Yoga 710 - Constant Fan Noise even when idle

2016-06-21, 8:57 AM

Last week I received a brand new Lenovo Yoga 710. The internal fan produces a constant noise i.e. it is constantly running. Of course the fan/noise increases with CPU load but it never stops when the CPU idles (e.g. regular Office work).

 

I checked with Windows Task Manager, that there is no background load that could produce CPU, Memory or Disk activity. Ambient temperatures are normal (22 degrees C), machine is on the desk and cool.

 

Is there a BIOS upgrade or setting available that fixes this?

 

Fred.

 

P.S. Machine type info 80TY000SGE (Core i5, 8 GB, 128 GB SSD, Intel GPU), Windows 10 original installation.

Solved! See the solution

Hi there, Fred -


Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

I have fixed the issue with the fan by installing TPFanControl or later version to check the temperature and change the fan to SMART, instead of BIOS.

 

By the way, what version of BIOS are you running?

 

Update us how it goes.

 

 

 

 

Regards,

THank you for your Support. 

 

I'm running the original BIOS version that came with the computer and is according to the support site also the latest version:

I also tried TPFancontrol but couldn't get it to work. Apparently I would need a profile for this model. 

 

Fred. 

 

P.S.  It's a shame since the Yoga 710 is a great notebook - only the noise makes me mad.

I’ m sorry that your issue have not yet fixed.

 

Launch Task Manager, switch to the processes tab, make sure you are seeing processes from all users and sort on the CPU column. Wait until the system goes to an idle state again. You will probably see at least one process (besides the System Idle Process) rise to the top of the list (most likely an anti-virus or anti-malware program scanning the system while you aren’t actively using it).

When more CPU cycles are being consumed by a process other than the System Idle Process, it will generate more heat and the fan will need to spin faster to dissipate the heat. If this process is not necessary, disabling it will stop (or reduce) the speed-up of the fan and thus reduce the noise.

 

Also, this might be a malware. Run a full scan with a good anti-malware program like Malwarebytes.

 

Update us how it goes.

This was exactly my first thought: any background activity that consumes CPU.

 

But I can guarantee, there is none.

 

The system uses the out-of-the-box image with nothing installed. No load. Real idle. No luck.

 

Fan is spinning (low). As soon as you start something easy e.g. Internet Explorer and start surfing, tha fan speed increases. If you increase the load, the fan increases speed immediately.

 

And this is no normal behaviour: regular Office activities at normal temperatures should not cause the fan to spin.

 

Fred.

I received the Yoga 710 few day ago, great hybrid, nice look and fast.
The only drawback for me is the fan noise. I'm searching a software for fan speed but i haven't found anything yet.
I try Hwinfo64 for temp monitoring (Tcore) and here are my results:
Hwinfo didn't find any fan speed but it appears that fan make no noise when cpu is ~35°C.
~40°C to 45°C fan is loud with hi frequency sound
>50°C i guess fan is at max speed, very loud.

I checked intel i5-6200U cpu and as you can see here : http://ark.intel.com/products/88193/Intel-Core-i5-6200U-Processor-3M-Cache-up-to-2_80-GHz
this cpu has 100°C Tjunction so did we really need high speed fan @40°C ?

I would like a more linear fan speed instead of (in my opinion) a low medium high speed but maybe i'm wrong.

Sorry for my english.

I have this problem too.  I think it will end a bios upgrade.
