I was asking about the 2 fans on your CPU cooler, which is likely the case though.
For fans at the top of cabinet, better configure it to push air out of the cabinet as hot air tends to rise up, better not go against physics.
2or3 x120mm or 140mm front intake fans for intake, 2or3 x120mm or 140mm top exhaust fans for exhaust and 1 x120mm or 140mm rear exhaust fan for exhaust are standard on almost all cabinets.
In the above mode the air will be sucked from the front and blown out from the top and rear.
So there won't be any hot air inside the cabinet.
As the GPUs will have 2 or 3 fan versions which will automatically cool the graphics cards by setting the fan curves.
And regarding CPU fan setup
One 120mm x25mm fan will be used as push and another 120mm x25mm fan will be used as pull
So thats why its called push pull setup.
This completes the cooling setup in the cabinet.
