Ultra compact and low noise cooler for Intel Core 2 Duo, Core i3 and Core i5 (73W) CPUs. The low profile design with embedded S-Flow fan makes it a perfect solution for mini-ITX, HTPC and SFF systems. Aluminium heatsink with full height copper core and quiet HDB bearing fan ensure high efficiency and long life. High engineered multi directional aluminium heatsink maximizes heat dissipation and PWM fan provides optimal CPU, motherboard and VRM cooling with minimal noise levels. Intel approved pushpins ensure easy installation, reliable retention and maximum compatibility on both LGA775 and LGA115X platforms without any mounting adjustment, pushpins will automatically slide into correct position. K25 is designed to work with CPUs up to 73W but greater cooling efficiency can be attained with efficient case airflow. Pre-applied high performance thermal compound ensures clean and easy installation. For Intel LGA775, LGA1150, LGA1155, LGA1156 Embedded 8cm PWM fan with S-Flow blades and long life bearing Intel approved push pins provide maximum compatibility. High performance thermal interface is pre-applied.
