The be quiet! Pure Rock Pro 3 LX is a double-tower air cooler with two Light Wings LX 120mm PWM fans, six heatpipes and ARGB lighting. It comes in at #8 in our CPU air cooler guide. The listing gives a 4.6-star rating from 193 reviews, yet the review histogram only accounts for 100 of them (5 one-star, 3 three-star, 9 four-star, 83 five-star). The same listing pairs a 250-watt figure with a 12-volt 4-pin fan, a combination that does not add up as power draw.

Everything on this page comes from the Amazon listing for this product and not from our own testing. We have not measured the cooler, and we cannot verify the 250-watt or 34.8-decibel figures beyond what the listing states.
