ENZOTECH MST-780i heatsink was designed to offer exceptional heat dissipation for integrated MOSFET motherboards cards. MST-780i heatsink is made using a forged copper process which produces a dense material that is extremely efficient at heat extraction. The MST-780i heatsink is far superior to traditional heat sinks currently found on the market and it provides the best thermal conductivity available to dissipate heat from the MOSFET in your system..
