Noctua Thermal paste guard and cleaning set

The NA-TPG1 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, the NA-TPG1 prevents this undesired phenomenon. Combined with the ten included NA-CW1 cleaning wipes, the NA-STPG1 set gives you everything you need to keep your AM5 processor clean.
