Introduction, Specifications and Pricing


While be quiet! is not new to the CPU cooling game, the idea and basis for their latest cooler to hit the labs is. Where most of the be quiet! coolers will offer great thermal results and will do so with very little noise coming from the fans, most of their better coolers cost in excess of $80. While enthusiasts have no issue forking out the higher pricing that some coolers demand, be quiet! was missing out on a huge market segment, the more economically friendly segment for system builders and beginners into mainstream users. With what we have seen in the past, we feel that this should not be much of a challenge for be quiet! to accomplish; the real question is what sort of performance we are going to get.

This is a standard tower design that on paper should be more than capable of handling the demands of most users out there looking for aftermarket CPU coolers. At the same time, the idea was to make the cooler as compact as possible, yet still offer ways to make the airflow more effective with less materials to work with. This design is also fully compatible with all current Intel and AMD sockets, so that anyone from the low-end-user to the people looking for a tower cooler to stay silent in an HTPC, this design covers the gamut of needs in a CPU cooler, and still presents it in a very attractive aesthetic not always seen on lower priced coolers.

We already are well aware of the Dark Rock coolers and the Shadow Rock series, but this is the one and only Pure Rock, the latest addition to the be quiet! cooler lineup. Now there are a couple of minor details about this cooler that in our opinion take away from what we know as a be quiet! cooler in the past, but as you will soon see and likely agree to, for what you have to invest to obtain this level of cooling and silence while doing so, any gripe you may have had is easily wiped away, because the Pure Rock cooler still packs quite the feature set for something priced this low.

be quiet! Pure Rock CPU Cooler Review 01 |

be quiet! is always very in depth in the amount of information they provide their potential customers when it comes to the specifications of their products. Case and point, the chart provided for the Pure Rock offers more information than we could show. This aluminum and copper cooler stands 155mm in height, it is only 121mm wide, and is 87.5mm deep with the fan on the tower. While we see the 660 grams of weight listed, we then see a TDP rating of 150W listed, while the box showed us 130W. Next we run into the socket compatibility, and at a quick glance, all relative sockets are covered, even some legacy sockets. For now, skipping over the fan details, we then see the finer details of the towers composition. We find here that the base is CNC machined, and that there are four 6mm diameter heat pipes used in this design.

Back to those fan specifications. Along with the tower is a 120mm silence-optimized fan, and we are immediately given its noise ratings at various speeds, topping out at 26.8 dBA. Jumping back down the chart a bit, we see that this fan has a maximum speed of 1500 RPM delivering 83 CFM through the tower, with 1.25 mmH2O of static pressure to back that flow. This fan is powered via a 4-pin PWM connection, and is also rated to run for 80,000 hours. Oh; if you were wondering, there is a warranty as well that will cover this cooler for the period of three years.

The thing is, that even with a compact design, being cooled with a 120mm fan, and that it is indeed very universal to both the sockets and its usage, the fact that it can be had for less than $35 makes the deal that much sweeter. Of course, you could opt to buy from where the Pure Rock is listed at $53.55, or you can shop around a tad. This lead us to look at, where currently we find the Pure Rock sitting there ready to be nabbed for just $34.90, and it comes to the door free of charge. So right from the word go, we know what the cooler is made to do, we know what it costs, so let's get right to it and see exactly what it is you get for this minimal investment.

After a year of gaming, Chad caught the OC bug. With overclocking comes the need for better cooling, and Chad has had many air and water setups. With a few years of abusing computer parts, he decided to take his chances and try to get a review job. As an avid overclocker, Chad is always looking for the next leg up in RAM, cooling, as well as peripherals.
