  1. if their idling that cool i would leave the system as is
  2. If you mean closing off the bottom one in front of the psu and the front one, where you have blue arrows, then no. That is where cooler air is being pulled into your system

    It would have been easier if there are punctuation marks in the right place. Here is my guess of what you meant:

    With only a single intake fan, probably your case will have negative pressure so it will suck the air from the open back which is hot because the exhaust of your CPU cooler also goes there. If your PC's back is right at the wall or enclosed, it will be worse even.

    So, yes, it is better to restore the back plates & close it up so all your intake will come from the front. Looks like you put a filter at the bottom hole. It is good to prevent your PC sucking dust from the floor.
  5. I have 2 intakes one in the front , and one 120mm on the side to push n air toward my gpus and its about 3 feet away from the wall ...

  6. Put the back plates back on, but only because it will look nicer, what are load temps? I'd guess that it wouldn't make any difference whatsoever as most backplate things are meshed anyway
  7. i dont get over 65c in Skyrim,MW3 BF3 etc...
  8. and my back plates are solid metal

    Ah that would make the difference. But put the back plates on anyway. It is designed to be there. You have more than enough airflow & removal of the back plate wont matter much either way.
