Review: Cooler Master Hyper 612 PWM CPU Cooler

Cooler Master has been in the game for ages, my first cooler for my AMD XP 1800+ was by CM, a 60mm fan spinning at an RPM so high it was crazy. They’ve come a long way though, today we have a 120mm powered Hyper 612 PWM by the company, packing low-speed fan power with efficient blade design to hurl large volumes of air across the 6 copper heat-pipe design. We’re pitting this against OEM solutions for those of you coming off Black Edition chips or even standard CPU’s, hopefully it gives you guys a taste of what there is out in the world of performance components.

Test system:

  • AMD Phenom 9750 B3
  • Jetway 790GX HA08 ComboL
  • Sapphire HD 4850 512
  • Crucial DDR2 800 (5-5-5-12)
  • Hitachi 1TB 7200RPM
  • Seagate 300GB 7200RPM
  • Cooler Master Real Power Pro 650W
  • NZXT Phantom Case (extra 200mm on top)

Coolers:

  • AMD OEM Cooler – Standard Phenom
  • AMD Black Edition Cooler (2 Heat-pipe design)
  • Cooler Master Hyper 612 PWM

Thermal Paste:

  • Cooler Master bundled paste

Software is another area that would be nice obviously, I used these for the benchmark though and for overclocking.

  • Core Temp 1.0
  • AMD OverDrive 3.1.0
  • HyperPI 0.99b (12M calculation for stress testing)

With all the details out-of-the-way let’s get rolling!

Bundle

The Hyper 612 PWM is massive, you get the box and realize its not your average cooler and it might take a bit of work to get started on installing it. Packaged are fasteners for AMD platforms and all the Intel platforms minus the newly released 2011 socket although there’s no doubt there will be a refresh for it soon.

Going past that and opening the box we get a massive cooler, the 612 PWM dwarfs the Phenom Black Edition cooler in every way, it’s wider, it’s taller, the fan is gigantic and it has triple the pipes of the Black Edition. It’s also surprisingly light minus the base which keeps concern about it ripping the board apart to a minimum thanks to a low center of gravity just over the chip and the anchors connect directly off that base. Many new builders fear that something this big will just rip the socket off the board, thanks to the aluminum fins this becomes a non-issue.

Design

The 612 packs a unique setup, 6 heat-pipes run down the fins to the base, instead of just having a copper base that connects to the pipes, the base is essentially the pipes as they maintain a tight field together to pick up heat. Using copper in this zone allows for superb conduction while making sure not to go overboard, the aluminum fins (all 42 of them) pick up the heat from the pipes and help pull it away, the 120mm fan finishes the job by pushing it out so the cycle continues. It’s a solid design that has proven itself, the U design of the pipes allows for extra distribution through the fins as opposed to a single J style that pulls heat from the base and runs a single row through an upper row of fins. The Black Edition AMD heatsink relies on direct fins across the base of the heatsink with two pipes running overtime to push the heat out of the system, the stock cooler offers nothing of the sort with a machined aluminum body and a fan plopped on top. If we’re going in order of technical efficiency the 612 leaves both of them for dead.

Installation
If you don’t have a newer enthusiast level case you might be positioned to remove the motherboard for installation, even the NZXT Phantom doesn’t have as big of an opening as you would need to install this in the case. With that said, I’ll walk through how I installed the Hyper 612 PWM into the case.

Removing the expansion cards (video, sound, network) and essential  cables I took the HA08 out of the case, I used a standard philips head screwdriver to remove the 4 screws holding the plastic tension frame to the board and back plate. After this I cleaned the top of the CPU surface using rubbing alcohol to strip off the old paste, after that I let it evaporate and applied the new coating. Installing the Hyper 612 PWM requires filling those holes with the 4 rubber spacers included, allowing for just enough cushion for the 4 posts to pass through. With the spacer set, I lowered the motherboard down on the cooler, doing this allowed me to better manage the 4 nuts that needed tightening with equal force across the chip and keep control of the new back plate. The screwdriver adapter made tightening nuts down easy and allowed me to avoid damaging the board with a regular socket. Users installing something like this for the first time might want to use an X pattern to tighten each side down a little at a time, I went diagonal to tweak them all down with equal pressure on the chip.

