I modified my computer case so that I can add more computer fan to make my computer cool this summer. I need your thoughts on how I can improve my idea and I'm open to all of your advice.
Fan Position (The blue circles are the fan's location)
At the side I have to intake blowing fresh air at the motherboard and at the top and back I have Exhaust fan blowing out hot air. The computer fans will be powered by 12v adapter (recycled) so that my power supply wouldn't be overloaded. I need some practical advice, I don't want to spend to much on this!
