Pure Rock 3 is ready for modern flagship CPUs like Intel's Core i9 or AMD's Ryzen 9 series.

KEEP IT COOL

Very high cooling performance

Pure Rock 3 Black is aimed at consumer PCs. With 190W TDP it offers an excellent cooling capacity for gaming, multimedia and graphics systems, as well as mainstream or entry level computers of all types.

HIGH-PERFORMANCE HEAT PIPES

Ensuring perfect heat transfer

Pure Rock 3 Black is equipped with 4 black 6mm heat pipes, matching the color of the heat sink. The heat pipes are key to the cooler’s great cooling performance, because they transport the heat to optimum locations on the cooling fins. They do so with minimal bends and high bending radius, to maintain the performance of each heat pipe as good as possible.

OPTIMIZED TO THE MAX

For unprecedented air pressure in its class

Pure Wings 3 120mm PWM and Pure Rock 3 Black are a perfect match. The fan features optimized fan blades for highest performance. The angles are adjusted to achieve even more air pressure, adding up to the extraordinary performance. A specially designed, funnel shaped air outlet is more than just the icing on the cake: it maximizes the airflow over the fins.

MULTIPLATFORM

Second to none compatibility

The Pure Rock 3 Black's slim design increases RAM and VRM cooler compatibility significantly and enables limitless memory height. Thanks to its compact construction Pure Rock 3 Black is the perfect choice for PC cases that have limited space. Notwithstanding, it allows full configuration of RAM banks.

SUPER EASY INSTALLATION

No tutorial needed

Installation is easier than ever with the Pure Rock 3 Black. Thanks to its convenient, preinstalled mounting bridge plus screws and a firm yet gentle fixing method, cooler attachment is a breeze. Users of an AM5 CPU by AMD can benefit from an offset mounting to center the heat pipes above the hot spots of their CPU.

DESIGN UPGRADE

Who says that neat looking products must be expensive? Pure Rock 3 Black comes in an unmistakable all-black design that sets a statement in your PC: this air cooler is here to stay. Every little detail is carefully arranged, making Pure Rock 3 Black a design gem in its class.

LOADING...

The be quiet! Pure Rock 3 Black is a 120mm tower-style CPU air cooler for compatible Intel LGA 1150–1851 and AMD AM4/AM5 systems, suited to builders seeking capable air cooling in a clean, all-black design.

Recommended For

  • Mainstream gaming PC builders using a Ryzen 5/7 or Core i5-class CPU who want a single-tower air cooler for typical gaming loads rather than flagship-level thermal headroom.
  • PC builders fitting a tower cooler into a case with at least 154 mm of CPU-cooler clearance who want a slim design that leaves room for RAM and VRM heatsinks.
  • Home and gaming PC users who prefer air cooling and can use a PWM fan curve to keep noise down during lighter workloads; testing found noise drops substantially when fan speed is reduced.
  • Builders assembling an understated black PC who want a matching air cooler without adding RGB lighting.
