Temps look fine.
The fans: Change the rear fan to an exhaust. Typically you want the front fans (because they are lower) to be intake and any that are higher (usually on top or rear of the case) to be exhaust since hot air rises. But as long as you have a smooth air flow (good cable management) then your good. Right now you don't since they are all intake the air is colliding in the middle. Make that one change and your good.
