Okay, that sounds like a reasonable fan profile. I should point out that the fan profile you see in Afterburner is only in effect when Afterburner itself is on. When it's not on, your graphics card resorts to it's built in default settings. So, if you load your card now (with WOW), with Afterburner on (the program can be minimized, just not closed), what temperature does your card reach? Are you still hitting 90 degrees?
