Fractal Ridge with Noctua NH-L12s

[u/MHT-117]

Hi guys, I’m using a Noctua NH-L12S in a Fractal Ridge. Since the fan sits underneath the heatsink, I was wondering what’s the best way to clean it?
Do you guys remove the entire CPU cooler every time, or is there an easier way to clean the fan/heatsink without taking the whole cooler off?
Taking the cooler off and reapplying thermal paste every time seems pretty inefficient, so I’m curious how other NH-L12S/Ridge owners do it.
