I’ve finished my custom water cooling build for about a month. Today, it suddenly came to me that I might have forgotten to add thermal paste on my CPU... I am using a ryzen 9 3900x, and it averages 45 degrees idle. The high temps have perplexed me for a while, and not having applied thermal paste would have explained them perfectly... The thing is... there is still a chance that I have applied the thermal paste, as it has been a few weeks, and I have no recollection whatsoever... I don’t want to risk taking my whole loop down just to discover that thermal paste has been there the whole time... what should I do?
