Arctic Freezer 33 HSFs get Ryzen support

Posted on Wednesday, Mar 08 2017 @ 13:02 CET by Thomas De Maesschalck
Arctic Cooling announced it updated its line of Freezer 33 processor coolers with AMD Ryzen (Socket AM4) support. These tower heatsinks feature four 6mm direct-touch heatpipes and consist of 49 aluminium fins. Airflow is provided a a 120mm PWM fan with fluid dynamic bearing, it is rated at a noise level of 0.3 Sone.

The basic Freezer 33 has one fan, while the Freezer 33 Plus has two fans in a push-pull configuration. Furthermore, Arctic also offers the Freezer 33 CO, this model is rated for continuous operation. The Freezer 33 and Freezer 33 Plus are now available via the company's webshop and Amazon for 45.99EUR and 49.99EUR, respectively. The Freezer 33 CO will follow next month for 49.99EUR.

Arctic gets Ryzen support
ARCTIC announces its new Freezer 33 Series. The high-performance semi passive CPU coolers Freezer 33, Freezer 33 CO and Freezer 33 Plus are the successor models of the Freezer 32 series. They are equipped with PWM controlled 120 mm cooling fans and offset heat pipes to ensure optimal heat dissipation. The low footprint of the Freezer 33 avoids interference with the RAM, even if there are two fans used. Fast and easy to install and extremely reliable, the mounting system is compatible with Intel and the new AMD Ryzen AM4 socket.

Semi passive cooling makes the Freezer 33 coolers very efficient and extra quiet. During simple applications, such as creating documents, the CPU is cooled passively. The F12 PWM fan only powers up at a higher load, starting at 40 % PWM. In this way, an optimal cooling capacity at a low noise level is guaranteed.

The Freezer 33 Plus features an additional F12 PWM cooling fan mounted on the opposite side of the radiator providing a great airflow and increasing cooling capacity significantly. Both the Freezer 33 and the Freezer 33 Plus are equipped with a durable high precision bearing, reducing friction and achieving a greater efficiency and less heat development.

The Freezer 33 CO is specifically designed for continuous operation. The Japanese dual ball bearing, used in the "CO" version, reduces rotational friction considerably, is significantly less sensitive to dust and high temperature and hence up to 5 times more durable than other bearings.
