Arctic Cooling fits the stereotype of a European engineering company very well. For the most part, their products are smart implementations of elegantly simple ideas, such as their Super Silent series of heatsinks or their VGA Silencer. Unlike most famous European brands, Arctic Cooling doesn't go after the high end market. Most of their products are modestly priced, and, even if they're not the top performers in their class, tend to be very good value. In this respect they're a bit like IKEA: Cheap but usually nice and a bit quirky.

The Freezer series served as their "high end" model, the low ~US$35 price notwithstanding. Even though it was Arctic Cooling's best CPU cooler, it was no match for the latest and greatest from Scythe, Thermalright and Zalman, which may be why Arctic Cooling released a new version called the Freezer Pro. It features a larger fins, an extra heatpipe, and a different, soft-mounted fan. The soft-mounted fan is especially interesting because it shows how seriously Arctic Cooling considers noise in their design process ? not just their marketing materials.


The package is small and mostly monochromatic. Classy.

The Freezer Pro comes in two variants: The Freezer 7 Pro and the Freezer 64 Pro. The main difference between the two is the mounting system. The Freezer 7 Pro is compatible with Socket 775 processors (Intel), and the Freezer 64 Pro with Socket 754/939/940 processors (AMD). According to Arctic Cooling's datasheet, the two models also feature slightly different fans. This makes sense, since most Intel processors produce more heat ? and thus require more airflow ? than AMD's models. Our sample is a Freezer 7 Pro, which comes with a 4-pin fan that is a little faster than the 3-pin fan that ships with the Freezer 64 Pro. No samples of the Freezer 64 were available in early November.


A fitted plastic casing protects the Freezer 7 Pro in transit.
The only other things included in the box are an instruction sheet and a small, branded sticker.

Arctic Cooling Freezer 7 Pro: Feature Highlights (from the product web page)
Feature & Brief Our Comment
Extremely Quiet: The low speed 92 mm fan reduces the noise level to a minimum. The patented fan holder is able to practically eliminate the typical buzzing sound of 92 mm fans.
Other Arctic Cooling products have been fairly quiet, so we have hopes that this one will be as well.
Powerful Cooling: 6 Heat Pipes (three used double sided) are able to transfer heat up to 200 Watt. The heat exchanger is built of 42 fins and consists of a surface area of over 4700 cm2 and allows for resistance free energy transfer to air.
This is Arctic Cooling's high end model, so they want to take on the best...
Integrated Cooling of Voltage Converters:
Air is drawn in from the side of the fan to cool the components around the CPU. Some air is blown out towards the voltage converters on the mainboard with the bent fins at the bottom.
An important feature for any tower style heatsink, since the direction of the fan means that the motherboard doesn't get as much cooling.
Patented Vibration Absorption: The four rubber connectors on the fan case act as a vibration damper to absorb the vibration of the running fan and prevent vibration transfer to the heatsink and the case.
An unusual noise-reduction feature that makes a difference at low fan speeds.
Easy Installation: The cooler is to install without any tools within seconds.
Uses Intel's stock mounting mechanism.
Long Lifetime / 6 Years Warranty: The ARCTIC Ceramic Bearing provides an unmatched Life Time of 137'000h (L10@40°C) resp. an MTBF@70°C of 163'000h and thus a 6 year warranty.
Six years is a long time. Just think, that's about nine development cycles for Intel...
