be quiet! Shadow Rock Slim CPU Cooler Review

Performance

The Shadow Rock Slim offered up pretty moderate performance in our stock tests, nothing really note worthy here but certainly enough to keep our i5 3750K well within a safe margin, even when under heavy load.

Interestingly the Shadow Rock Slim is on par with the much more expensive Dark Rock Pro 3 in our overclocking tests. This is very surprising, but I think the difference would really start to show if you’re pushing your CPU clocks even higher, as the Pro will handle a lot more heat in the long run.

It wouldn’t be a be quiet! cooler if it wasn’t one of the quietest we’ve ever tested, just a little quieter than the Dark Rock Pro 3, and so it should be since the Pro has two 135mm fans, the Slim only has one. 39dBa is barely a whisper above the 36dBa ambient I recorded while testing this cooler.

Overclocking test done and the Shadow rock Slim is the quietest fan equipped coolers I’ve ever tested. In fact I really love this chart as it shows just how quiet be quiet! can be, given that the Shadow Rock, Dark Rock Pro 3 and the Dark Rock 3 are the top free on this chart for low noise, aside from the NoFan which is a passive cooler.
