That would help a lot with the temps, but get the 9700 zalman. I got mine for 45$ from newegg with 35$ instant savings. It was cheaper than the 9500 when i got it.
It has a 110 mm fan and will work on your socket. You can get a orangish one with a blue led or a black one with a green led fan. It is really good and comes with a fan controller.
I didn't notice any temp difference yet, but i run games for 2 hours with the fan turned all the way down and the temps don't change. I am sure it will help as soon as i start OC'ing.
Make sure to get some Arctic Silver 5.
