GPU Very Noisy

I have an xfx 7970 dd edition and its ridiculously loud under load and gets to around 80 degrees. I have 5 fans that all intake and I have the NZXT switch 810.

Any things to reccomend that can help me reduce temps and noise?

Have you tried turning it of and on again?

I had the same problem with a 7950 that I got from them and I just ended up rmaing it. I now have an msi twinfrozr 4 7950 and it's muich cooler and much quieter. 

I'm going to try changing the airflow in my case first and if it doesnt work ill probably have no choice but to rma it
