JUST 21.4dB(A) AT 100% FAN SPEED

The be quiet! Dark Rock 4 utilises a Silent Wings 135mm PWM fan to push air through the heatsink. Featuring a fluid-dynamic bearing for reliability, six-pole motor for reduced vibration, and nine fan blades for optimised airflow, the heatsink also uses a decoupled fan mounting and vibration-isolating elements to reduce noise even further.


A Single Tower

Excellent cooler, works perfectly. Compared to stock AMD A4 Wraith Stealth cooler that came with the 5600X, temps are generally ~10 degrees cooler with the Dark Rock 4. One thing to note though, if all 4 of your RAM slots are full, it will be a bit of a tight squeeze to fit the fan on the front of the heatsink; I had to fit it to the rear of the heatsink to pull air through, as it wouldn't fit due to me using all 4 RAM slots on my motherboard. Other than that, excellent cooler.

August 2020

Cools my r7 3700 under 70 with my all core overclock to 4.7 so I'm happy with my purchase. Was my first aftermarket cooler and installation is easy peasy


July 2020

Very good german quality, easy installation and really good performance. I use it with Ryzen 2600x and this cooler managed to bring temps by easily 20 deg under load and never throttles, very good product!


April 2020

Cooler performs amazing and very quiet. The installation was super easy, very high quality tools and comes with everything you need, even a BeQuiet! branded screwdriver.


February 2020

Great silent fan


December 2019

Got it at 10% off which makes it even more of a bargain. Solid quality product. A little tricky to get the fan hooks on but once on no issues. Keeps the CPU cool and with v little noise. Also has the option to add another fan if the CPU is over clocked.

Mr Lister sir!

computer very quiet now even with an over clock and gaming, great fitting to motherboard very secure, had a budget gammax before you get what you pay for, very happy with it.

Great cooler

Mr Richard Scott

March 2019

Used to cool an i7 8700k which was running 80oC+ under load with stock cooler. With the bequiet fitted my cpu temps dropped to room temp at idle and 40-50oC while under load. Cant recommend enough if you need to cool.


October 2018

Excellent cooler, I have an R5 1600 with an overclock @3.9ghz running @ 1.38 v, keeps temps cool at around 62c under stress test and also very quiet. Highly recommended.
