Deepcool Z5 CPU Thermal Compound (DP-TIM-Z5-2) is perfect for almost all CPU cooling applications thanks to its high thermal conductivity. Its been designed to fill in the microscopic peaks and troughs in the surfaces of the CPU heatspreader, and the heatsink surface to ensure maximum cooling potential. It's density is compatible with polished CPU coolers, and isn't conductive so it helps prevent electrical damage!
