X390 Excessive fan running when plugged in

2019-07-18, 23:18 PM

Brand new X390. Noticed very active/excessive fan spin when the unit is plugged into charger (but not operating under particularly high system load).  The fan quiets considerably under the same system conditions when I unplug the charger cable (only run on battery).

 

I saw this post referencing an older operating system version -- appears to be the very same issue.

I'm running:

Intel i5 8265U 1.6 GHZ

Windows 10 Pro 1809

 

Suggestions?

 

Thanks!

Quick update: Day 3 operation and feel confident this is a setting issue.  Fan continues to run excessively, but the second I unplug the charger, it goes quiet.  

 

Any ideas to help?  My call into Lenovo (not particularly informed rep) ended with a suggestion to do a return.  Surely, there's a better option than that?

I'm having the same issue - while plugged in the fan speed is insane, and my usage is essentially idle, but there is quite a bit of heat coming out. So it appears something is running while its plugged in, cause as soon as I unplug, while contiuning the exact same work the fan goes straight to idle and the machine is awesome.

I have the same exact problem.  I purchased a brand new Thinkpad X390 Yoga in December 2019 with an 8th Gen i7 processor and 16 GB of memory.  When plugged in, the fan runs regardless of the system workload. As soon as the power cable is detached, the fan reverts to a more normal running cycle (i.e. it rarely turns on). 

 

Were you able to find a fix for this?

 

Thanks.

Were you able to find a solution that better control the Lenovo x390 fan when plugged into the AC adapter?

I have same issue with Linux Manjaro. Before this new brand, I had CarbonX1, 3rdGen. It was completely silent. The X390 Yoga is a total noise in comparison to my old Carbon X1.

I also noticed this issue with  my x390 plugged into a USB-C docking station.

For me, this was actually related to a Windows setting on the battery. If you left click the battery in the system tray, you have a slider with 3 options. (Better Battery, Better Performance, Best Performance)

When I have it plugged in, I want best performance so that is what I set it to. On this setting the fan runs constantly. The middle setting it's a little quieter, and the Better Battery setting is very quiet.

I guess I will wait to see how performance is, but I just need it for general office work, nothing too crazy.

I am experiencing the same excessive fan noise in my X390 even basic apps running. did some research and found not necessarily a fix but somewhat band-aid to the issue. Try installing TPFancontrol https://sourceforge.net/projects/tp4xfancontrol/

 

After I installed the app the fan noise has improved. I hope this helps.

Thanks - thinking its just crappy bio code or something with the fan controller. Though using the Lenovo Diagnostic Tools, the temperature sensors are showing the motherboard at like 80/90+ Celsius where everything else is in the 40s or just over 50 degrees - all with essentially idle/almost nothing in the background on a clean/clear hard surface. Got some other pieces to address via warranty, so will be placing the temperature stuff in there as well.

Its somewhat odd, the only time the fan noise behaves loudly is when you connect the AC, one thing I noticed when Battery Charge Threshold is enabled also the fans noise gets loud. I am assuming its more on firmware issue than hardware, however it is worth to check the HW part hence our devices are under warranty. Thanks!
