High pitch fan noise
I hope this post finds everyone well. I have a quick question - I ran my 2010 E63 P2 pretty hard today in stop-go city traffic on manual mode shifting at close to redline never passing 4th gear. As my oil temp reached over 113 (celsius I believe), a high pitch fan noise that was actually fairly loud started. When in my garage, I noticed that it came from the left (passenger) side. Can I assume it is the oil cooler and has anyone experienced this and is this normal on hard runs?
Would appreciate any feedback. Thanks.

Yes that is the fan to suck air over the oil cooler located in the left from bumper area. I forget the temp at which the fan comes on but that is perfectly normal. It sucks the air over the cooling core when there is not enough airflow from driving to keep the oil at the desired temperature.

It probably doesn't turn the auxiliary fan on at 225, that's not a high oil temp. 240+ is usually where the car starts to correct for it, first by requesting more engine fan, then with the aux fan on the cooler if it has one.
