So my cabinet has come with 2 front fans taking air inside and one back fan emitting air outside I guess or just say it's in default as all manufacturer provide but I wanna install 2 fans on the top so which side should I install....I saw at Linux he had installed two fans in front with sealed bearings facing the cabinet meaning it's taking air inside the cabinet and back fan where the seal is facing the outside of the cabinet meaning emitting all the inside air outside and 2 fans on top again same manner emitting air outside

I'm really confused plz help guys
