I use Q-Fan and for a period of time (I believe it was with BIOS 1201) I did get the CPU Fan Error. It's been a long time since I've seen that error now tho... or maybe I just haven't been paying attention because I set "Wait for F1 on error" in BIOS to disabled and unplugged the case speaker... if I'm getting the error, I'm no teven aware of it, so it's as good as not getting it :P
