This is my first time building a PC with a water cooling system. After a month of work, I noticed oil smudges on the fans. It probably shouldn't be like that. Down does not flow, but I'm afraid that it may get worse. In my opinion, it’s better not to save on such a thing and take either reliable air cooling or a more expensive dropsy.
As promised, I have included some photos to give a visual of my experience.
