Hey everyone, I need expert advice about a good way to setup this case for best air cooling. As you can see in the HWmonitor pic, my max temps after running Prime95 for maybe 10 seconds jump from 38-42 degrees Celsius (under no stress) to almost 70C. This also happens when playing my games which results in occasional crashes. The setup resulting in these temps is actually my worst so far. My best is with a max of 55C on one or more of the cores.

I barely OC the cpu using the Gigabyte tweaker to 3.5 Ghz, up from 3.3Ghz. I have a Thermaltake Silent 1156 cpu cooler on the cpu. Being that I have a cpu cooler and I barely OC the cpu, I would prefer that maxed out gaming not push my cpu over 50C.

Does anyone have fan setup ideas for me? To help, I'll list my previous and current fan setups, and the pictures of the case can be used to help you understand.

Overall # of fans: 3 x 200mm and 3 x 120mm

Current setup: Exhaust - Top 2 (200mm), Rear (120mm) ; Intake - Side 2 (200mm and 120mm), Front (120mm)

Previous 1: Exhaust - Top 1 (200mm), Rear (120mm) ; Intake - Top 1 (closest to front - 200mm), Side 2 (200mm and 120mm), Front (120mm)
Previous 2: Exhaust - Top 2 (200mm) ; Intake - Rear (120mm), Side 2 (200mm and 120mm), Front (120mm)
Previous 3: Exhaust - Side 2 (200mm and 120mm), Front (120mm); Intake - Rear (120mm), Top 2 (200mm)
Previous 4: Exhaust - Side 3 (200mm and 2 x 120mm), Front (120mm) ; Intake - Top 2 (200mm)
Previous 5: Exhaust - Side 2 (120mm), Front (120mm) ; Intake - Side (200mm), Top 2 (200mm)

Important NOTE: I always faced the cpu fan in the correct direction for proper airflow (i.e. if exhausts were at bottom/front I faced cpu fan exhaust that direction, if exhausts were top/rear I flipped fan exhaust to face that direction).

I can't remember what my best setup was. It was Previous 3 or 4 as my best guess. Computer pics are in an album link (below) at imgur.com. The HWmonitor pic (below) shows my temps with current setup seconds after stopping a Prime95 torture test.

I think the top two should be intake and the rear exhaust. This will force in cooler air. Never mind convection. I have no reason to believe aiding convection really does anything, as any airflow convection generates is pitiful compared to air flow created by a fan.

I'm not sure I understand what you intend for me to do with the other fans though? I can turn the top 2 toward intake right now and run Prime95 and post results. I'll leave rear as exhaust as you said.

However, what do I do with the other fans? If I leave them as they are then I will have all intake and one small rear exhaust.

Ideally only one side of the case should be exhaust, so you can be sure air is getting across all the components with none the cooler air being stolen.

So see if turning all those fans into intakes except the ones mounted on the rear of the case helps.
