Good Fan Layout?

[Xanthic]

Hey, I hear people talking a lot about different air pressure and stuff, but I just wanted to make sure this will make sense before I go ahead with it.

Best graph I could do, but do you think it'll be good? (My graphics card is reference type, so it exhausts air by itself. My 2 120mm fans on top of my 240mm rad are at the top pushing the air out. Would adding a small 120 at the bottom help my graphics card with temps?
Thanks!

Edit: 2 front ones are intaking, back is exhaust, future bottom fan would be intaking

Looks okay. I may advice to not put the bottom 120mm unless you can angle it towards your GPU because a fan pushing air upward while the two fans in front are trying to blow air deep into the case for the GPU is counter-productive.

Will take it into consideration, thanks.
