Be Quiet is well known for its silent cooling, with products like the Silent Base 802 Computer Case and Dark Rock Pro 4 CPU Cooler having raised the bar for quiet cooling performance. The company’s latest product to land on our test bench is the recently launched Pure Rock 2 FX air cooler. Like the previously reviewed Pure Loop 2 FX , this is one of Be Quiet’s new products from its FX line , featuring addressable RGB (ARGB) lighting.

Can the Pure Rock 2 FX live up to its name while looking good and keeping things cool, earning a spot on our Best CPU Coolers list? We’ll have to test it to find out, but first let’s take a look at the Pure Rock 2 FX specifications, direct from Be Quiet.

Specifications for the be quiet! Pure Rock 2 FX

Packing and Included Contents

The Pure Rock 2 FX comes in a small box, with foam cutouts and cardboard for protection.

Included with the package are the following:

• Single-tower Radiator
• 1x Light Wings 120mm PWM high-speed fan
• Mounts for modern Intel and AMD platforms
• Pre-applied thermal paste
• Information Leaflet

Cooler Installation

The installation of BeQuiet’s Pure Rock 2 FX wasn’t hard; the main steps are shown in the image from Be Quiet below. You’ll remove the stock mounts on an AMD motherboard, install the appropriate back plate with posts and washers, add the mounting brackets on the front of the board, which vary by platform and screw them down with four screws. Next, you place the cooler on your CPU after adding the mounting bar, line that up with the mounting brackets, and screw each side down with a screw. The fan gets installed via a pair of wire clips, and you’ll of course need to plug it in to your board, along with a header for the ARGB lighting.

New Testing Configuration

Cooler Features

• Mid-range price of $52.99
• 4x 6mm Heatpipes

• 52 Aluminum Fins
• All black radiator
• Copper heatsink with pre-applied thermal paste

• 1x Light Wings 120mm PWM high-speed fan

There’s more to an air cooler than just a heatsink. The fan included has a significant impact on cooling, noise levels, and performance. Included with Be Quiet’s cooler is a single Light Wings 120mm ARGB fan. A second pair of clips are also included, should you want to add a second fan for a push/pull setup.

Testing Methodology

Most of the coolers featured in this review wouldn’t be up to the task of cooling Intel’s Core i9-12900K without power limits enforced, so I’ve paired them with a more appropriate CPU: Intel’s i5-12600K. Since many of the coolers I’m testing below might be considered for use in SFF builds and for those wanting silent performance, I’ve tested Cinebench with three power configurations

Values shown are for the average CPU package temperature over the course of running the Cinebench benchmark. Peak temperatures will be a few degrees higher than the results shown below.
