A7V133 Rev. 1.04 and Rev. 1.05

Hey, does anybody know what's the difference between the two other than the new fan on the chipset on rev. 1.05? I'm just very curious, that's all.

I have been trying to find out something on this for 2 weeks w/o any luck. Where did you find out about the new fan? Also have heard there is a 1.06 too. Tried to call ASUS, but put me on LD hold which I can't afford. They don't answer emails either. . .
