5830 vs 5850 Fan noise

[Net]

Is there anyone who had both of them that can comment on how they compare, under full load, for fan noise?

There is really a lot more variance between, for example, a 5850 made by one company and a 5850 made by another company. You need to specify exact models if you want any useful answers.

i have the sapphire xtremes and the 5830 is a 92mm fan and the 5850 is an 80mm.from 60% on the 92mm fan drowns out the 80mm.but cooling wise the 5830 @60% equals the 5850 @80%(this is how i ran bitcoin).under 50% both are quiet
