About Cooler Master

Cooler Master has long been a staple of PC Cooling, and is well known amongst PC enthusiasts. This summer has been busy for them, with many new releases. This year I’ve reviewed their MA824 Stealth and Hyper 622 Halo air coolers for Tom’s Hardware, which I found especially strong when set to low noise levels. I’ve also recently tested their newest 360mm AIO liquid cooler, the 360 Atmos, and found it to be tied for the best 360mm AIO on the market.

Today’s review will feature the latest revision of the 212, Cooler Master’s Hyper 212 Black with SickleFlow 120 Edge fan. The cooler’s design has been refined for better performance with the latest Intel and AMD platforms. But are these improvements enough to handle the heat of a modern processor, like Intel’s i7-13700K? I’ll show you how well it performs in the benchmarks, but first lets take a look at the installation and specifications of this cooler.

Features of Cooler Master’s Hyper 212 Black

Model RR-S4KK-25SN-R1
RAM ClearanceUnlimited
ColdplateDirect Touch Copper Heatpipes intertwined with Nickel (?) Coldplate
Heatpipes4 Direct Touch Copper Heatpipes
Dimensions125 x 74 x 152mm
Compatible SocketIntel Socket LGA 115X / 1200 / 1700

Low Height, Single Tower Heatsink

The Hyper 212 Black utilizes a single tower heatsink with nickle plated, jet black stacked fin arrays for thermal dissipation. It should fit into pretty much any normal sized computer case with it’s low height of 152mm.

4x Direct-Touch Heatpipes

The Hyper 212 Black features 4x direct-touch copper heatpipes integrated into the coldplate for efficient thermal transfer.

Full RAM Compatibility

The Hyper 212’s fan doesn’t overhang DIMM slots, ensuring full compatibility with any size of DDR4 or DDR5 modules no matter how tall they are.

1x 120mm SickleFlow Edge fan

There’s more to a cooler than just it’s heat sink, the fans paired with a cooler have a huge impact both total cooling potential and noise levels. Included with the Hyper 212 Black is Cooler Master’s SickleFlow 120 Edge fan. This is a seven-bladed fan with rubber anti-vibration and it seems to have good quality construction based on a quick inspection of the unit, there are no obvious signs of flaws or weaknesses.

This model of fan has been optimized for static pressure and lower noise levels, maximum system noise measured 42.4 dBA with this cooler installed. It features auto-start/stop, which means that the fan stops spinning entirely at the lowest PWM levels and only engages when it’s really needed.

Size120 x 120 x 25
Speed690-2500 RPM ±10%
AirflowUp to 70.7 CFM
Static PressureUp to 3.61 mm H20
Rated Noise Level32.8 dBA
BearingLoop Dynamic Bearing
Connector4-pin PWM

Tube of CyroFuze Thermal Paste

While many competitors only include pre-installed thermal paste, Cooler Master included a tube of it’s signature CryoFuze thermal paste with the Hyper 212 Black that will suffice for multiple installations.

Packaging and included contents

The Hyper 212 Black arrives in a small box just large enough to hold the contents, with molded cardboard and plastic for the protection of the inner contents.

The fan, heatsink, and accessories are each protected by a different piece of cardboard.

Included with the package are

  • Single Tower Radiator
  • 1x 120mm SickleFlow Edge fan
  • Mounting for modern Intel & AMD platforms
  • Thermal paste
  • Manual
  • Fan Clips for two fans

LGA 1700 Cooler Installation

The installation of the Hyper 212 Black is very simple, requiring only a few steps. It’s essentially the same process on both Intel and AMD systems. First, you’ll start by securing the mounting brackets against the bottom of the cooler.

Next you’ll need to take the CPU backplate and press it against the rear of the motherboard.

After applying thermal paste to the CPU, take the heatsink and screw the mounting brackets into the backplate. You’ll need to use one hand to keep the backplate in place while connecting the heatsink, as there are no standoffs in this design.

