MK4 extruder / heatbrake fan speed during printing

Hi! I've question related to MK4. Suppose that room temperature is around 21-22C and I'm printing with hotend temperature set to 225C.

Question: What is yours extruder (heatbreak) fan speed??

Mine ramps up to 8000 RPM most of the time (100%) and it's very loud. Heatsink temperature is around 37-38C. Comparing to MK3s Noctua's a it is night and day difference. I know that this Delta fan has higher airflow rating but I'm wondering why it is running so high...
