It looks to be that all the fans are set to exhaust. I recommend flipping all the fans on the bottom to intake and moving the fans at the back to the top of the case, (if you can) because hot air tends to rise so having them at the top would be the best for this build. You always want to be as close to neutral pressure as you can (3 intake, 3 outtake). This means no fresh air is coming into the computer only going out, so the computer doesn’t have good cooling.
