I have INTEL NUC BOXNUC8I7HVK2 when turbo boost run, run simple google chrome and cooler rotates where fast with loud sound 5-10 second then everything is quiet. If i'm off turbo boost the cooler practically does not spin and the system works very quietly. This is normal? It turns out in the turbobus mode the launch of almost any application includes a strong rotation of the cooler?
What are the cooling setting in Bios ? My NUC8i7HVK works quiet and steady with Turbo Boost enabled. Such behavior of cooling (cooling fan speed fluctuation) fan I've observed in NUV7i7DNHE, however, not in NUC8i7HVK.
Do you also have Max Performance Enabled checked? If so, try unchecking this and then checking Balanced Enabled. Similarly, in Windows, run the Control Panel Power Options applet and select the Balanced plan.
