Dusty vid card

So, I opened up my case today to find quite a bit of dust around the fan of my card that i got about 4 months ago. I haven't noticed any performace problems, its just that im wondering if If i should do anything about it, and if so, what exactly to do. I have no experience with doing anything like this in the past. It's a HIS Iceq card, so it [supposedly] has a nice fan that came with it, if that makes a difference

Every once in a while it is good to dust out the computer, because stuff inevitably collects in the tower. If you have an air duster, thats probably the best solution. Remember, static can damage parts, so ground yourself before opening the case and handling parts.
