Passive Intel CPU Cooler The Alpine 12 Passive comes without a fan and yet provides enough power to keep all compatible Intel CPUs up to 47 Watts at bay. It offers an affordable solution for fully fan-less computers on Intels 115X Sockets. Black Anodising for Improved Heat-dissipation The micro-porosity resulting from the heatsink surface treament optimises the heat exchange between the aluminium and the surrounding air, thus the cooling performance in passive mode is greatly improved. Pre-applied MX-2 Thermal Paste Thanks to the pre-applied MX-2 thermal compound, a quick and clean installation is guaranteed Dust and Maintenance Free No fan means no dust and no maintenance over time. Easy Installation & Optimal Compatibility Fast and easy to install and extremely reliable, the Alpine 12 Passive mounting system is compatible with the Intels 115X sockets. It is not only fool-proof to install, but also absolutely transport safe.
