The Gelid “Rev. 2 Silent Spirit” heatsink features 4 sintered power heatpipes with Direct Touch Technology. The flattened copper heatpipes with direct contact to the CPU surface ensure maximum heat transfer from CPU to the aluminum fins. The heatsink is built in a unique shape and aligned at a specific angle to provide best air flow to a maximum surface. Therefore the Northbridge (chipset) heatsink and the voltage regulator modules located close to the CPU can be cooled as well. This Top-flow cooler “Rev. 2 Silent Spirit” is designed based on an open frame structure concept to provide as much air flow as possible. As its predecessor software calculations were made during the development in order to improve the cooling performance and reduce noise. The heatsink is bundled with a silent 92mm fan with high airflow. The fan comes with an intelligent PWM control which allows users to set the fan speed in their BIOS accordingly. Further high quality antivibration fan mounts are included to keep the fan stable while running. The cooler is compatible to Intel™ 775/ 1155/ 1156 and AMD™ 754/ 939/ 940/ AM2/ AM2+/ AM3/ AM3+/ FM1 sockets, is RoHS and WEEE conform and has warranty of 5 years.
