Heater Fan Squealing

While driving at above 120 km/h a squealing noise appears. I first thought it was the heater / air conditioner fan but after turning off the heater fan the squealing continued.

I started to think it had something to do with a whistle from air flow.

It is quite LOUD and not something I can live with. It was very hot that day. I will continue to monitor and see if it continues.

Input appreciated.

I don't hear it when it's necessarily hot out because it was cool today, and I only hear it when it's idling. When I rev it it goes away.

I'm not sure if I'm experiencing the same thing as you.
