The 4646-06C01 is a simple yet highly effective means to preclude thermal paste build-up in the cut-outs of the heatspreader of AMD AM5 CPUs. When the mounting pressure of the cooling solution is applied, excess thermal paste will be squeezed outwards. With AM5 CPUs, this excess paste tends to accumulate in the cut-outs at the sides of the heatspreader and may become difficult to remove. Simple and risk-free to apply, it prevents this undesired phenomenon.
