Man how I wish I had come across this post before doing my bios update today.. Fan control completely gone from Nerve Center and fn + Q command no longer let's me keep fans running at max speed while gaming.
On top of that I recently had the issue where they rolled out the 15inch keyboard lighting firmware instead of the correct firmware for my 17inch Y740, completely messing up the backlights.
I had to find the old firmware and revert to that in order to fix this issue.
But up till now it seems this fan control issue persists, and I am definitely seeing the effects of it while gaming.

90-95 while gaming. No fan control option, no fan speed monitoring option, just 3 thermal modes in Lenovo Vantage, but they do not change the fan speed, just increase or decrease power. Waiting for new BIOS version.

I am here with a new Y540. And it gets very very hot very quickly (on linux there's no way to control the fans even with the thinkpad_acpi module).
Is Lenovo doing something about this?

After the last update with the thermal mode on performance my CPU thermal throttle during the gaming, before the update using the Fn+Q function I rarely reached 85 degrees on CPU.
Please restore the old Fn+Q mode or allow users to create custom fan profiles

Okay everyone. I contacted lenovo live assistance and they say they were not aware of the issue. I think we should all go to the contact ways to contact lenovo about this is we want it fixed.

PLEASE listen to your cusotmers and users. I bought the Y740 specificly becaue it had the ability to push itself to 100%. Please for the love of god bring it back. My temps went straight to over 95 becaue of your new fan curve.
