CPU Cooler be quiet! Pure Rock 3 Black CPU Cooler - BK039

be quiet! Pure Rock 3 Black (BK039) is an air cooler for CPU, aimed at mid-range and more serious gaming and work configurations. With a cooling capacity of up to 190W, it easily handles loaded processors without gasping during long gaming sessions or rendering. The black design makes it unobtrusively stylish, and the set with two 120 mm fans gives you better control over temperature and noise. You get a combination of reasonable size, serious capacity, and flexible compatibility with modern sockets.

What you get

With air cooling and capacity of 190W, this cooler is a comfortable choice for modern multi-core CPUs that are heavily loaded in gaming and productivity. The two 120 x 120 x 25 mm fans can spin from 200 to 2000 RPM, which means that under light load they can operate almost silently, while under load they provide a massive airflow of up to 59.6 CFM. The maximum pressure of 2.41 mmH2O helps the air to pass effectively through the radiator, rather than just “crashing” into the blades. The noise level of up to 31.2 dBA is completely acceptable for a gaming machine, especially if you set an aggressive fan curve only at high temperatures. Thanks to the standard 4 PIN connector, you can rely on PWM control through the motherboard and adjust the behavior according to your preferences.

• Air cooling with a capacity of up to 190W, suitable for loaded gaming and work processors.
• Two fans sized 120 x 120 x 25 mm provide better cooling and smoother airflow through the radiator.
• Wide speed range of 200-2000 RPM allows quiet operation in idle and aggressive cooling under load.
• Maximum airflow of 59.6 CFM helps maintain stable temperatures even in warmer cases.
• Static pressure of up to 2.41 mmH2O makes the fans effective in dense fins and more compact cases.
• Noise level of up to 31.2 dBA is well balanced for a system you want to be quiet, but not sacrificing cooling.
• Compatibility with sockets AM4, AM5, LGA 1700, LGA 1851 and older LGA 1200/115x gives you freedom for future upgrades without a new cooler.

Who it is suitable for

Pure Rock 3 Black is suitable for gamers and power users looking for stable air cooling for mid-range to stronger CPUs, without moving to huge towers or water cooling. It is a good choice for configurations for 1080p/1440p gaming, streaming, and multitasking, where the processor often stays under load. If you are chasing extreme overclocking or a completely silent system under load, there are more niche solutions, but for a normal and reasonable high-performance build, this model is very balanced.

The combination of 190W capacity, two 120 mm PWM fans, and wide compatibility with modern sockets makes be quiet! Pure Rock 3 Black a practical and long-term choice for a serious but well-measured gaming or work computer.
