[SOLVED] Question about top case fans

[RuffRidersEvo]

I plan on getting two top case fans because it’s just empty on top since i do not do liquid cooling (i should) but would i need a radiator for the fans? Or can i just smack them on top? Also should i get 120mm or 140mm?

You can put them at top but they will also have to be matched by equal number of intake fans to do any good. Liquid coolers come with own fans.
