COOLER MASTER Hyper 212X CPU cooler
Hyper 212X

A new addition to the widely acclaimed Hyper 212 series, COOLER MASTER Hyper 212X CPU cooler raises the bar for reducing the temperature of your AMD or Intel CPUs even higher. The aluminum fin array adopts X-Vents and Air-Guide to better expel heat away. Up to four direct touch heatpipes pass through the aluminum fin array to create a comprehensive cooling system. Thanks to the fan with redesigned blades, more airflow will be created to cool the heatsink without producing more noise. And the fan’s 4th generation bearing ensures an incredible lifecycle. With COOLER MASTER’s brand-new smart fan engine, the fan will stop once blocked to ensure exceptional protection.

Highlights
X-Vents Design

Positioned in a 45 degree angle and surrounding the heatpipe, each fin-blade features X-shaped vents that create areas of high and low air pressure, resulting in several controlled vortices. These small and chaotic turbulences produce strong gusts that reduce overall airflow but improve airflow where it matters the most – next to the heatpipes.

X-Vents Design
Exclusive “V” Shaped Array

Funnel shaped aluminum fins and a series of perforated dimples guide the airflow towards the heatpipes. The specially designed X-Vents act similar to tiny airplane wings and prevent deadspots behind and between heatpipes. The combination of both of these exclusive technologies results in notably higher airflow over the heatpipes and the adjacent fin area, which ultimately reduces CPU temperatures.

Exclusive “V” Shaped Array
Unique CDC Technology

4 Continuous Direct Contact Heatpipes create a gap-less contact surface for unmatched cooling efficiency.

Unique CDC Technology
Optimized Fin Design
Optimized Fin Design

Aluminum Fin Array with Tunnel Effect layout creates micro vortices that boost the airflow and circulate it around the heatpipes.

Supports All Current CPU Sockets

Fast and easy to install and extremely reliable, Cool Master’s famous X-Bracket mounting system is compatible with all current sockets.

Supports All Current CPU Sockets
POM Bearing

The POM bearing is coated with Polyoxymethylene material. This type of material is ideal for precision parts requiring high stiffness, and provides consistently lower friction levels than traditional bearings. Self-lubricating, lower friction, and dustproof protection, ensure the average lifetime is pushed up to an incredible 160,000 hours.

Good starter CPU Cooler 4/10/2019 1:35:32 PM

Pros: Quiet
Relatively small

Cons: Not quite as efficient as other coolers

Overall Review: I bought this to start my gaming PC build. It performs well for a basic cooler. I used mine on an i5-7600k which tended to get a little on the warm side. Mid 70 Celsius while gaming. I never had any problems with it for the year that I used it. But I did upgrade to an All-In-One cooler for longevity's sake. Now around the mid 40 Celsius mark for those that are curious. I would recommend this for those looking for a cheap CPU cooler that don't expect to overclock very much.

cools well 2/16/2019 5:13:20 PM

Pros: It cools the CPU great, keeps it around 23c normal use and around 30 during heavy gaming, Even under heavy load during benchmark trials this coolers does a good job, just as good as the closed loop overpriced junk. But for a normal gamer use, this cooler is great for a I56600K skylake overclocked to 4.1. I never saw the CPU go over 38 during FO4, CoD Black ops 3 or insurgency all settings were just about maxed out. Fan is very quiet My system is nearly silent and it sits next to me literally 1 foot away. LOL at the peeps that go closed loop water cooling,,there really is no need unless you are an extreme over clocker then obviously you wouldn't purchase a closed loop cooler but rather a Self built cooling system. I am a system builder with over 25 years of experience, the best cooling system is a constant air flow in and out...the only time water cooling needs apply is during extreme over clocking were temps can reach over 105c...other than that Water cooling is a total waste of time and money that could be properly used else were.

Cons: Install design puts the motherboard at risk of damage, especially the cheaper boards that are thin, you have to screw the standoffs into the back plate and there is nothing to protect the motherboard finish from the standoffs. SO be careful and don't torque them down to much. Directions like the other reviews said were absolutely useless. for me this wasn't my first rodeo so I new what to do by just looking at the design. If this is going to be your first build then there are a few videos on youtube that show you how to install this cooler I suggest you watch them if you are planning on buying this cooler and you are a first timer.

Overall Review: MSI Z170 mobo

this cooler.
The only reason I gave it 4 instead of 5 eggs was because of the install design, this will be the last cooler I ever buy from cooler master. I had to take a flat tip screw driver and spread the backplate mounts because the standoff screws would not fit in them. Cooler performs well but has Cheep Chinese knock off written all over it. Going back to Zalman yeah I know I'm sure they are made in china as well but at least they pay attention to quality control.

hard to assemble 10/11/2018 11:19:43 AM

Pros: looks nice, easy to remove the fan and clean the fins.

Cons: Assembly Instructions are minimal. One size fits all design means you get lots of parts, not all of which you
need, and it's REALLY hard to figure out how to mount it. Also, I used some fiber washers to protect the bottom of
my motherboard, which were not included.

Good, solid cooler at this price point 10/3/2018 11:16:03 AM

Pros: Efficient CPU cooler
Nice and quiet
Fairly easy to mount

Cons: Head spreader contact surface if not smooth- surface of it appears to be ground or sanded. Would be OK for a non-overclocked system; I polished mine to afford more complete contact.

Instructions are 100% pictorial and are not the easiest to use; would be difficult for a first time builder

Wow what differance 9/14/2018 6:21:11 AM

Pros: works better than expected. Using on AMD10 that was shutting down from overheating (cpu/apu temps over 165F) while playing graphic intensive games. After replacing stock AMD cpu cooler temps barely going above 100 F

Cons: Pictograph instructions may as well have been Hieroglyphs, made no sense. Found U Tube instruction video after watching, instructions then made sense (yes this was my first install of an aftermarket cooler)

Overall Review: Barely fit in the case but it does a fantastic job. Like the low price too.

Cooler master has never let me down for 2+ years 8/13/2018 6:24:02 AM

Pros: - Quiet as a fox
- Keeps my computer cold as ice

Cons: - No problems

Overall Review: If you're going for a micro-ATX build with restricted space, it will fit but it'll be work to get it in.

Very quiet 8/4/2018 7:17:33 AM

Pros: Quiet. Keeps CPU cool at around 30c to 40c even in the games. at rest 29c or lower. Very efficient. AMD 8350. Had a water cooler previously that had died H75. So figured would try this budget cooler. with rebate at 20 bucks u cant go wrong. Does the job. No point in spending 80 bucks for a 'fancier' cooler since this one works great. Have a 2nd fan i may put on it but really is not needed.

Cons: A bit of a pain to install if u dont have the back bracket already. Had the H75 bracket still on the back so didn't have to put in the one that came with this one, so didnt have to unmount the MB. Anyone else may have to to put the back bracket on.

Overall Review: yup.
