Re: X1 Carbon 6th gen : Fan Noise

Just to add my experiences to this.  X1G6 - running Win 10 1709 - Custom corporate Build at Lenovo Factory using ADS.    Receiving complaints from users when plugged in of the fan constantly running.  Machines are running absolute latest drivers and 1.25 firmware.  

 

I've run the powershell scripts, no difference.   The only thing that makes a difference is that if we kick the Maximum Processor State from 100% to 90%, then the problem goes away, but we're also pretty much **bleep**izing the machine at that point (if you wath the CPU speed in Perf Mon, it never goes over 1.9Ghz when at 90%, but if we kick it back to 100% it will go upwards of 4GHz.   

 

 

The fan is an issue whether plugged into the Thunderbolt 3 Dock, or just an AC adapter.   There is no fan noise at all when not plugged in/running on battery.

 

I'm hopeful that it's a driver issue that will fix it as others have suggested

 

 


Disable Thunderbolt Service and try with external power (w/o TB 3 Dock). If this solves the problem then we know it's the TB issue that people have been complaining about.

It has been a few months since I got the unit and I'm glad to solve the overheating issue with you guys here. However, I've been experiencing the power limit throttling since I got the laptop. Do you guys have the same issue?

Re: X1 Carbon 6th gen : Fan Noise

I have a 2016 X1 Carbon Yoga and the battery life is pretty much non-existant. I can't get more than 4 hours out of this sucker, at the very most.

Also the fan would be running all the time if I hadn't shut it up using TPFanControl.

 

I read that this year's X1 has excellent battery life, up to 12 hours or so.

But what about the heat/fan issues? I can't stand noise, the fan has be OFF 99% of the time, especially when I only do simple office work.

Is it possible to (more or less) turn off the fan or will it quickly overheat, unless you limit the CPU frequency?

 

Before my X1 I used to have Yoga 2 Pro, and that thing was amazing.

Fast, light, absolutely quiet and probably about 8 hours of battery life.

Surely Lenovo should be able to build something like that for the business market?

Thanks.

We just deployed 1500+ X1G6 and that is our largest complaint from our users - the fan noise and heat generated from the units when plugged in.  We've been working with L3 Support and so far they haven't been able to get us any resolution - I feel like they keep pushing it back on us telling us we're nuts.

Wow. I really can't believe they're unable to fix that over the course of several years?!

Here I am willing to spend another 2400$ or so because they last computer I bought from them has such a flawed design that it's impossible to use without the AC adapter plugged in all the time, and they don't have anything decent?!

The Yoga 2 Pro had cheap finishes, but other than that it was great. And at twice the price they don't have a working laptop?

Come on, I don't want to buy Dell...

@BrianSu

Even though these may solve OP's issue.

Would you please explain what are the command doing? esp. if can go through any windows setting/choices? so that people can reservse the changes.

 

Thanks!

 

Edit_1 : Found this description, those setting may relate to CPU power threshold esp. on AC power?

But where can these settings be visible? e.g. at Power Options or  under gpedit\admin\system\power manangement?

I remember saw these somewhere, but now gone?

----------

Edit_2:

Suprisingly, I found Windows 10 seems changed the Power Options\ Advance settings from Build 17134.228 to 17134.286(my latest)

Hello

 

If you want to see that same settting in windows power management GUI, just open regedit, find:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\36687f9e-e3a5-4dbf-b1dc-15eb381c6863

 

and set DWORD:Attributes to "2"".

Reopen power management window and you will see new setting "Processor energy performance reference policy" under "Processor power management group".

Re: X1 Carbon 6th gen : Fan Noise

I recently got a X1C6 with i7-8550. I want to get a dock and have been debating between the Pro/Ultra or the TB3 dock. After reading this thread, I'm wondering if heat and fan noise might be a consideration when selecting a dock.

 

Some of the other posts in this thread mention disabling the TB service. With that service disabled, the Pro/Utra dock would still work, but presumably the TB3 dock wouldn't. On the other hand, the TB3 dock would allow the laptop to be used with a cooling pad under it, while the Pro/Ultra dock looks like it wouldn't, because the dock would obstruct the intake vent on the bottom of the laptop.

 

Any thoughts on this?

Using a cooling pad isn't addressing the issue that causes it to be hot in the first place. The heat will still wear your battery down quickly and your CPU's life will be shortened.

Any update on this? My fan keeps coming on even when doing light tasks. I'm on the latest BIOS 1.34.
