Best fan placement for optimum cooling in this case?

Hey forum, I recently built my pc, and it's a monster. However, I have a problem with cooling, ESPECIALLY with my giant GPU, as I neglected to buy case fans and I currently have one rear exhaust fan (not including the cooler master cpu fan that blows toward that one). I bought two 120mm fans off of newegg from cooler master (it was quite the deal). I was just curious as to what the optimum fan placement would be for my particular case. Links are below and all opinions are welcome :) thanks!

Thanks again :D

Hmm I haven't looked closely at the specs of the computer, but this should be the general layout. The front two fans should be intakes, so that fresh air can go into the computer. The top two fans(if there are mounting points available) should be exhaust. This will keep the airflow positive because heat rises. Back fan should be exhaust. Bottom fan(if there are mounting points available) should be intake. Though this mounting position isn't ideal if your case doesn't have a dust filter on the bottom because it'll suck in dust. The side fans should be intake so that it'll cool your GPU directly.

Thanks for the reply! It appears I can have up to 8 fans installed, but that kinda seems like overkill. I'll already have 3 installed, and I think I'll put one on the side with my gpu (an intake) and one on the front taking cold air in. Should I buy a few more fans just to improve my cooling that much more? Also, my motherboard only has 2 fan plugs, can you plug extras straight into the power supply?

Nah, I think the amount of fan's you currently have/planning to install should be enough. As for the fan headers, I think there are adapter available.

Here's an example: http://www.moddiy.com/products/Single-Braid-Molex-4%252dPin-to-4x-3%252dPin-Fan-Cable-(15cm)-%252d-Black.html

I would do some searching before buying the above. With the adaptor, you're powering the fans with a molex coming from the PSU, which doesn't make you use a spot on the motherboard. Instead of 4pin, you could search for 3 pin adapters because the 4th pin is only used to control speed, which is pointless when you power from the PSU. If you do power from the PSU, just know that it'll run at max RPM because there is no control over the speed.

Max RPM would be fine. I'm not that anal about fan sound as long as there's adequate cooling. Thanks for the help!
