be quiet! Pure Rock Review
be quiet! Pure Rock Review
Today we are going to have a look at an air cooler from be quiet! . To be more specific, it’s the Pure Rock, which has been released in 2014, and so already quite a long time on the market.
The packaging is typically black, as we know, it’s the marketing color of be quiet! The front side shows the cooler itself with maximal performance 150W TDP, and the backside covers all important technical specifications, as dimensions, weight, materials and socket compatibility.
Right after unboxing, the shiny surface of brushed aluminium will instantly get your attention. The packaging protects the cooler very well, and so your should arrive without any damages during transportation. All the accessories and screws are packed in a small cardboard box.
The build quality is at a high level, with a sense for every detail. Thank to four ø6mm heatpipes, the heat can be dissipated quite effective through aluminium fins of cooling tower. The cooler has already its thermal paste pre-applied by manufacturer. Its compact dimensions 87.5 x 121 x 155 (LxBxH) allow users to mount it into most cases on the market.
Nine blade silence-optimized 120mm be quiet! PWM fan with quality sleeve bearing is optimized for quiet operation. Its balanced between performance and noise, to produce optimal cooling with acceptable noise level. Nine air-flow optimized fan blades have reduced air turbulence due to special fan blade design. Thus, the fan stays very quiet at 26,8dB(A).
be quiet! Pure Rock is compatible with all current Intel and AMD Sockel (LGA775/115x/1366/LGA2011(-3) and AM2(+)/AM3(+)/FM1/FM2(+)
The mounting procedure is pretty simple and quick. The included fan can be mounted on both sided depending on your own system setup or preference. Should you wish to use higher RAM modules, you can quickly adjust the fan in higher position as well.
To ensure that the results from one review to another are comparable, the Testing Methodology will be the same throughout all reviews, otherwise we will make a note if somethings changed and keep it separately from other results.
All testing was done on test Bench-table with a room ambient temperature of 22- 23°C and if temperature changes we will add delta T °C to the results.
Before testing we run 10 minutes of Prime95 followed by 30 minutes of idling. This warm up period was done at stock CPU core frequency. For noise testing we are using fanless PSU. We mostly do fan noise test over night so we have our room as silent as possible.
Testing system :
For testing we used OCCT software and between each test we left the PC at least 15 minutes to rest so that the temperature went back to the IDLE state. Followed by overclocking. Each test lasted for 15 minutes. If the temperature of any CPU core exceeded 85°C the test was automatically turned off and the value of the results was marked as “failed”. The temperatures in the tables are the average temperature of all cores. The results of the tests are influenced by many factors such as the amount of thermal paste, pressure between the processor and CPU block, humidity, thermal conductivity of thermal paste, etc.. Therefore, this results should be considered as indicative only.
For this test we use its own thermal paste provided by manufacturer.
Intel® Core™ i7-4790K Processor
Stock Load PWM: 990RPM
OC Load: 1500RPM

With Pure Rock, be quiet! had to make some compromises between performance and price, and they did achieve their goal actually. Thanks to its compact design, it should fit into most systems. Interesting is its performance in overclocked system. As it’s still capable of cooling our overclocked system. All in all a nice price/performance product for €29 which has earned our Silver Recommendation award.
not suitable for high overclocked systems
not 100% compatible to high RAM modules
