I am running SLI 2080 Ti cards in a Corsair 750D case and the top card is just getting way too hot. I know the open-air coolers are not the best for SLI, but it's what I'm working with. I believe I could knock the temps down a lot if I got better airflow in my case. I'm thinking I want to do the following -Replace front 2 intake fans and rear exhaust with something more powerful -Add 1-2 intake fans on the bottom -Add 1-2 exhaust fans on the top I just need to know the strongest fans that won't be extremely noisy. I don't expect to run a silent PC so as long as the noise isn't egregious it's fine.
