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.
Mine has an 3 position exrernal fan switch for manual control, cable comes out those holes. Also useful for direct header usb that you run an extender cable out to another device.
3 position? all of my fans get controlled in software from 0-100% speed, reacting based on temperature
While that is an option for anyone, its not something I wanted. Mine is cube with 200mm fan. The lowest setting is fine for the thermals, but if I’m video processing I will toggle to high, but for voice over or a phone call comes in I drop it down low. The random up and down of the fan if left to its own device creates a noise I don’t want to deal with.
