Yeah I guess I don't have a ton of experience here outside of mac laptops, but the idea of a PC laptop that only kicks in the fans when truly intensive tasks are being run sounds pretty nice.
My experience has mostly been that when any work is being done, the fans spin up. It's jarring when you're trying to focus on the problem at hand.
You need to find your fan rpm/noise threshold. On my laptop the fan becomes noticeable above 2500rpm. Someone commented about adjusting the fan curve (I have no idea how), I just manually capped the CPU performance with a powersave profile instead.