  

As you can see in the picture, there’s an issue here for my board at least, the fins of the Hyper 612 PWM actually float over the RAM which makes installation or removal a task in itself. While this might not apply to all boards, it does mean a full removal and installation job again for any upgrades. It’s a small sacrifice for something this large and powerful, let’s look over at the performance charts to see how well it held up, also note that if you have a side fan on your panel hovering over the CPU, that will need to go or be externally mounted. The cooler actually comes to the end of the case in the Phantom making it impossible to  internally mount a large fan and the 612, I had a 250mm fan from a Skeleton mounted inside the case originally which was removed for testing.

Performance

Benchmarking ran with a specific set of rules, HyperPI to 12M to measure load peak under the stress of the program. Fan control managed with the AMD internal controller at 26% to 100% forced fan load for each unit and in overclocking. Idle temps were taken after letting the system sit for 90 minutes between tests to let the CPU cool between uses and reach a temp that did not fluctuate.

What you can see in the charts is a pretty nice leap, there’s a sharp decline from the OEM to the Black Edition at low performance use  but the gap widens as load hits. For those gaming it’s a bigger jump as the Stock Cooler jumped all the way to 59c at low-speed and struggled at 55c at high-speed, the Black Edition brings the temps lower but we’re measuring with a room controlled at about 19c, in the summer or well insulated rooms it could jump even higher. We see the Hyper 612 PWM step in against the stock chip with hard cooling even with the VCore up .150 and a 400MHz increase during overclocking. Granted the 9750 isn’t the best chip to compare with, it was difficult getting the core stable for benchmarking so I we would see better results on a newer Deneb, Thuban or Zambezi chip. The point though is taking it to extremes on that chip still couldn’t break 55c in a cold room.

I will note the chart doesn’t include the OC results for the stock cooler and Black Edition as the heat output was too high to test with for stability. With the stock cooler clearing 60c under load it was unsafe to proceed.

Noise

The 612 rarely gets above the mid-30’s while in regular use, as a result the noise factor isn’t really a factor at all. When cranking the Phantom fan controllers to low, the system comes to a hum with the GPU actually making the most noise in the case. At idle, the 612 sits at 1300 RPM according to the readings and when pushed at max speed I peaked at 1880 RPM and even then it was just a deep hum in the case. Because the fan is so thirsty, it does demand that some cooling is present in the case, I do advise at least having 1 fan push in air for the case to keep the pressure coming in, depending on the choice, it may raise case noise slightly depending on your situation.

  

Conclusion

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.

For those who want to gain an extra 3-4 degrees off of the cooler, adding another fan to pull the heat out faster would work wonders but it does require an extra investment. For those who don’t want the quiet factor of the 612, there’s the option to upgrade it to a high flow push-pull configuration to probably knock even more than that off. For modders though, the 612 can’t be done justice in these photos, it ‘s a raw beast you’ll want to showcase. Instead of having covers surrounding it you just have bare metal and a huge fan. Strap on a few LED fans for extra light and you’ll really have a showcase going with this setup, the stock fan is great but there’s always room to improve.

The NZXT HAVIK 120 arrives

That is a lot of capital letters, the NZXT HAVIK 120 is here though and aiming to fit into some extra markets out there, with a smaller profile design and smaller fans it aims to tackle areas that they couldn’t reach with the 140 series. As someone who has an Antec Skeleton in their lineup I can say that sometimes you really do need something a little lower profile. Even my NZXT Phantom requires a bit of extra space due to the 250mm Antec fan mounted to the side panel opening. Coolers like the V10 and such tend to a little too tall for that setup.

NZXT uses their long-life 13 blade 120mm fan in push-pull configuration to cool the nickel-plated copper beast down at a steady 75cfm, the 8mm heatpipes cool and pump heat out of the socket base to keep things regulated and efficient. Overall it’s sleek and the nickel has a great finish to it. Given my impressions from the Phantom review I can only hold high hopes for this latest release. If we get lucky and catch a review of it I’ll go through the full details of the cooler and how it stacks up. In the meantime just check out the specs listed from NZXT and a nice gallery about the HAVIK 120.
