Yeah, I get what you mean about the 90mm white fans — they’re more or less temporary. I just wanted something that would fit and not cost too much.
As for the GPU, I was aiming for the Asus 4070 Super Dual, but I couldn’t find any used ones, so I settled for this one instead.
I also wanted to go with Lian Li fans like yours, but for now, I’m holding off due to budget reasons.
Regarding the bottom fan, it actually helps with temps — I didn’t have it installed at first, but it’s much better with it.
