Hyper 612 PWM
RR-H612-20PK-R1; RR-H612-20PK-R3 (LGA 2011 Version)

Disclaimer: Displayed parts and accessories may not be included in the actual product package.

Engineered for performance, sized for more surface area for heat dissipation, and equipped with PWM fans for noise control, the Hyper 612 PWM is a silent storm that will keep processors running cool. With PWM the motherboard BIOS and software tuning applications can precisely control the fan speed on the Hyper 612 PWM to ensure that performance is always balanced with noise levels. A special heat pipe layout has all 6 heat pipes crossing CPU “hot spots” to deliver optimum thermal performance.

1. Optimized with wider fin gaps and resistance reduction cut-offs for low fan speed condition.
2. Unconventional layout of the heatpipe direction: all 6 heat pipes can cross over the “hot zone” on most of the modern CPUs for better cooling efficiency.
3. Quick-snap fan bracket design for easier installation.
4. Wide range PWM fan (600 – 2000 R.P.M.) provides versatile performance for full loading efficiency and for quiet idling.

      "Where the Hyper 612 PWM really shines is its price, its priced at around half of what you can get the Intel water cooling for making it a great option for someone who wants to keep their 2011 socket CPU cool while leaving a little room in the budget for other important components."

      "With a 150W heat load applied by the Intel LGA775/1155/1156 version of FrostyTech's synthetic thermal test platform, the Coolermaster Hyper 612 PWM heatsink once again rises to nearly the top of the reference list. In this case, the Hyper 612 PWM heatsink yields an excellent result of just 15.1C over ambient at stock fan speed, with a moderate 50.7dBA noise. "

      "For new consumers wanting something more out of their system or the ability to shut up those loud 60mm/70mm/80mm fans whizzing about in the computer case, the Hyper 612 PWM is a solution that gets the job done. The 612 also allows for overclocking without costing an arm and a leg, you can find it online now for about $49.99 before tax and shipping which competes with a range of known and unknown brands but bests them with quiet performance and future support. The copper and aluminum design keeps weight down and placement of weight focused close to the motherboard which lessens the worry on the users, the fins off of the heatpipes at the base offer little additional weight but do allow for venting. The 6 pipe design allows for older users to appreciate it but also have future use for it with larger silicon upgrades, for those with newer chips it’s possible to make 100% use of the cooler right out of the gate. It’s a design tailored for the generation arriving right now instead of exclusively to the generations past. Those with APU chips and planning on Sandy Bridge setups should find this design a great pairing for the hardware."

      "It is well built and looks attractive, is efficient and supports PWM rotation speed control, which makes its fan moderately noisy up to 1100 RPM. Moreover, Cooler Master Hyper 612 PWM will ensure processor stability at very high frequencies and core voltage settings."

      "The Cooler Master Hyper 612 PWM looks like a great cooler and, this time, appearances were not deceptive. It is a great cooler indeed, with a terrific performance and a good noise level."

      "We got a really nice idle temperature of 29C, which might be the seller for some, but the load temperatures just weren’t that impressive."

      "At the end of the day we were very happy with the Cooler Master Hyper 612 PWM. The performance was very similar to quite a few other coolers that we've tested over the years but the MSRP of ~$49.99 is what set this cooler apart from them. While the Hyper 612 PWM might not win any style awards, its performance and value make it a very good choice and due to that fact has earned our "Editor's Choice - Gold" award."

      "The Cooler Master H612PWM handled the fully loaded i7 930 @ 4.0GHz well enough to keep it below 90c degrees. Considering that most future platforms will use less power and produce less heat we believe it save to say that this cooler will perform well here. The gathered results are good even without a 2nd fan attached."

      "We have the massive, heat gulping Hyper 612 PWM, and then we have the small, conservative, and thoughtful GeminII S524. Both are easy to install and offer great performance for each application. For the Hyper 612 PWM at a price of $49.99 it is definitely a great alternative to spending upwards of $80 and $90 on similarly performing coolers. The GeminII S524 price has not been listed yet, but at my estimated price of between $40 and $50 it is also a great choice for someone with a small, low-clearance case!"

      "If you are looking for cooling rather than glitz, there is absolutely no CPU cooler in this price range I would recommend over the Hyper 612 PWM......If you want Enthusiast Class cooling at a Mainstream price, the Cooler Master Hyper 612 is the CPU cooler you have been waiting for."

      "The Cooler Master 612 PWM is certainly massive but it's also quite affordable, and proven to be a very capable competitor.   Let's not forget that some premium coolers don't even come with a fan, so when you factor in the great cooling, low noise, and tempting price tag, we're left with a very good heatsink in the Cooler Master Hyper 612 PWM.

      "Our overall experience with Hyper 612 PWM has been nothing more than a pleasant one. So please consider Hyper 612 PWM if you are looking to upgrade or build from scratch a new system. A strong 9 out of 10."

      "When it's all said and done, the Hyper 612 PWM is a performer, and a great value performer at that, earning it some of the "big brother" honors as bigger version of the insanely popular Hyper 212+.  At the $50 price point, it looks already as if this will be yet another hard value to beat, and another winner from Cooler Master!"
