I'm recently got a B Grade AMD 7950 which is a nice performance increase on my old Nvidia 560, however, it is rather loud due to it hitting 70c in a few games Due to this i was wondering if under volting would have any real impact on the temperature. Has anyone else tried under volting to lower temps?

Undervolting to reduce temp

I under volt my 7950 to reduce the heat.
It really depends, I tend to try and squeeze out as much performance out of my systems as possible using stock/near stock voltage. If you care about reducing temperatures/heat output, then sure, go for it. But often a more effective solution might be looking into the external factors affecting the cooling, like the case the card is in, any nearby objects that might make it warm and how efficient the airflow is inside the case.
You can also adjust the fan using a program like MSI Afterburner, these cards are designed to run at much higher temperatures when needed.

I did a lot of undervolting on my 780 to reduce temps and necessary fan speed. It's just like overclocking, so you'll need to ensure that you are stable at the new voltage.
Also adjust your fan curve if you are happy to let the card run a little warmer. I doubt there would be any measurable side effect of letting the card run at 80C as opposed to 70C.
