Re: Lenovo X270 noisy fan

2018-10-23, 13:56 PM

Agreed, cooling solution is terrible.  We have all generations of the x series in our office going back to the x230 and the x270 is definitely the worst.  I'll probably be moving back to x250.  

 

I also get micro stutters where the computer just freezes for a second randomly.  I'm going to re-evaluate using Lenovo moving forward.

Re: Lenovo X270 noisy fan

My X270 has this same issue when docked.  The fan runs constantly at max speed whenever the laptop is connected to the Ultra Dock (one external p24h monitor).  I have done a complete system restore, updated all drivers and BIOS to latest versions.  Setting Windows [Power Options] > [Advanced settings] > [Processor power management] > [System cooling policy] > [Plugged in : Passive] has no effect.

 

I reset the BIOS to defaults which I noticed sets [Config] > [Power] > [Adaptive Thermal Management : Maximize Performance].  I changed that to [Adaptive Thermal Management : Balanced].  No effect.

 

I tried using TPFanControl.exe 1.0.0.61.  That is the only thing that has stopped the fan from running constantly.  When set to [Mode : Smart] the fan will gently spin up occassionally as CPU usage peaks but otherwise stays quiet.  When switched to [Mode : BIOS] the fan immediately spins up to 4000+ rpm while the cpu temp remains unchanged at 54°C.  I really dislike the idea of using this utility to override the system cooling policy all the time.

 

Given the age of this thread obviously lenovo is not taking any action.  I'm posting for solidarity and to subscribe for any possible future updates.

Does running tpfc [ThinkPad Fan Control] make any difference?  I've been using one version or another of this since I started using ThinkPads, and it's made my life a lot quieter (I do look forward to a day when fans are unnecessary).  tpfc allows you to customize your fan's mode of operation, and has worked well for me on X120e, X140e, and X240 machines.  With tpfc running, my machine idles along at 60-65 with no fan running, and doesn't get too noisy unless I'm messing around with a lot of stuff.

 

Ummm, maybe never mind...weird

 

It looks like the site for tpfc is no longer available, which is unfortunate.  There are a number of other ThinkPad fan control softwares around, but I am the most familiar with this one...

Re: Lenovo X270 noisy fan

TPFanControl is now at https://sourceforge.net/projects/tp4xfancontrol/.  Yes, it does control the fan on my X270. But I am not going to use it permanently as I am not confident that it is not potentially damaging to the CPU as it allows it to run hot without the fan. I used it to test the system and prove that the fan does respond to control commands. Clearly the system could do this itself but is not due to either some configuration issue or conflict.

 

I find it interesting that lenovo acknowledged a fan problem with several newer generation machines like the X280 and T480 (https://support.lenovo.com/us/en/solutions/ht506625)

 

This issue happens because of an incorrect setting that was applied in the factory preload. The incorrect setting causes the processor to idle at max turbo speed, which may generate excess heat and cause the fan to turn on.

 That sounds suspiciously like an explanation for this issue on the X270 yet no "fix" has been provided for the older machines.

That sucks.  That must work the battery pretty hard as well.  Under those conditions, I might be tempted not to use TPFC; fortunately, it seems to work well with my (older) machine.

 

But I assume that the problem is somewhere it can be fixed (though preload of what?).   If not, then I think there's a good argument for replacing the machine...

Re:Lenovo X270 noisy fan

I've been having the same problem with my x270. Very noisy fan all the time and my battery would drain very quickly (maybe 4 hours of useage)

 

My original solution was to just not use the laptop, which worked well untill I needed it for a business trip.

 

After a lot googling, I came across a solution that seems to have worked for me. I changed the "Max Processor State" to 99% on both battery and mains mode. 

 

It's only been a day but as soon as I made the change, the fan switched off and when it does come back on, due to using lots of apps, it is very quiet.

 

Not had a chance to see what the battery life is like but im hopful it will increase as it seems the processor is no longer needing max cooling all the time.

Mine eventually died 1-2 months after the warranty expired. It can't be turned on either. I almost went crazy for noise for 3 years. The crapest laptop of my life. I didn't get any help from anyone on this forum. No solution, just the noise. ALWAYS. I never buy that. (The repair cost would be more than $ 500)

Yes, I have lowered the max processor state on all my windows PC's.  It seems anything below 100% helps reduce excessive fan usage.  This has helped on multiple Lenovo Thinkpads and also on several Lenovo and HP desktops.  At this point I am not sure if the root issue is a Lenovo firmware/hardware problem or with the Windows kernal.  Either way, I agree this power setting does help.  Unfortunately, I have noticed dramatically poorer performance with some CPU intensive apps like Adobe Lightroom and Photoshop when the max processor state is reduced.  The difference in performance seems far greater than the 5-10% I am reducing the power state by.

Seems that my original assumption that the fan issue was fixed by changing the Max Processor State to 99 was incorrect. After changing the setting back to 100 to see what would happen, the fan is still behaving correctly and the battery is not draining.

 

A few days before changing the Processor State to 99, I ran the Lenovo Vantage software and updated the bios as well as some other recommended items. The fan issue was still present after these updates. Just before changing the Max Processor State to 99, I restored default settings for the balanced plan, which increased the screen brightness (I must have been tweaking settings in the past to improve battery longevity). I then changed Processor State to 99 straight away.

 

Now I’m using the laptop on mains power, balanced battery at 100 Processor State and the fan is silent. The CPU is temp is 47c average with little load.
