190W TDP air cooler for consumer PCs

The Pure Rock 3 Black is a single-tower CPU air cooler rated for 190W TDP. It targets consumer desktops used for gaming, multimedia and graphics work as well as mainstream or entry-level builds. Four black 6mm heat pipes with direct-touch technology transfer heat from the integrated heat spreader to the aluminium fin stack. A 120mm Pure Wings 3 PWM fan with a funnel-shaped outlet pushes up to 59.6 CFM at 2000 RPM while peaking at 31.2 dBA.

Check socket, height clearance and RAM space

Verify that your motherboard uses one of the supported sockets: Intel LGA 1150, 1151, 1155, 1200, 1700 or 1851, or AMD AM4 and AM5. The cooler stands 154mm tall, so confirm your case allows at least that much CPU cooler height. The compact 124mm-wide heatsink and vertical fan mounting leave room for tall memory modules and VRM heatsinks, but measure your specific layout to be sure. A pre-installed mounting bridge simplifies installation on all listed platforms.

Sustained load at 190W with 31.2 dBA peak

Under continuous load the cooler dissipates up to its 190W TDP rating while the fan spins to 2000 RPM, delivering 101.2 m³/h airflow and 2.41mm H₂O static pressure. The rifle-bearing fan maintains the 31.2 dBA noise ceiling even at maximum speed, so acoustic output stays predictable during long rendering or gaming sessions. The all-black aluminium and copper heatsink with four heat pipes provides consistent thermal mass without throttling.

Questions about this item

What comes in the box with the Pure Rock 3 Black and is any extra hardware needed?

The cooler ships with a pre-installed mounting bridge, four black 6 mm heat pipes, a Pure Wings 3 120 mm PWM fan and the brackets for Intel LGA 1700/1851 and AMD AM5/AM4. No separate mounting kit is required for those sockets.

Which version should I choose for a 190 W TDP CPU in a compact case?

This single 154 mm tall model supports 190 W TDP, fits cases with 154 mm cooler clearance and leaves room for tall RAM thanks to its 46 mm deep heatsink.

What does the 31.2 dBA figure mean when the fan hits 2000 RPM in a real build?

At full 2000 RPM speed the Pure Wings 3 fan produces a maximum of 31.2 dBA while moving 59.6 CFM, so even under heavy load the noise stays low.
