The fans in my Yoga 13 are loud and they spin all the time. Is there anything I can do to change this?
Yes, with a caveat.
Lenovo has made available a special version of Yoga's Embedded Controller (EC) which contains an alternate thermal table for users who feel the fans are too loud. This alternate thermal table will delay the initial spin up of the fans, and will spin the fans up to a lower initial RPM than the default EC.
Caveat: While the fans will run less and at a lower RPM with this special EC, this means the system's operational temperature, and therefore surface temperatures, will be somewhat higher.
Below are links to download the special version EC with the alternate thermal table, and to download the default EC with the manufacturing default thermal table, so users may try the special EC, then revert back to the default if desired.
To appy either EC, you will need a USB key (flash drive) that can boot to DOS. The download files contain step by step instructions for applying the EC.
For advanced users: You will need to switch Boot Mode to Legacy to boot DOS, run EC.BAT, then switch back to UEFI after you have flashed the EC.

NOTE: If you have updated to the special version and experience issues with Intel Rapid Storage Technology, please update BIOS to version 55 or later. BIOS 55 may not also include the update to the EC which controls the fan, so updating to this BIOS without first updating from the first link above is unlikely to change fan operation.
This update does not really do what I hoped. My hope really was that the fan was stuck in "on" by mistake, and that this would cause it to spin down most of the time. This is not the case. At normal load, the fan runs just like before. This update does not change a thing other than slightly delayed start to the problem.
In essence, the fan noise is still too loud for a study hall, library or a meeting in a quiet room, even after applying this update ): Unless there is a more radical update in the near future, I must return my Yoga 13 due to this issue ): Makes me sad, since its such a great machine in every other respect.
A question about the note: I understand that if I have already updated the BIOS to 55, without first operating the EC change, there is nothing I can do about the fan noise?
Note book fan control. It allows you full control over the fans. You can create a thermal template or just turn the fans on when you think it needs it. Just be careful not to roast the CPU
Hi folks. It's january 2014. I just bought a yoga idea pad 13, realised the fan noise and went throught the forum. The mashine was allready equipped with a 66cn55ww Bios but i updated to the above mentioned ec version 66ec42ww. fan is still loud. So I kept pn searching for other articels. An i found a hint that there are power managers available with fan control. My one does not have this (may be it's a problem for the German version i am uisng?). So: Where do i get a power manager with fan control. I would also us an english one. Thnx in advance.
