The core features that result in high-end cooling

The compact single-tower design achieves excellent heat dissipation in small spaces.  One fan is pre-installed. It is also possible to add another 120mm fan for even better cooling.

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

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!

Great silent fan

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.

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.
