Summary: The Coolermaster Hyper 612 PWM heatsink stands 163mm tall and weighs a pretty hefty 806 grams. The cooler is compatible with Intel socket 775/1155/1156 and LGA1366 processors, but crucially not LGA2011 Sandy Bridge-E CPUs. AMD socket AM2/AM3/FM1 processors are supported.
The Cooler Master Hyper 612 PWM is a very large CPU cooler. Adding a second fan, while decreasing your temperatures, will make the cooler much larger and may even cause some clearance issues.
Summary: When I first received the Hyper 612 PWM in the mail I was very interested to see how it was going to compare to the last Cooler Master cooler (The V6 GT) I had reviewed (which had done very well in our testing).
Pros: Good Performance, Compatible with lots of different CPUs, Ability to add an additional 120mm fan
Summary: Performance of the Cooler Master Hyper 612 PWM was outstanding all around. Temperatures were best in class even under heavy load. PWM kept fan noise to a minimum and installation was simple, secure and very easy.
Excerpt: Our friends at Cooler Master are at it again with a few new coolers coming to market this year. The first is the Hyper 612 PWM. Following the success of the Hyper 212 Plus, Cooler Master has decided to add another cooler to the Hyper lines.
Conclusion: Please remember that these test results reflect our experience with each cooler on a specific motherboard, with a specific processor, BIOS revision, BCLK and voltage settings, and test programs. The results of this test cannot be directly compared to other tests since many factors will have changed.
Pros: Amazing performance for the price...for any price, really, Almost silent operation, Quiet, PWM-controlled fan, Extra fan mount included
Cons: Protective sticker leaves residue on heat sink base, Rather pedestrian appearance
