Powerful cooling in small spaces

The compact design achieves excellent heat dissipation in small spaces, making the Dark Rock Slim the perfect solution for high-end builds with limited space. Due to its compact construction no memory slots are blocked.


Only 23.6dB(A) even at 100% PWM fan speed

The Silent Wings 3 120mm PWM fan features seven airflow-optimized fan blades, a six-pole motor for less vibration and a durable fluid-dynamic bearing. Decoupled fan mounting with vibration-isolating elements on the heat sink.


Achieving an incredible performance-to-noise ratio

Dark Rock Slim provides an impressive rating of 180W TDP and achieves low temperatures even during periods of peak CPU performance. It is also possible to add another 120mm fan for even better cooling.


The core features that result in high-end cooling

Dark Rock Slim is equipped with four advanced technology 6mm copper heat pipes that maximize the heat conductance. Airflow-optimized, wave-contoured cooling fins with small dots on their surfaces increase the air circulation. The special black coating with ceramic particles makes a perfect transfer of heat possible.

Questions and Answers

Do you have you a question about the Be Quiet Dark Rock Slim Air Tower CPU Cooler?

Q: Can this be mounted on the stock backplate on an B450 motherboard (in this case ASUS ROG STIX B450-F)? I'd like to avoid removing the motherboard from the case if possible. I have the original plastic clips which can be re-attached to the plate.
Answer by Website User on 13th May 2020
You will not need to remove the backplate to install this cooler on an AM4 socket. -MR

Super quiet, looks good, can manage a high TDP CPU. Comes with 1 fan, but can attach a 2nd for push/pull config if desired. Only drawback I have found is it can obstruct graphics from being inserted in upper pcie slots on my motherboard, but this is probably a common issue with tower coolers in general.

Quality product, easy to fit. Would have welcomed some instruction on which way to face it within the case.

Quiet, looks understatedly great, and my ryzen 7 3700x is cool and comfortable. May be somewhat cheaper options but I don't regret picking this!

Lives up to it's name, cannot hear anything over my PC case fans,even when the cpu is under load.Keeps my cpu temps down and getting better performance because of it. Would highly recommend this cooler over any stock cooler.

Great cooler. It keeps the cpu cool and runs quietly. The design in sleek and build quality feels premium. It's amazing an air cooler can be this good.

Maybe a little more expensive than its closest rival (cooler master 212) but the build quality is excellent. Easy to assemble and fit (amd r3600) doesnt overhang the ram slots so no issues there. Idle temps around 30 degrees but i am running 6 case fans. It has a very understated look so blends in well with the rest of the build. Using a Corsiar icue 220t case and fits with no issues.
