BeQuiet! Pure Rock Pro 3: Dual towers in the entry-level class

Cooling, CPU coolers, Extra tests | | Ľubomír Samák

An above-standard fin surface area is what characterizes the latest Pure Rock (3) coolers with the “Pro” designation. That “Pro” refers to the pair of fin stacks that the heatsink is composed of. And yet, we’re still in the lowest product line that BeQuiet! offers. The tested variant is also the least expensive of them all. Grey fins (without a black coating) and “ordinary” fans (no lighting) – that’s the Pure Rock Pro 3 with the product code BK041.

Results: Very low noise level (33 dBA)







Spectral analysis of noise

Why is there a missing value in the chart? The reason is that the cooler could no longer handle the load in the specified mode. Control to lower noise levels fails for reasons such as an overly noisy liquid cooler pump or a whining fan motor.
