Is it OK If I didn't remove the Dan's for deep cleaning of my PS5

So I have had my console for 3 years now. I do sometimes pop off the lids and clean them properly from both sides but taking off the fan really scares me and I would really prefer not doing it. Even though I do see dust build up inside it but I'm just too afraid to try to take it off so is it okey if I just let it be?
