The Choten uses a top-flow design to actively cool all surrounding mainboard components through the airflow directed from above. This has a positive effect on system stability and service life. During the development of the Choten, the focus was not only on excellent performance, but also on unrestricted compatibility with RAM. The asymmetric design, coupled with a large gap between motherboard and heatsink, ensures excellent compatibility with large memory modules. With a preinstalled Kaze Flex 120 PWM fan, the total height of the Choten CPU Cooler is only 122 millimeters, allowing it to fit into all popular PC cases. This mix of good features, high compatibility, and a high-quality fan makes the Choten CPU Cooler a well-rounded solution for compact systems.


E.C.M.S. II (Easy Clip Mounting System II)

The Choten CPU Cooler is equipped with the E.C.M.S II (Easy Clip Mounting System II) mounting system, which supports AMD’s newest AM4 socket as well as a variety of other Intel and AMD sockets. The second generation of the E.C.M.S is designed for ease of use and quick installation. To achieve this, the assembly system consists of only two parts, each of which can be assembled with a few simple steps.

Kaze Flex 120 PWM Fan

The Choten T CPU Cooler is equipped with a PWM fan from the award-wining Kaze Flex series, operating in a range from 300 to 1200 RPM. The self-contained liquid bearing (Sealed Precision FDB) reduces friction and wear to a minimum, resulting in an average lifespan of 120 000 hours. Rubber pads mounted in the fan frame have a decoupling effect and prevent the transfer of vibrations.

Asymmetric design and low height

The Choten CPU Cooler features a top flow design with the advantage of providing active cooling to the CPU power delivery components on the motherboard. The radiator is offset to improve the RAM compatibility while also maintaining a balanced shape for the cooler. In addition, the cooler has a height of only 122 mm with the fan installed, thus being compatible with a wide range of PC chassis.
