Legion Y540 Thermal/Fan Control, or Extreme Cooling?

2019-07-11, 1:06 AM

Hello,

 

Just recently purchased the Legion Y540, and I'm trying to figure out how to control the fan speed. I've been through 3 chat sessions with Lenovo, no luck there. So far it seems the only way to control the fans is with Extreme Cooling through Lenovo Nerve Center. I've downloaded the most recent version of this program, and that function is not there. Only 2 of the 4 functions are there (Prevent Mistaken Input and Network Priority). Looking through the forums, this seems to be a common problem with Nerve Center on other Lenovo computers. Lenovo can you please fix this program?

 

I have updated my BIOS to BHCN28WW (Also tried BHCN27WW, as provided by the Lenovo Support Specialist in chat), the most recent one, I've uninstalled and reinstalled Nerve Center, no luck anywhere. Lenovo Vantage seems to have very limited control option ("Performance Mode" = "Higher CPU usage, higher fan speed"? What if my GPU usage/temp is high but my CPU isn't, so the fans won't kick in?).

 

Just looking to keep my gaming laptop cool while gaming. Any help would be greatly appreciated!

That is why that I will probably change Y540 to GL73 from MSI, due to fan control. My lenovo stays on 70 CPU and 66 GPU when playing GTA V and 76/72 CPU/GPU when FULL stress test. I want to slow down fans a little bit because noise is horrible!

Yup, manual Max fan control is sorely being missed on y540. Don't know even Lenovo is listening and doing something about it. Fn key disable is also not in BIOS

There is NO SOLUTION for FN+Q functionality because Y540 doesn't support it.

Fan speed behaviour can be only automatically controlled by the system depending what mode you choose via Vantage app.

Press the directional arrows on your keyboard to select "System Monitor." Press "Enter." Select "Fan Control" and then select "CPU Fan Speed Control." Switch the control from "Automatic" to "Manual." This allows you to manually control the CPU fan speed by percentage.
