I just purchased a X1 Yoga 2nd Gen and I'm having lots of fan noise. It will crank up with just one web browser open. I'm all updated with the BIOS etc. Does anyone have a fix? I'd hate to return the machine, but this level of fan does not seem right.

Reply to my own earlier message - My fan issue got fixed when I went through the process of installing all the latest Windows 10 updated. Not all of this happened automatically - I had to keep going back into the Windows Update and scan/start again. This included multiple restarts and a few failed updates from Microsoft. Eventually when all was finished and all the Lenovo updates (required and recommended) complete, the X1 Yoga works without the fan running almost all the time. I was able to set the power management to default settings again.

I have all the latest Lenovo Updates and Windows 10 updates. I have also reset power management to defaults, but absolutely no improvement. The fan is running constantly even if most of the time at low RPM. This is really disappointing.

I followed ThinkBox's order - Clean (out of the box) Windows... then Lenovo updates via Companion app - including supplemental/not required options... then pushed through the many Windows Updates in System/Updates... the last step took most of the day and many failed installations. Before this, I did change the power settings (see earlier in the thread) and this helps.

Clean installation or not using the default power management settings gives a slightly better response behaviour. But it entails the CPU boosting up the frequency occasionally, which seems to be a problem for Lenovo's fan control system. The Lenovo fan control is too aggressive in speeding up the fan instead of waiting a little bit while the CPU is boosting.
But I have another interesting observation to report. I work in two places: in one place I connect to the OneLink+ dock, and in the other place just to power/ethernet/displayPort. Doing basically the same work, the CPU temperature is higher when connected via the OneLink+. This in turn leads to more fan noise when connected to OneLink+.
