Does it come with thermal compound?

Yes, it comes with a little tube of compound. If I remember correctly, it is supposed to be enough for 2 applications.

Will this fit an AM4 socket without having to buy a separate bracket or adapter?

Sure will! Just installed it on my MSI Tomahawk B450 motherboard four days ago. It uses the backplate that comes with the mobo, so it was the easiest and best fitting air cooler I’ve ever installed. Performance is stellar too, so I highly recommend it.

Will this fit a z170 mobo?

Depends on the motherboard and case. I'm using noctua nhd14 on my z170 and p8p67 motherboards, and this slim on my z390 xi code and another z390-e strix

Does this come with a thermal pad?

No, but mine came with a small tube of thermal paste (you can see it in the product picture). Buy your own if you don't trust what be quiet includes.

I don't see LGA 1150 compatibility listed, but other similar sockets are. Is this unit compatible with LGA 1150?

LGA 1155, 1150, and 1151 have as far as I know identical spacing and tolerances at all but the most extreme ends. This cooler should work on LGA1150 with no issues.

Does it support the new ryzen 5000 series processors ?

Yes, this will fit the AMD (AM4) mounting system.

Anyone know if indeed Intel Gen 10 LGA 1200 is supported?

Yes, it is. This page says it's supported, but once it arrives, the directions do not list it. I suspect it's because it wasn't released yet when they developed this product, but the bracket still fits, so they just updated the store page. I just installed it with my new LGA 1200 motherboard, and it's good.

Adding a second fan help performance ?

Yes it will, it would be best to match up and get the same Be Quiet fan.

The be quiet! Dark Rock Slim BK024 is a compact, black CPU air cooler with a 120mm PWM fan and four copper heat pipes, suited to builds needing quiet cooling while preserving memory-slot access. It supports listed Intel and AMD sockets; LGA 1700 requires an additional bracket.

Recommended For

Quiet-focused builders using a mainstream CPU for everyday work or gaming who want low cooler noise without switching to liquid cooling; reviews found the Dark Rock Slim notably quiet under load.
PC builders with tall or fully populated memory who need a tower cooler that leaves RAM slots accessible; be quiet! positions the slim layout as avoiding blocked memory slots.
Builders choosing a single-tower air cooler for a space-constrained case who have verified that the case supports its approximately 159 mm height.
Users running stock or moderately demanding mainstream CPUs who want compact air cooling with a quiet fan rather than a larger dual-tower cooler; testing found solid cooling for its slim 120 mm class.

Real-World Use Scenarios

For a quiet home or office PC used for browsing, video calls, and everyday apps, the Dark Rock Slim is designed to keep CPU cooling unobtrusive during typical use.
For a gaming PC with a mainstream, stock-speed CPU, it offers a compact air-cooling option that reviewers found quiet under load; results depend on the CPU, case airflow, and fan settings.
When building in a case or motherboard layout where a larger tower cooler may be awkward, its slim design can simplify fit around memory; check the case’s CPU-cooler height limit before buying.
For light photo or video work and other moderate CPU tasks on a mainstream processor, it can provide quiet air cooling without taking up the space of a larger tower; intensive workloads may push it beyond its comfortable range.
For long rendering sessions or heavy overclocking on a high-power CPU, expect less cooling headroom than with a larger cooler; reviewers found it was not suited to demanding overclocked HEDT workloads.
