Based on the highly praised Kaze Flex PWM fans, which are bundled with the award-winning Mugen 5 CPU cooler, a complete series with three models with different speed options is now available.

The sealed fluid dynamic bearing (Sealed Precision FDB) ensures an average life-span of more than 120.000 hours.

Decouplers attached to the fan frame reduce the transmission of vibrations and thus contribute to a very low noise level.
