Overcooling problem

Alright folks.

Wats the name of that sensor that turns the cooling fan on? Cant for the life of me remember it or find it online. From what i hear it usually break in the off position and the car overheats. Mine has decided to be individual and break in the on position. Bloody cooling fan is on full whack the whole time. I'm thinkin its not too big of a job to replace?

I believe it's a relay on the E36. It shouldn't be too difficult to replace it.

I'm having this same issue....just started today. Parked the car and turned it off, walked outside about 10 minutes later and the fan was running wide open. My "Check Coolant Light" has been coming on also but the car is not hot and the doesn't seem to be any leaks any where. Have you experienced this also or is the fan just running wide open?
