I haven't made a fan profile in a while, but when I was running reference coolers on my 5850s, man, I'd never ever let it hit 100%. Waaayyyy too loud. Even 80% was super loud.
I usually had it sit at 30% up to about 45C, then jump to 40% and ramp it up to 60% by 70C, then a sharp incline up to 80% at 80C, and stayed at 80 from there on out. I found a profile like that gave me the best performance/noise ratio as it only really got loud if I was really pushing it hard.
Yes - shader & core voltages are only for overclocking. If they're set to zero, it just means you don't have afterburner configured to let you change them (by default, Afterburner won't let you mess around with voltages).
I dont know what i was actually thinking not ever using this msi afterburner to begin with. feel like a complete tard cause i used to use amdoverdrive on the CCC and had to always manual control my fan speed. This is great best program any gamer could ever need!! Thanks for all your input i ran BF3 on ultra settings never went over 60c
