New pc build graphics card over heating...

[damando]

So I just did a new build for my stepson and he is a fan of Halo. He plays Halo,Halo CE and Halo2.
However the card I picked seems to overheat sometimes. Even though I have a fan blowing directly
on it as well as the fan that is on the card. Here are the specs of the build. I would like any
recommendations to try to solve the over heating problem just on the graphics card.
(I will get a split screen with a solid red color on top and normal screen on the bottom)

Everything was purchased from Newegg.com and the graphics card is no longer returnable through a RMA.

See if you can get anywhere with a RMA through Sapphire - good luck, their end user support is bad.
