The ultra quiet AK-CCE-7104EP uses a high engineering omni directional heatsink providing efficient CPU and motherboard zone cooling. The enter bearing fan uses Intel approved power management (PWM) where speed is regulated automatically by CPU usage. Under normal conditions the CPU fan speed is low ensuring low noise computing. Intel approved pushpins ensure easy installation, reliable retention; pushpins will automatically slide into correct position. AK-CCE-7104EP is designed to work with CPU's up to 95 W but greater cooling efficiency can be attained with efficient case airflow. Pre-applied high performance thermal compound ensures clean and easy installation.
