✗ Slim fin stack trades raw surface area for clearance

Manufacturer description

The be quiet! Pure Rock Slim 3 is built for the builds everyone else's coolers won't fit into. Its slim-tower, asymmetric heatsink clears tall RAM and the first PCIe slot, so you can drop 130 W of cooling capacity into a mini-tower or a cramped mATX case without a fight. Three nickel-plated heat pipes pull heat off the CPU and spread it through the fin stack, where a 100 mm PWM be quiet! fan handles it at speeds that stay in the background rather than in your ears. Mounting is deliberately low-drama: dedicated AMD and Intel frames, minimal hardware, and support for LGA 1851 (Default ILM) and…

Frequently Asked Questions

Will the Pure Rock Slim 3 fit in a small case?

Is 130 W enough for my CPU?

How hard is it to install?

Does it come with a fan, or do I buy one separately?
