Be Quiet! Dark Rock Pro 2


Testing and Overclocking

Test Rig

  • CPU: Intel 3770K – Stock turbo – all cores enabled – HT enabled
  • GPU:  Zotac GTX680
  • Memory: 16GB Corsair Vengeance 1600MHz 9-9-9-24 DDR3
  • Storage: Crucial C300 128GB
  • PSU: SuperFlower Golden King 550W Platinum
  • OS: Windows 8 Professional x64
  • Case: Coolmaster Cosmos 2


To ensure the results were consistent, the heatsink was mounted three times and idle and load tests run each time. An average of the results is shown below.

For idle testing, Windows 8 was allowed to run with no programs for 10 minutes.

For load testing we use Prime 95 Small FFTs and temperatures were taken after 20 minutes.

The standard thermal paste, provided with the cooler, was used.


The settings we used for our stock and overclocked tests are:

Stock – 3500MHz – Turbo 3900GHz

Overclocked – CPU 4400MHz 1.275v



The Dark Rock Pro 2 demolished all other competitors by a 4C margin at load while being the quietest of the bunch, this thing is a pure beast!


The Dark Rock Pro 2 reaches 2nd place, behind the Supreme HF but it’s hardly fair to even compare the two considering how much more a full water loop costs. Compared to the other air coolers, this thing is pure awesome, the fans didn’t even start to spin up until I really started to push the clock and voltage upto 4.9GHz and 1.375V, this thing is extremely impressive.


The Dark Rock Pro 2 is the first Be Quiet product I’ve reviewed and I am amazed at the entire package.

The build quality is the best I have come across to this date, not only is the Dark Rock 2 built extremely well, it’s extremely well thought out too.

Installation is easy and other than the little plastic clips that only hold the screws in place while you mount the cooler, the whole mounting system is made of metal and thick metal too, the provided back plate feels like it could survive a bomb blast.

At £62 the Dark Rock Pro 2 certainly isn’t the cheapest cooler on the market but for those who want to get serious and get one of the very best coolers on the market, the Be Quiet Dark Rock Pro 2 is the way to go.


  • One of the easiest coolers I have ever installed
  • The best performing air cooler I have tested
  • Very quiet, the quietest I’ve tested



  • You pay a premium price for a premium product
