Loud fan blowing noise

OneTwenty8i · 09-06-2017, 07:55 PM

I have a 128i n51 with about 25k miles on it. I live in North California and it gets hot here.

There has been 2 times where I have turned my car on and its made a very loud fan noise coming from the engine bay, like the fan is working full blast. Its worrying me and I was wondering if anyone had info on this? Thank you.

sounds like water pump or thermostat.

Could it just be the very large radiator fan? Sorry if that's too obvious
