If it howls all the time, locate the bad bearing and replace it. It will eventually fail and cause big trouble.

Also check for a belt one "row" off on something, as this will make noise and quickly ruin the belt.

The fan should roar only on startup and when "engaged". Some are lower than others, I can barely hear the one on the 280 (will probably be able to tell better when I get the exhaust leak fixed), but the one on the Volvo TD sounds like a jet engine when it locks up!
