Phanteks Ultra Low Profile CPU Cooler with 3x6 mm Embedded Copper Heat-Pipes and PH-F90PWM Premium Fan PH-TC90LS Phanteks patented P.A.T.S (Physical Antioxidant Thermal Shield) technology dramatically increases the cooling performance and reliability of PH-TC90LS by deflecting thermal radiation from other heat sources, like GPU, South Bridge, North Bridge, and etc. Phanteks patented C.P.S.C Technology is a new innovative forming deposit tht transfers heat onto corresponding metals at a more rapidly rate. PH-TC90LS enhances thermal conductivity on the soldered surfaces of the heat-pipes thru the copper deposits. The PH-TC90LS is made to ensure it has the least amount of air and thermal resistance. To prevent mechanical conflicts with other components, PH-TC90LS follow Intel's Keep-Out-Zone (95x95mm) requirements. Phanteks PH-F90 PWM Premium fans uses UFB (Updraft Floating Balance) bearing, Nine blades and MAFO (Maelstrom Air-Fort Optimization) drive system to achieve massive airflow and perfect dynamic balance. PH-TC90LS takes less than 1 minute to install. It requires 4 screws and the rotational back plate for the Intel LGA 2011/1155/1156 to tightly secure it to MB.
