Radiator Fan Stays on for a long time..?

Hey what's up guys. I just noticed this today, my 95 4.6 tbird will go throught it's normal radiator/cooling cycle then the fan will stay on and not shut...i think.

I say i think cause just now i was sitting in the car at idle to see when the fan would shut....i sat there for like 7 minutes and it was constantly on..just the fan though...the coolant finished its cycle.

btw the cooling system is fine, like normal the temp gauge goes to like the O in NORM then the cycle will bring the needle back down to almost Cold. I did get the fan and fan motor and housing replaced months ago after the old fan motor burnt out and melted the fan with it.
