The Thermalright Silver Arrow SB-E is a massive CPU cooler that covers most new platforms. Its massive size starts with 8 x 6mm sintered heat-pipes that are nickel plated for slower oxidation ensuring a long lasting cooler. Next the fin area is an astounding 154mm x 120mm in surface heat dissipation area with 120mm & 140mm fan compatibility. Finally this cooler comes stock with dual low noise PWM fans to keep your temperatures to the lowest possible. (1 x TYR-150 & 1 x TYR-141) A third fan can be mounted to this cooler due to its unique twin high rise design. 8 X 6mm sintered heat-pipes effectively takes away excessive heat from the CPU when overclocked, Nickel Plated heat-pipes, slower Oxidation & deterioration of the heat-pipes, provides longer period of Thermal conductivity. Double fin design, each side with 154mm*120mm heat dissipation area, can be used with 14 or 15 cm fan (fan clips included). Special Arrow fin design, which allows cool air to pass through & take heat away rapidly, effectively provide cooling for the cpu. Support Multiple-Platforms. Can be used on Socket 2011/1366/1155/1156/775 Platform, & AM2/AM2+/AM3/AM3+/FM1 Sockets. Including TY-150&TY-141 Ultra low noise PWM fans & PWM Y-Cable. With the compatibility of up to 3 fans maximum.
