Plus both of these fans are compressor style, so they can really move air through their respective channels.

The video card uses it’s own exhaust channel out the back, as does the cpu cooler.

I think OP is saying there’s only an in-vent but no out-vent (or vice vera), so the hot air won’t actually flow anywhere. It’s like sucking through a straw with a big chunk of something stuck in the other end, very little water/air is actually gonna move through the system

EDIT

though on a closer look at the picture i see one addition is the card but another addition is a big extra fan, so forget what i said
