RR-AM4B-H212-S1 Manual

Top choice bracket to mount your cooler with

CoolerMaster is a computer hardware company founded in Taiwan in 1992. They specialize in manufacturing cooling systems, power units, computer chassis, chassis fans, docking cradles and many other accessories for laptops and gaming hardware for cyber sportsmen. Some of CoolerMaster’s top-of-the-line products include implements for cooling system installations. Cooler Master RR-AM4B-H212-S1 is an adapter meant for the AM4 socket. In this article we’ll take a look at some specifics of its installation procedure along with benefits/disadvantages of tower-style cooling systems.

Specs and compatibility

This AMD AM4 upgrade kit is designed for a series of processors including Intel and AMD Ryzen. The adapter itself is made of 1.5 mm stainless steel, and the installation tools supplied show good durability and can be used multiple times.

Compatible systems include some products of the MasterAir and Hyper series. Those are useful for high-performance gaming and streaming builds, mining rigs, and for overclocking purposes. Those users who are not comfortable having a liquid cooling device in their machine essentially have to look no further. The kit speeds up and eases up the process of cooler installation, coming to be a perfect choice for PC owners with little or no technical skill. As soon as you install your cooler, it will keep your machine running extremely cool. For instance, paired with a Ryzen 5 2600, the chip has been reported to idle at no more than 75 °F (24 °C). The installed cooler will be easy to clean with a can of compressed air, while  running quietly and keeping your PC’s core at a stable cool temperature under heaviest load.


To illustrate the ease and promptness of the installation process, we should evaluate it using the example of CoolerMaster’s Hyper 212 EVO CPU cooler.

This tower-style cooling device features a direct-contact heat-pipe design and targets the mid-range segment with its price of around $35 USD. User reviews tell us that this EVO model enjoys popularity among enthusiasts interested in getting their rig to operate quieter or have some extra overclocking headroom. With its overall weight of moderate 1.25 lb (569 g), the model’s heatsink has pretty standard dimensions of 6.3 in (160 mm), with 0.2 in (6 mm) of copper heat-pipes exposed from its base.

The installation process with the RR-AM4B-H212-S, although pretty straightforward, is best conducted when you get to understand it rather than simply follow the instructions. It is recommended to use both the images/written directions provided in the user’s manual and some quick YouTube tutorial. Since it supports a variety of processor and socket types, variations in the installation procedure need to be cleared specifically for your cooler model.

Overview of the manufacturer’s instruction

Basically, with the use of this kit your cooler can be simply clipped in the bracket mounted onto the motherboard’s retention module.

Step #1. You will need to unscrew the retention module from your motherboard, while leaving the plate on its bottom untouched. The way you choose to orientate the bracket relative to the motherboard does not matter.

Step #2. Secure standoffs to the CPU zone on the motherboard.

The bracket fits on any standard AMD backplate and uses the standard screws. On the second step in the installation process, you need to apply four stand-off bits to the motherboard’s socket plate.

Step #3. The bracket goes just between the heatsink and copper base. To place it in the AMD configuration, you must unfold the bracket for the eyelet to line up with the ‘I’. Pay attention the locator point from the copper base.

Step #4. Mount your cooler onto the standoffs. Remember that you need to remove the protective label from the copper base before installing the cooler. Also, ensure that you’ve screwed on the mounting plate to the rear of your PC’s motherboard before detaching the CPU cover and greasing it with the thermal paste.

Step #5. Now you can replace the fan back onto the cooling system. Don’t forget to check if you’ve plugged the fan cable into your PC’s motherboard.

Some notes on the installation process

Of course, CoolerMaster’s manual does not mention it, but you will actually be able to do better using a partner’s help. When installing the backplate along with the GPU, you’ll have to ensure that the bolts match specific areas on the layout. Depending on how adroit you are with a screwdriver, the components may give you a hard time falling out of place and shifting.

Another thing to be aware of is the pressure you apply between the CPU and the motherboard with your cooler’s heatsink. Some users have reported bent pins on their motherboard in the result of heatsink mounting; specifically, this problem has been mentioned with the Hyper 212 EVO model.

The following may come in handy when placing any supported cooler with this upgrade kit:

  • Install the bracket/cooler system on the motherboard before assembling your PC (applicable, if you are building a PC from scratch). With some chassis, screwing the bracket on is harder in the fully assembled configuration.
  • Another good idea to get better access to the screws would be declipping the fan from the heatsink before installation.
  • The cable designed to reach the CPU fan header may be a bit too long. To fix this, you can wrap it around the outside of the cooler fan and use a small patch of electrical tape to attach the excess cord to the fan chassis.
  • In case you have a pre-built PC, be ready that upgrading your stock AMD fan/heatsink may cost you some time. That could mean removing the motherboard from the case, detaching everything on it, and unplugging all the cables. Only then you will be able to remove the existing retention bracket and mount the new one.

Why choose tower-style coolers?

Comparison with water cooling

The hugest upside to any tower-styled cooling product as compared to liquid CPU coolers is the price/effectiveness ratio. Being quite affordable, the air coolers beat at their price point those liquid ones that cost twice as much. There are users out there whose demands to the CPU performance have only been satisfied after they replaced their water cooling systems with an even cheaper tower-design cooler. This solution works for smaller chassis just as well, because those coolers also exist in a mini-tower version.

The economic benefit becomes even more obvious when extended to cryptocurrency mining rigs. You be able to cool down lots of your CPUs while doing it quietly. The temps should not go higher than the lower 60s even at highest continuous loads. Overall, this much cooling helps you lower the voltages and troubles you with fewer points of failure at the same time.

Advantages and disadvantages

Let us return to our exemplary EVO model. This tower-design cooler is used in a variety of builds with most satisfactory results. The steel bracket makes it fit perfectly providing you with reliable basic cooling that’s beats the stock CPU fan by far. Unless you want to pull off some crazy overclocking, air cooling with this tower unit will keep your system chilled, and you won’t have to shell out for a top-notch liquid cooler.

The Hyper 212 EVO boasts POM bearings that are quite longer lasting and fully dustproof.  Like all tower-style coolers, she is designed to distribute heat up to eight times faster than stock CPU heat-pipes, which allows the CPU to eliminate hotspots and promptly balances the heat volume between all heat-pipes. The tight conducting contact with the core here is meant to ensure the best heat transfer; each of the 6 mm heat-pipes is placed directly across the CPU. This configuration enables the cooler both to react promptly to changes in thermal load and distribute the heat up the towering unit.

Briefly put, the advantages are as follows:

(+) Pretty inexpensive.

(+) Suitable OEM replacement.

(+) Greatly improves airflow.

(+) Tight core contact design with durable construction.

(+) Dual fan support. You can attach a second fan if your rig still isn’t cool enough.

(+) Large heatsink and removable fan.

(+) Up to 68 °F (20 °C) lower temps in comparison with the AMD stock cooler.

(+) Simple installation for those familiar with assembling a computer.

However, users also point out several disadvantages, namely:

(-) Cumbersome installation that may feel difficult due to confusing manufacturer’s instructions.

(-) Even though this and other tower-style cooler are compatible with various cases, be sure to check if your particular case can fit it—those units are VERY large.

(-) Some think that this kind of hardware could use a more powerful fan.
