The be quiet! Pure Rock Pro 3 is a double-tower air cooler sitting at number four in this guide. The listing gives it a price of £41.98 and a rating of 4.7 from 322 reviews, six 6mm copper heatpipes on a nickel-plated base, two 120mm Pure Wings 3 PWM fans named in the item highlight, a maximum fan speed of 2000 RPM, a noise figure of 34.8 decibels, and item dimensions of 13.9 x 12.4 x 15.5 centimetres. That last figure is the one to check against your case before ordering: 15.5cm of height, with the listing noting the front fan's height can be adjusted if needed.

The reason it lands here rather than higher is what its own specification table says. This is the be quiet! cooler that shares its £41.98 price with the other Pure Rock Pro 3 entry in this guide, and this is the one whose Wattage field reads 3.6 watts; the other reads 250 watts. Both are listed with a 12 Volt, 4-Pin fan connection, so 3.6 watts is the figure that matches the hardware in the box — 250 watts in that field is cooling capacity lifted from the product copy, not the power the cooler draws. The same table disagrees with itself on quantity as well: Number of Packs says 2 while Number of Items says 1, against two fans in the item highlight and single-fan wording in the bullets. Everything on this page comes from the Amazon listing, not from any testing of our own.
