Cooling to OC my Radeon 5770

Well Christmas is coming and I put 2 120mm case fans on my list. Regardless of rather or not I get them, I will have some by January.

Now what I'm planning to do is OC my video card when the time becomes necessary.

My current setup is a 120mm in the front for intake. And 2 exhaust fans, a 140mm on the top, and a 120mm on the back.

The case has an option for 2 side 120mm case fans.

How should I orient these fans and how much should this help to OC?

Thanks for any responses.

i assume the two fan slots are at the top and the bottom of the side? if so, then i would have the bottom fan as induction, top as exhaust, as heat rises. However, adding more case fans isn't going to help a graphics card much, i assume that your Graphics card has a fan on it (or two) usualy these fans that are on there can handle overclocking and keeping it cool with ease.

if you want to do serious overclocking, check this out: http://www.amazon.com/Arctic-Coolin...AM4Y/ref=sr_1_2?ie=UTF8&qid=1322617115&sr=8-2

intake on the front, intake on the side exhaust on the rear and top...
fans on the side will help cool gpu and cpu considerably!!
as the fans on the side will keep constant cool air forced to the gpu fans!!

if the gpu fans suck air in and exhaust hot air out of the back themselves thats even better!!!
