I am seeing the fans normally hover around 2300 rpm. At this speed I can't really hear them. GPU/CPU temps in upper 50's. This is during my normal morning workflow which is running several apps including Msft Teams video meeting. When I stop the Teams video meeting (but keep the app open), I can watch videos in my browser and do a lot of other multitasking with the fans staying around 1700. Two external monitors are connected, but to be fair, they're only 1080p. However, I have tried working through a 4K monitor at home, and didn't notice the fans get any louder than at my office (which is to say I rarely notice them at all).
This is the very base model, 5300M/6-core i7.
Remarkable. I'd kill for that... I have the same model and it would be at 4k-5k rpm normally in the use example you're giving. With Turbo Boost off it would probably stabilized at 3500 but stay there. That is still loud.
