What are the rubber circles for on the back of my pc case? Should I just leave them like that if don't have a need for them? Or are they likely to let I'm dust into the motherboard?
Edit: thanks for all the replies, so just for water cooling I have no need for.
They are external ports for water cooling. They allow you to run the pipes to an exterior location, and I have never seen anyone use them ever. I would leave the rubber grommet as it generally looks nicer than the hole.
Built a computer for a guy years ago. Dual titan X, 3 radiators in a little fucking HAF tower. He bought two exterior radiator mounts
Was about to ask what one does with dual Titan Xs, but the obvious answer is whatever the hell one wants.
Yeah SLI was still a thing at the time. From what I gathered he was trying for XOC records on liquid. He only came to us because he didnโt want to spend the time building it
