The Guru of 3D published a review on the Be quiet! Pure Rock SLIM CPU cooler
A quote from the article:
We test and review the be quiet! Pure Rock SLIM CPU Cooler. The cooler might not be the strongest performer on the block, but it is small, agile and intended for 'smaller' builds. Small or not, it is deadly silent but still packs enough punch to cool even a Core i7 4790K, albeit it's not an easy job for this one.Be quiet! Pure Rock SLIM CPU cooler review @ Guru3D
You know, there really aren't any bad performing coolers being produced anymore. For every segment and budget you can find something you need. The market stabilized and within the entire range and scope of heatpipe based coolers there's a certain comfort zone with a corresponding product available. As a result, most of the coolers available on the market are all adequate at the very least. There are always exceptions to this, there's a handful of manufacturers out there that offer the really interesting stuff, the kit and gear that really stand out from the cooling crowd, the hardware you and me crave and need so badly... that is in the enthusiast domain of gaming hardware. And that's where we need to make a stop at Be Quiet! as they tick boxes man!
