It's the most efficient GPU cooler you will find, and in 2 particular independant tests, performed better than off-the-shelf liquid cooling (Accelero Hybrid).
As long as you have the physical space for this card (3 card slots without fans, 4 with, plus 2" of clearance on top the card), this is truly a must have--for the enthusiast, the extreme overclocker (myself), or even the casual gamer.
By design, it supports passive cooling for almost every GPU it can mount to, but it really shines when you add 2 140mm fans. The fact it's universal (fitting almost every current and future single-die graphics card) makes it even more valuable. My suggestion is to couple this card with two 140mm fans (I suggest the Prolimatech Blue Vortex 14, as it's the quietest of all 140mm fans I could find, while still providing the same airflow).
So far I've installed 12 of these, and I have many more to install. I'm ordering these units by the crate where possible, and as they're available (from Amazon and other websites). They're really awesome!
For those curious, installation time took me about an hour for the first card (went slow to figure out how best to do many of them), but the next 11 took about 2 hours, give or take. I did each step all at once which helped. Shouldn't take more than an hour for just one card for the average user.
* Nearly universal - fits a wide assortment of GPUs, and will fit many in the future
* It's a simple "bolt-on" solution - if you've changed GPU coolers in the past, it's not really any different
* Superior cooling/thermal capacity - blows away the competition
* Passive & Active design - You can use it with/without fans. Using the suggested fans, it's nearly silent
* Includes everything you need, with plenty of thermal paste (I was able to use 1 tube for 3 GPUs)
* This cooler is amazing because of its physical size - the card sticks about 2" above the card. Without fans it sticks about 2.5" beyond the side of the card, and another inch with fans. You will need a unique case, or open case or open air design to hold the cooler.
* The instructions included aren't as detailed as they could be - the website includes very high quality/very detailed photos of general installation. Use the website and the included instructions together. For someone who has done this before, you probably will only need the paper instructions to tell you which GPU die adapter to use, the rest is self explanetory.
* Some folks noted installation difficulties, even multiple hours per change -- anyone experienced with cooler swapping shouldn't have many issues, but it will depend on the card design. I saved time (probably more than half an hour) by NOT removing the stock thermal plate from my GPU's, instead I added extra heatsinks on top of it. Remember, the more metal there is to soak up the heat, the better--just make sure you add heatsinks and the fan can blow on them to dissipate the heat.
* With the fans, most of the hot air will be blown past the card (ie, away from the back of the card) instead of toward the rear or front of the card. So keep this in mind with your design.
I run a small GPU farm and wanted to ensure longevity with my MSI 7950's by keeping temps low, and make it easier to cool them during summer. As a bonus, I wanted to lower the fan noise level as well. I spent a month researching and talking to people, narrowing my results to the Prolimatech MK 26 and the Accelero Hybrid. I had also considered making my own closed-loop cooler (like the Accelero Hybrid), but I wanted more of a bolt-on solution than having to take time to get the water block mounted to the GPU. Especially considering I'm doing racks of these conversions, and not just one or two cards.
In the end, what sold me on the Prolimatech over the Accelero was it's future-usability (being nearly universal), and the fact there were fewer parts to fail. If the fans on the Prolimatech failed, the GPU would still be cooled (just not as well). If the Accelero pump failed, my GPU was dead. Also, as mentioned above, in several tests the Prolimatech and Accelero Hybrid were a dead-even match in noise level and cooling capability--in 2 particular tests the Prolimatech was quieter by 2 decibals.
* Multiple Racks of MSI TwinFrozr III 7950 GPU's, slightly overclocked. Each rack has 12 GPU's. Each GPU is scrypt-mining over 700kh/each. Each rack = 8,400mh/s
* Running the TwinFrozr coolers at max RPM would keep the cards between 78-85*C with ambient air of 20-28*C
* Noise level of each rack (12 cards) was equivalent to a 20" box fan running on high
MY RESULTS - With the Prolimatech MK 26 & two 140mm Prolimatech Vortex 14 fans @ 1,000rpm:
* With ambient air of 20-28*C, the cards average in the mid 50*C range, with some in the mid to low 40's, and some in the low 60's. This variance is due to where the GPU is in the rack (near the floor, or near the ceiling)
* I did a summer "burn" test by shutting off the air cooling system and letting the GPU's heat the room up. With ambient temperatures over 45*C, the GPU's remained between 55-65*C. Amazing!
* Noise level for each rack is literally a whisper. I have to stand next to the rack and put my ear toward a fan just to hear it running. I would say, it's no louder than a desktop PSU fan. Astounding.
The results were fantastic and my idle temperature dropped 6 degF. I usually watch a lot of Blu-Ray quality video on my machine and my card temps used to be 110 degF. when playing. Now they are 91 degF. To sum it up I’m very pleased with the purchase of this kit. Just be aware that this heat sink is large. It worked fine in my Corsair 500R case.
