Its not load based, it’s temperature based. I would take steps to make it run cooler like repasting if you’ve had it awhile (PTM or NT-H2 works), using it on a desk so your fan isn’t getting choked, and stuff like that. Another thing, what OS and hardware are you using? The fix isn’t software or firmware its pretty much just that fan noise is a fact of life. Other laptop manufacturers throttle their cpus to be quiet, but frameworks are set to run cooler to improve performance at the cost of noise levels (slightly). As a FW13 user myself, I would say it’s really not bad at all after a NT-H2 repaste.
