Did you properly bleed the system? Maybe a fault water pump or fan not running? .http://forum.e46fanatics.com/showthread.php?t=825186

Is there a squeaking sound while the car is running? That's a sign of a failing water pump. I'd check out the water pump.

Water pump is fine. Fan works properly, but I'm thinking maybe a computer problem. Might not be getting signal to kick in?
