Fan Cooling Setup

[Ehrix]

So I just finish building my PC and for some reason I just realized I did not think through my fan layout at all and messed it up pretty badly. I have the O11 compact case with the glass top option installed, the side CPU fans set as intake and the fans at the bottom of the case (yes below the GPU) set to exhaust. I now know that's really bad from the heat getting blasted at my desk and into my face and my GPU temps hitting upper 80s. Now I need help deciding the best fan configuration. I have two images below showing the possible setups I should do. What do y'all think is the better option. I can only have 1 fan in the rear since I have a water cooling pump taking up one of the slots so I would have lots of positive pressure. (Note: I have a Ryzen 9 9950x3D and RTX 5090; Green is intake and red is exhaust)

Option #1: 


Option #2:

Well, typically it would be out the top but.. not an option. I'd pick Option 2, personally. Force it out the large mesh rear. 

 

And yes, please fix the bottom fans, they shouldn't be trying to pull air away from the GPU but feeding it instead.

I just flipped my fans on the bottom (ugly side up now ill have to buy some new ones to fix the aesthetic inside) but im seeing a 20C improvement in GPU temps. For having no exhaust fan the temps seem really good still.

if you have enough intake and a free and open backside, you don't always need dedicated exhaust fans. My Torrent it sold with no exhaust at all, all fans setup as intake.

would having a dedicated exhaust fan help temps at all or would they most likely stay the same with 6 intakes.
