The compact size 60mm fan is the ideal choice for small form factor applications. Moreover, with the built-in PWM fan and metallic blades and fins design, the Engine 27 guarantees extremely low noise level without compromising on the cooling performance. Low-Profile 27mm Height Designed with 27mm height, the Engine 27 is the ideal CPU cooling solution for slim and small form factor applications, such as 1U server, HTPC, AIO/PIO PC, POS terminal and Booksize/Mini PC. Unique Metallic (Alumium Alloy) Structure with Superb Heat Dissipation Unlike traditional CPU coolers, the Engine 27 features a metallic structure and copper base that provides more fortified and efficient thermal paths for CPU. The metallic fan is designed to directly pull heat from CPU. Especially, the metallic fan base is engineered with small radial gaps that allow heat to be transferred rapidly to the rotating metallic fan. Hence, when the metallic fan blades generate cooling airflow, heat will also be transferred to the flowing air by both rotating fan and stationary fan base at the same time.
