Black-finish air cooler for mainstream desktops

The Cooler Master Hyper 212 Black uses four direct-contact copper heat pipes and a 120 mm PWM fan to move up to 70.7 CFM of air. A nickel-plated black fin stack and aluminium top cover give a uniform dark appearance. The unit mounts vertically and stands 152 mm tall, fitting standard mid-tower layouts.

Check socket, height and fan header before ordering

Your motherboard must use one of the listed sockets: AMD AM4 or AM5, Intel LGA 1150, 1151, 1155, 1156, 1200, 1700 or 1851. Verify that the case allows at least 152 mm of cooler clearance and that a 4-pin CPU fan header is available for PWM control. The cooler weighs 1.54 lb, so ensure the mounting area is secure.

Thermals, noise and power in normal use

The SickleFlow 120 Edge fan spins between 690 and 2500 RPM, producing a maximum noise level of 32.8 dB(A) and 3.61 mmH₂O static pressure. Power draw is rated at 2.4 watts on a 12 V supply. Supplied CryoFuze paste rated at 14 W/m·K helps maintain stable temperatures across the operating range.

Questions about this item

What comes in the box with the Hyper 212 Black and is thermal paste included?

The package includes the heatsink with four copper heat pipes, a 120 mm SickleFlow Edge PWM fan, mounting brackets for AMD AM5/AM4 and Intel LGA 1851/1700/1200/115X sockets, and a tube of CryoFuze thermal paste rated at 14 W/mK.

Which version of the Hyper 212 Black should I choose for an Intel LGA 1700 or AMD AM5 build?

This single model RR-S4KK-25SN-R1 supports both platforms out of the box; the redesigned brackets cover Intel LGA 1851, 1700, 1200, 115X and AMD AM5, AM4, so no separate version is needed.

How does the 70.7 CFM airflow rating translate to actual cooling on a modern desktop CPU?

At full speed the 120 mm fan moves 70.7 CFM with 3.61 mmH₂O static pressure, enabling the four direct-contact heat pipes and aluminium fin stack to dissipate typical mid-range CPU loads while staying near the quoted 32.8 dB(A) noise level.
