PC Case temp problems

Hey guys, I have recently built a pc grow box and have my seedling in it now. But when I put the side panel on the temps get up to 105F sometimes! I have 2 exhaust fans at the top and 1 intake fan towards the middle(see pics). They are only running on a 9v adapter right now. Would switching to a 12v make a big difference? Any other suggestions from people who have built pc grow boxes on keeping temps good? Since the pics were taken the inside has been painted white.

Help a brotha out! Haha

well make sure your intake is larger than your exhaust.
and an oscillating fan to move the air around.

Switch each of your fans to a 12v adapter to get the most out of them. also make sure you have negative pressure inside the cab, meaning that it pulls air in. With two exhaust fans you should be okay, but depending on your lighting you may just need another one.

I had the same problem with my pc case. I started off using 80mm for intake an another for exhaust. My temps were way too high so i added a 120mm fan as exhaust and made both 80mm intake. Now my temps stay at 80.

Switch to 12 Volt, get biger fans, have a fan blowing air in at the top and at the bottom of the case, thats how i solved my problem.

Alright thanks! That helps a lot guys.
