Two heatpipes & aluminum fins are designed for maximum cooling while switching noise free, down-blowing 110 mm fan minimizes noise & cools not only the CPU but also provides powerful peripheral cooling. DTH technology transfers the CPU's heat directly to heatpipes, thereby minimizing heat resistance & maximizing cooling performance. Compatible with Intel LGA1366/1155/1156/775 & AMD FM1/AM3+/AM3/AM2+/AM2
