gpu settings help!

[avenstin]

my graphic card is a xfx r7870 double d tahiti (le) and i need help on adjusting my card. on most games i set the fans temperature to about 60% to 70% and my card's temperature stables around 47 to 55 degrees rarely hits 60 degrees. the problem is tat sometimes when i play games my gpu usage would jus boost up high from like 30-40 to 80% usage and its loud and starts to vibrate when im playing alan wake and he was jus talking on the phone. Is there some kind of adjustment i can make for this? is this an over clock setting? is it normal? is my gpu good at 80% load and up? i really dont like it.

Wouldn't you feel a bit short changed if your graphics card only ever used <50%?

If you just let the drivers automatically change the fan speed using the default settings you'll be absolutely fine, the graphics chips are meant to work at much higher temperatures, so only letting them get to 80 or so is no biggy.
