Quick question

[Anthony10]

When watercooling, if I have 4 fans on intake on radiators, do I need an exhaust fan? Thanks for the reply sorry I know this is probably a dumb question.

The obvious answer is yes. At the minimum, 1 is required to create a good positive pressure inside the case. However, if you don't need the exhaust, the probability of the dust escaping through the gaps in you case (pcie brackets) is very small. I'd recommend the front and the rear fans bring the air in and the top exhausting it out (If you want to make use convectional currents).

You should have a one to one intake to exhausts ratio. This is good so dust doesn't settle in your case. Some cases can have all fans as intake, cases like the Lanboy air. I would have at least 2 fans as exhausts or more.
