ENZOTECH MST-81 heatsink was designed to offer exceptional heat dissipation for integrated MOSFET motherboards cards. MST-81 heatsink is made using a forged copper process which produces a dense material that is extremely efficient at heat extraction. The MST-81 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..
