I have a 6700k and a noctua d15s, I have reapplied my thermal paste about 20 times now and tried gelid gc extreme, mx4, and nth1, right after i apply my thermal paste temps are around 72 on all cores on max load, but after 1 day of normal activity the temperatures become ~72-80-72-80 on my cores, i know cores being different temperatures is normal but i don't understand why its consistent after i apply new paste but not 1 day after, i have reapplied different pastes 20 times and the result is exactly the same.
