The Shadow Rock Slim is, as the name indicates, a slim CPU cooler, but as it uses a traditional tower design and a large fan, it's in no way petite. It's essentially be quiet!'s take on the Noctua NH-U14S, a sleek tower designed not to interfere with memory slots and board components close to the CPU socket, without compromising performance. It doesn't utilize a 140 mm fan, however — the stock fan falls 3 mm short of that diameter. Surprisingly, the size isn't even the most interesting thing about it; its oddly placed mounting holes and heavily ridged blades stand out even more.


The Shadow Rock Slim.

The heatsink itself uses fewer materials, forgoing the heavy top-to-bottom nickel-plating adopted by Noctua and other high-end heatsink manufacturers. The resulting product is lighter and more affordable but that doesn't necessarily mean it's an inferior cooler. The Thermalright HR-02 Macho and Scythe Mugen 4 proved that a more traditional unplated composition can be just as effective. be quiet! claims the Shadow Rock Slim can adequately cool a CPU with a TDP of 160W which isn't too far-fetched assuming there are no base or mounting problems.


The box.


Contents.

Inside the box is the heatsink and fan, a brief assembly guide, a tube of thermal compound, a backplate and necessary mounting hardware, and a second set of fan clips. Interestingly, the two sets of fan clips are not identical — the pair pre-installed are of course, designed to be used with the unusual placement of the stock fan's mounting holes. The additional set of clips are actually bigger, made to accommodate a standard 120 x 25 mm fan. This presents a dilemma for users who wish to run a dual fan configuration.

Our last experience with a be quiet! heatsink, the Dark Rock 2, was plagued with problems. We went through several samples that gave us poor results each and every time. After extensive testing we eventually concluded an inconsistent, non-flat base was the issue. Undeterred, the manufacturer has sent us another cooler to review, a newer, smaller model, the Shadow Rock Slim. We can only hope it doesn't suffer from the same issue.
