EEEEEEEEEEEEEEEEEEEEEEEEK!!!!!!!!!!!!!!!
You mean it's still alive!

AMAZING!!!
If your fan speed said 0 rpm, maybe it had stopped.
Don't just say, " oh I think it will be fine now...."
It really needs a careful checking over and leave the case side off for a while and listen to see if there is a power failure in the fan circuit even if you get a new fan.
You have probably already damaged your cpu beyond repair, lets just hope your mainboard isn't stuffed as well.
It takes just a fraction of a minute to blow an AMD CPU with no fan running so get it fixed.
You might be lucky though, a friend and myself left the fan cable off an XP1800 for a few mins, it blackened the mo/board a bit , but the cpu lasted another 4 months!
