DeepCool AM5 Thermal Paste Guard The AM5 Thermal Paste Guard is a multi-aspect solution for AMD's AM5 processor line. The copper frame will greatly improve thermal transfer, increase structural stability, and help keep thermal paste out of the cut-outs in the heat spreader. Keep It Clean Cut to match the shape of the AM5 heat spreader, the thermal paste guard protects against the accumulation of thermal compound in the crevices of the AM5 CPU. Keep It Cool The copper frame of the AM5 Thermal Paste Guard greatly improves heat transfer by increasing the surface area between the processor and cooler. Set It And Forget It Designed to remain in place through countless CPU cooler installations on an AM5 processor, the guard is a true "set it and forget it" solution.
