Test – be quiet! Pure Rock : Specs | CPU | Hashrate | Review | Config

Hi everyone!

After the enormous Dark Rock 3 and its big brother the Dark Rock Pro 3 both placed in the top of the range be quiet! returns with this here is an entry-level model, the Pure Rock! A tower cooler with 4 heat pipes given to cool 130 Watts in silence offered at a price of 32.90 €, what does the first entry-level cooler from be quiet have in store? This is what we will see!

The box is in the spirit of be quiet !. Very sober with the profile photo of the product as well as the name of the model, the cooling capacity of 130 Watts as well as the maximum noise pollution (26.8 dB) and the compatibility with Intel and AMD processors.
At the back we find the technical characteristics of the Pure Wings, weight, dimensions, compatibility with different sockets, noise pollution, etc.

On the sides nothing special to report, the recommended applications are mostly multimedia systems and graphics applications, apparently it is not recommended to play with the Pure Wings! All in 6 languages, 3 on each side.

Once the box is open we fall on a piece of cardboard holding the cooler in place to prevent it from moving during transport, once the cardboard has been removed we can see the fan separated from the cooler by a piece of foam and the bundle box on the side. The packaging is not up to a high-end model here but is more than enough, no problems to deplore.

Here is the radiator, 48 aluminum fins crossed by 4 copper heat pipes 6mm thick, the finish is correct without being excellent, some fins were a little twisted at the ends and they are not perfectly parallel, but nothing that could harm the performance. Let’s not forget that this is an entry-level product 🙂

On the top we find a rather nice aluminum plate which gives a little more upscale side to the whole, the ends of the heat pipes are covered with aluminum caps of the most beautiful effect as well.

be quiet! has this time chosen to pre-apply thermal paste, certainly less expensive than putting a separate tube in the box, let’s remove it all to see the surface!

The surface does not quite benefit from a mirror finish but remains very well made, we are far from a low-end finish here.

The ventilation is entrusted to a Pure Wings 2 of 12cm PWM rotating at a maximum of 1500RPM and given for a sound level of 26.8 dB. It should be pretty unobtrusive even at full load, but we’ll see that later!

The fan is fixed using 2 clips provided for this purpose, no problem to report during assembly.

The be quiet! Bundle Pure Rock consists of:

• 1 radiateur Pure Rock
• 1 ventilateur Pure Wings 2 12cm PWM
• 1 kit de fixation Intel
• 1 kit de fixation AMD
• 2 fasteners for the fan
• 2 installation sheets

As we can see the bundle of the be quiet! Pure Rock offers everything you need to install it, no additional accessories, only the main one!

As usual at be quiet! Pure Rock is compatible with almost all sockets on the market, ranging from LGA 775 to 2011-3 at Intel and from Socket 754 to FM2 + at AMD, which means that it will be possible to install it in 99% of configurations, a very good point! In terms of dimensions and weight, the cooler is very classic with 660g and a height not exceeding 15.5cm, the compatibility with the boxes will therefore be very wide.
The Pure Wings 2 PWM fan rotating at a speed of 1500 RPM maximum for a noise nuisance of 26.8 dB should be in the spirit of the brand namely silent.
The 3-year warranty as well as the recommended price of 32.90 € TTC should make this Pure Rock a very good alternative to the Cooler Master Hyper 212 Evo, if the tests are conclusive. Now that all is said, it’s time for editing!

After the Dark Rock 3 and Dark Rock Pro 3 fixing system which turns out to be rather laborious be quiet! decided to switch to the little Pure Wings and move to a more classic and easier to install system, let’s see that!

First of all you have to take the plate that is placed at the back of the motherboard and find the right notches for the socket used, for my part the 1156 socket (same as the 1150 and 1155) so those in the middle.

All you have to do is place the screws provided for this purpose and add a rubber washer over it so that everything does not move, do this in the 4 corners of the plate.

Once the 4 screws are in place, simply place the motherboard on top, as in the photo above.

Once placed, the plate must be screwed using the 4 nuts provided for this purpose.

We’re almost done! You must place the 2 plates as in the photo above.

To finish it is enough to place the radiator on the processor, to place the central bar and to screw it to the 2 plates, and here is the be quiet! Pure Rock is in place!

The test platform

The be quiet! Pure Rock has been tested on the configurations below:

• Processor: Intel Core i7 875K @ 3,2 Ghz
• Motherboard: Asus P7P55D
• Memory: Kingston HyperX 4 x 2 Go 1600Mhz
• Hard disk: WD Raptor 150 Go
• Graphic card: Sapphire Toxic 5850
• Food: Seasonic X650

The test protocol

The core i7 875K has been slightly overclocked to 3.2Ghz. The temperatures under load are an average of all the cores for 3 tests of 30 minutes on OCCT, the temperatures at rest were taken after 15mins on the desk (still an average of the 4 cores).

The cooler has been tested against:

• be quiet! Dark Rock 3 (tested here)
• be quiet! Dark Rock Pro 3 (tested here)
• Noctua NH-U14S (tested here)
• Noctua NH-U12S (tested here)
• Scythe Mugen 4 PCGH (tested here)
• Noctua NH-D15 (tested here)
• Thermalright HR01 + 1 Nexus real silent 120 fan (tested here)

The temperatures

The cooling performance of be quiet! Pure Rock are very good for a cooler of this range, in fact with 61 ° maximum in 5V the processor is very well cooled and certainly does not reach the dangerous zone, in 12V and with 54 ° maximum it does not deserve either more. The PWM mode brings the processor to a temperature of 56 °, it will be necessary to see the associated noise pollution to draw conclusions.

Noise pollution

Attention : Part to be taken with a grain of salt, unfortunately not having access to the appropriate equipment and using an android application to take the readings the measurements below are only indicative! The readings were taken 15cm from the cooler.

Powered by 5V, the fan is quite simply inaudible compared to the ambient sound level of the room and the be quiet! Pure Rock is therefore excellent. Once supplied with 12V there the fan is clearly heard but while remaining pleasant to the ear, by this mean that there are no parasitic noises coming from the engine or others, only a noise of air flow is present. The happy medium is therefore found in PWM mode (managed by the motherboard) with 38dB which is really very good and will generally be forgotten compared to the noise of the other components of the configuration, in particular the graphics card.

Here we are at the end of this test, what can we say about the brand new be quiet! Pure Rock?
be quiet! has decided to launch into the entry-level cooler market, and it must be said that this trial run is rather successful! The performances are quite acceptable, whether in 5V or in 12V, without arriving of course at the level of the tenors of the air cooling but it is able to keep a processor cool as long as it is not too overclocked. . In terms of noise pollution it is also very good as long as the fan is not pushed to the maximum, in 5V or in PWM it will be very discreet. The build quality is pretty good without of course reaching the level of high-end models.
Offered at € 32.90 incl. Tax the be quiet! Pure Rock is an excellent alternative to the Cooler Master Hyper 212 Evo and will be perfect to replace an original cooler for more silence and / or a small overclock in a gaming pc.

Many thanks to Armelle from be quiet! which allowed me to do this test.
