EXCELLENT COOLING EFFICIENCY
An exceptional price-to-performance ratio
Pure Rock 2 is aimed at the essential category of PC systems. With 150W TDP it offers an excellent cooling capacity for multimedia and graphics systems, as well as entry level computers of all types.
HIGH-PERFORMANCE HEATPIPES
Ensuring perfect heat transfer
Pure Rock 2 is equipped with four 6mm heat pipes that have aluminum caps. This is key to its great cooling performance, because they transport the heat to optimum locations on the cooling fins.
SILENCE-OPTIMIZED OPERATION
Only 26.8dB(A) even at 100% PWM function
The Pure Wings 2 120mm PWM fan with high-quality rifle bearing facilitates the best balance between cooling performance and silent operation. The nine blades of the fan are airflow-optimized to reduce noise-generating turbulence.
HIGHLY COMPATIBLE COMPACT DESIGN
Fits well into tight spaces
The asymmetrical construction does not block memory slots, saves space and makes Pure Rock 2 compatible with a full set of RAM modules. It is also very convenient to install, thanks to the fact you can mount it from above the motherboard.
BRUSHED ALUMINUM FINISH
Great visual appearance at first glance
A high-grade brushed aluminum finish and the aluminum caps guarantee a nice appearance and make the Pure Rock 2 look right in any case.
Pros: If you don't plan on heavy overclocking and want a quiet cooler than this may be the cooler for you. I recently built a computer with an AMD Ryzen 5 3600. It came with the wraith stealth cooler. It's an ok cooler until you stress the 3600. Leaving oc on Auto on my MB, 4200 Mhz, and running the latest versions of Intel Burn Test and OCCT it reached 88C and 86C. The fan was running at 2550 RPM and was loud. I read several reviews on the Rock 2 and most agreed that it sacrifices cooling power for quietness, so I purchased another 120mm Pure Wings 2 fan for a push-pull configuration. These fans are rated for 1500 RPM max. I ran the same tests and the max temps were 73C and 71C. The fans were running at 1450 and 1480 RPM. Due to the blade design they were still quiet.
Cons: The fan clips are a bit flimsy and the fans are still a bit loose and the fins on the cooler bend easily. When I stood my computer up the fans slipped down a bit. The back plate on my Asrock B550 MB will not stay in place unless you hold it from the back. So topside installation only is not possible.
Overall Review: As I said if you are only going to do light or no overclocking with a lower voltage CPU like the 3600 and want quiet then this will do; but there is a lot of competition out there in this price range that gives better thermal performance. I'm keeping mine at 4200 Mhz. CPU voltage was 1.325V, high enough for me. The case in the pic is a Corsair Carbide 110R with front and rear 120mm fans. Temps were recorded with the sides on.
