'91 190e 2.6

My 2 front aux fans seem to run early and often. My Temps seem to be running normal (just above 80 on the run, closer to 100 in stop and go) but it seems my aux fans are going almost all the time - that I can tell when not at high speeds (with or without A/C). Sometimes If I come to a stop, they will not be running, but if I start the car within, say, 30 minutes, they will come on immediatetly with the temp gauge right around 80.

I have a '92 190e 2.6 and the aux fans on it do not kick on until the temp gets closer to 100 and they do not seem to run near as much.

Which is normal, and where should I look / check / change if needed to get them running properly?

Thank in advance,
