[s-cars] strange noise in S4

My wife drove our 94 S4 to work this week. After 4 days she said " by
the way its making a funny noise but it is driving ok".
The noise seems to be coming from the front behind the radiator. No
leaks, overheating, charging problems, or oil pressure issues. Does not
sound like metal grinding or squealing more like a rhythmic vibration
of something against plastic or light metal. The fan comes on high as
soon as the car starts up. There are no fuses to pull or metal link
like in the 20v 200....... so what is the quickest and easiest way to
eliminate the fan as the source of the noise? Don't want to run the car
for any length of time for fear its something like a timing belt
hanging on by a thread. Hoping that is not the case...... TB was
changed about 60K ago.
In the past I have had the tendency to waste a lot of time in futile
attempts at problem solving while a really obvious solution was staring
me right in the face.
TIA for any suggestions
PS I have read many posts in the past praising the simplicity of these
older Audi engines in comparison to the New Audi stuff. To me this
engine seems to be a complex maze of sensors and wires compared to the
tractor like 60's era Volvo engines I have the most experience working
