High Idle Temps

[Jayman0101]

So I've been noticing that when idle, my graphics card's temperature is rather high. (By idle I pretty much mean not playing any games). I will say that the venting of my case isn't the greatest, as it isn't anything custom, it was bought in a store. There isn't any dust in the fan as far as I know, and nothing is blocking the fan. This card(ATI Radeon HD6770) is also known for running warm. Currently, while writing this, it's at 51C. Is there much I can do to reduce the temperatures? It's only a few months old. Any help is appreciated. Thanks!
EDIT: I haven't had any performance issues or crashes, everything is working fine.

51c isn't that bad for idle to be honest. What is it like while playing games?

Your card should be safe at 51c idle, but if it starts hitting like 70 on idle then you got a BIG problem.

Ok thanks. I guess I was just concerned because overall, the fan on it is rather loud. thanks
