The silent heat killer returns with its aesthetics and maximum cooling performance. The Assassin IV offers exceptional performance and is equipped with seven heat pipes as well as 120mm and 140mm FDB fans. The latest addition to the Assassin series claims the crown of air cooling, both in terms of cooling performance and ultra-quiet operation. The elegant design of the Assassin IV is not only visually appealing, but also leads to optimal airflow and maximum compatibility. By simply flipping a switch, the Assassin IV can transform from a whisper-quiet cooler, when low noise is of utmost importance, into an unrestricted cooling powerhouse when peak performance is required. The chassis of the Assassin IV is sleek and slim, helping to direct airflow through the fin towers, while the offset 120mm fan provides ample space for high-end RGB memory.