The last step is to secure the fan to the heatsink using the included fan clips, and then connect the fan to the motherboard’s PWM header.

Intel i7-13700K Thermal and Acoustic Results

Maximum Cooling Performance

Running Cinebench without power limits enforced is difficult to cool, and most coolers are unable to keep the CPU under it’s peak temperature in this scenario – so we’ll be looking at the maximum watts dissipated by the cooler in this situation.

With an average of 212 watts cooled during testing, the Hyper 212 Black provides basic cooling performance slightly better than Thermalright’s Silver Soul 135 and Scythe’s Kotetsu Mark 3 – but falling behind DeepCool’s similarly priced competitor, the AK400 Digital.

Maximum Noise Levels

Cooler Master’s Hyper 212 Black achieves its maximum cooling performance with total system noise levels of 42.4 dBA, a result quieter than most coolers on the market. This level of noise is audible but not loud, and shouldn’t bother most users.

Some of y’all might notice that the graph starts at 35 instead of zero – this is because my sound meter cannot measure noise levels lower than 35 dBA. Since that is the noise floor of this meter’s recording capabilities, 35 dBA is the “zero” for our testing purposes. For those concerned that this might distort results – there’s no worry. If anything, the graphs above will minimize the differences in noise levels because dBA measurements are logarithmic.

For a more detailed explanation of how decibel levels correspond to perceived noise levels, please check out the video below from BeQuiet! which makes it easy to visualize and understand the true impact of of increasing dBA levels.

Noise Normalized Results

While maximum performance testing is nice, a lot of folks prefer run their systems quietly. This can result in some performance loss in the most power intensive workloads like rendering. In this test, we’ve set the coolers so that system noise level measured at 38.2 dBA.

The Hyper 212 Black did better in this noise restricted test than it did early, with an average of 199W cooled during testing it fell just a few watts behind DeepCool’s AK400 Digital, but outperformed dual tower coolers from Jiushark and Cougar.

Included below are results with additional coolers that I’ve tested for Tom’s Hardware. As the results below were tested in the same system, by the same person, in the same location – they are 100% comparable to the results above. If you’re interested in seeing more of those results, check out my latest reviews there.

175W Thermal & Acoustic Results

Most loads that common users run won’t use more than 200W, so this is a better analogue for a worst case scenario of what folks might actually see in day to day usage.

With a thermal measurement of 60C over ambient, the Hyper 212 Black does well – performing on par with dual tower air coolers like Thermalright’s Peerless Assassin and Juishark’s JF200S.

Noise levels are slightly more important than thermal results in this scenario, and the Hyper 212 Black’s result of 42.4 dBA is fairly good here – on par with Scythe’s Kotetsu Mark 3, but quieter than Thermalright & Cougar’s coolers.

125W Thermal & Acoustic Results

When restricted to 125W, thermal performance really isn’t a concern – though I’ve included that information in the graph below. Really, any cooler should be able to handle this load – even Intel’s stock cooler!

With a temperature of 45C over ambient, the Hyper 212’s thermal performance is only a single degree behind the best results we have from other air coolers. But really, thermal performance isn’t a concern at this lower power limit – noise levels are more important.

All of the coolers tested achieved good acoustic levels here, but Cooler Master’s Hyper 212 Black was so quiet that it ran quieter than the system fans with total system noise levels of 37.3 dBA. What this means is that in low intensity workloads, you’ll never hear the sound of the cooler’s fans in most modern computer cases.

Cooler Master’s Hyper 212 Black shows that with a few refinements, this classic cooler is still capable of handling modern processors. It’s SickleFlow Edge fan runs quietly while providing adequate cooling performance. My only complaint about this cooler is that it is slightly overpriced at $39.99, when most of it’s competitors are around $30 USD.

If you’re interested in this cooler, it releases in three days on October 10. You can find it on Amazon and other fine retailers, but be aware that the current pre-order prices are inflated. You’ll want to wait until it’s actually released to find it at it’s MSRP of $39.99
