special materials needed?

Hello,

I have an MSI 780 gaming gpu, the 2 fan thing that dumps all the heat into your case. I'm thinking of making a shroud to go around the fans with a 120mm fan at gpu powerplug end blowing air through the shroud and out the back (remove the pcie slot covers). Do i need special perspex(plastic) and glue for this due to potential temperatures or will any perspex do the job?

Thanks

Fractal Design R4, that's why id like to exhaust the gpu heat out instead of into the case. I am talking about a shroud the thickness of a 120mm fan...not one that just skims over the top of the gpu fans; I don't do sli so i have all the room under the gpu to use.

I thought of that but the 2 fans on the gpu cover most of the card, the most effective way would be my idea to funnel heat towards vents at the back where the pcie backplates are; it will be a big and ugly shroud but it should do the job, my only concern was needing special plastic to avoid warping or smelling if it gets hot.

I don't have any overheating issues, i just thought if i directed all gpu heat out the back, my case would stay cooler allowing me to slow down all my fans a bit more; i'm trying to get as silent as possible.
