every model of video cards. Unless you are mounting it to a Radeon HD 79xx card, you may have to do a little guessing like we did with our Radeon HD 5870. None of the decision making is mind-blowing just know you will have to make some. An example is which heat sinks to use and where.

The installations of the heat sinks do require to you really clean the resistors or VFM that you are placing them on. This is one step you don’t want to neglect. Even after all the cleaning, I did not seem to comfort with how the heat sinks adhered to the components. After pressing them on with a decent amount of force and letting them sit for a minute it did adhere to the components rather and was more than comfort enough to place the card on the test bench afterwards.

For the testing Prolimatech did provide us with a couple of their new Ultra Sleek Vortex 14cm cooling fans. This blowers are pretty thin at 15mm. This doesn’t add much to the the height of the cooler after it has been mounted. Before or after the cooler will still have a triple slot configuration.

In order to install these fans on this cooler you will need the require hardware also provided by Prolimatech. This would be the MK-26 Series USV 14 fan clips. I was surprised to see that Prolimatech offers all kinds of clips to mount any of their fans on any of their coolers.

Finished product.

Testing Begins

Results

Conclusion

The Prolimatech MK-26 is a pretty large cooler and if you have never dealt with 3-slot GPU before, you after installing this cooler. But giving up space is sometimes the price you have to pay in order to get better cooling performance out of a GPU.

Using the MK-26, we were able to drop the load temp of our test Radeon HD 5870 from 60 plus degree to an amazing 40 plus degree. Gaining a 20 degree cooling GPU can one ….. extending the life of your video cards and two in the case of the MK-26 also drop the overall noise of your system. We used the Prolimatech Ultra Sleek Vortex 14 fans in our testing and we heard nothing from them.

The installation of the MK-26 is not complicated but a little time consuming. If you have been around computers and know what you are doing when building, you may be comfortable with not reading the instructions of most cooling products. Whatever you knowledge skill is we do recommend reading the instruction sheet for this cooler.

The pricing of the Prolimatech MK-26 is currently at $85.
