I currently have a NZXT Tempest case but i feel like the stock coolers that come with it aren't very good. It feels like it's not sucking air out/in that well.
I don't know the specifications of the fans.
Top ones suck air from inside the case and blow it out upwards.
Rear one blows air outside the case.
Front ones suck air in.
** Does the side fan suck air in or blow air out?
So i was planning to buy some new ones to replace one Top fan above CPU (140mm), Rear Fan (120mm), Side fan (120mm).
