Enermax Twister CPU Air Cooler with 120mm LED Fan ETS-T40-BK Black UNIQUE TCC DESIGN - The ETS-T40-BK features a unique TCC (Thermal Conductive Coating) to improve thermal transference and prevent oxidation of the contact surface. THERMAL RESISTANCE PERFORMANCE OF 0.085 Degree C/W is achieved by 3 innovations: Stack Effect Flow to enhance heat transfer, Vortex Generator Flow to supercharge air convection. HEAT PIPE DIRECT TOUCH - The ETS-T40-BK features the side flow type with four 0.6mm high-performance heat pipes using HDT so the heat from CPU will be transferred directly to the heat pipes without additional resistance. 120MM PWM COOLING FAN - The ETS-T40-BK is available with dual fan option and its 12cm Twister Bearing PWM fan automatically adjusts the speed according to the requirements of the particular CPU platform. UNIVERSAL COMPATIBILITY - The ETS-T40-BK includes a universal bracket for Intel LGA775/1150/1155/1156/1366/2011 and AMD AM2/AM2+/AM3/AM3+/FM1/FM2. The bracket also supports Intel's latest 4th Generation processors. ANTI-VIBRATION RUBBERS AND HIGH THERMAL CONDUCTIVITY GREASE - Anti-vibration rubbers prevent fan vibration and absorb noise. High thermal conductivity grease ensures the best thermal conduction between CPU and the heat sink. One Black Twister LED PWM fan included
