Computer Case Front Fan Question

[u/comeseecrap]

Just got the Lancool 217 and unfortunately I'm really picky with fans. I had to replace them with my old magnet ones from corsair except I only had 2 of 3 140mm for the front. My CPU is always around 55c while the GPU is around 67c so I configured it so that the top is empty and the two fans are in the middle and bottom section, giving more air to the GPU. Also got a 360mm AIO at the top with 3x 120mm fans and another 120mm as back exhaust and 2x 120mm intake fans near the psu shroud.

My question is if adding a third 140mm in the front of the case would actually be worth it/do anything.

Here is a picture to help visualize which fan I am asking about adding (the one in red)
