My ThinkPad x270 (i7-7600U) operates without using the fan for most things; only when compiling things for more than ~15 seconds do the fan turn on (and when opening Slack). Can probably tweak it a bit more by adjusting the limits and/or adjusting the upper CPU frequency limit, but I haven't bothered.

I do run Linux, and have a fairly light-weight environment (dwm etc.) I don't know how much that matters.
