[stextbox id=info]Update: This is an update from “Bloo” on the Lenovo forum thread surrounding this issue. tl;dr
I’ve approved an update that contains a new thermal map that spins the fans up later and to a lower RPM. We plan to release an update to apply this new thermal map, along with a package that will restore the old thermal map in case anyone wants to backlevel.
[/stextbox] I just purchased (11/19/12) the new Lenovo IdeaPad Yoga 13 from Best Buy and upon unboxing and turning on for the first time, I noticed the fan constantly runs. It’s rather annoying! Some research led me to the Lenovo support forums where there are plenty of others complaining about this. I’m going to dig into the problem a little more intimately soon I hope to see if it’s a power management issue or if there are some fan speed control settings hidden somwhere. There are 3rd party applications I’m aware of but I want a response from Lenovo on this. I’m contemplating returning this – it’s that annoying. It seems (last updated today) that one consumer returned their purchased unit to Best Buy from a different city and the new system does not exhibit the fan noise issue. I am awaiting response as to which model he/she picked up as a replacement. My affected model: Mfr Date: 12/10/28 Model: 20175 PN: 59340248
