I have a noctura nhd14 cpu cooler that is 9 years old. It has 2 large heat sinks and 2 fans. My amd rysen 7 5800x idles at 50 C. My AMD OC app was limiting the processor speed to 4.2 GHz due to a max temp of 90C. The heat sinks were cool and the pipes to the heat sinks were cool. ambient temp is 21 C. I installed the cooler with a thin layer of evenly applied Artic mx4 thermal paste. Is this normal temps or is my cooler not operating properly?
