Totally silent
Perfect for silently cooling my processor! The joy of hearing nothing :-)
Easy to install
The Dark Rock 4 from Be Quiet! is the new iteration of the German manufacturer's flagship fan. This new version offers more performance, easier assembly and a perfect silence thanks to the use of a 135mm SilentWings fan.
The Dark Rock 4 mounting kit is completely black to match the black ventirad with a beautiful brushed aluminium cover. The compact single tower design allows for excellent heat dissipation in your gaming case with the option to add a second 120mm fan to improve the already near perfect dissipation.
The Dark Rock 4 is equipped with six 6mm copper heatpipes for maximum thermal conductance. They are coupled with the fins to optimise the heat exchange surface and thus offer optimal heat dissipation. The Dark Rock in its latest version can handle a maximum TDP of 200W. All of this takes place in an appreciable silence as the 135mm SilentWings fan generates a maximum of 21.4 dBA.

Perfect for silently cooling my processor! The joy of hearing nothing :-)
Easy to install
The best ventirad I've ever used, with optimum efficiency even in ultra gaming! Of course it's a ventirad that makes a bit of noise at full power but honestly it's worth it!
The real drawback is its size, but you can't make an omelette without breaking eggs, forget about the 4 rams 3 strips, yes, but the dual is advantageous, I prefer 2 good strips in dual, which is more than enough!
This fan was needed to cool an i5 12600 KF: boosted to 4.7 Ghz, the temperature rarely exceeds 80 degrees.
satisfied :)
Received the product without any problem, easy to install with a screwdriver, we'll see if it lasts.
Very good ventirad from Be Quiet, equipped with 6 copper heatpipes and quite quiet for a very affordable price.
