Re: Yoga 910 crazy loud fan even when CPU at <35%

I can officially confirm this is a genuine problem with this model.

 

I bought a 2nd one from Best Buy. Exact same issue!

 

It seriously is so loud when doing anything intensive

Re: Yoga 910 crazy loud fan even when CPU at <35%

I am running the laptop for a week now, average usage > 8 hours per day. I have the same feeling in the first 3 days, was pretty annoyed by the fan. However after it settles down with all the initial windows updates as well as setting the maximum CPU to 99% (I can still use the high-performance profile if I want the little missing CPU frequency), it has been really quiet for the last 3 days. Also I switched to Edge instead of chrome. As of now, I am pretty safistied.

I agree the 99% change makes a difference. Its more manageable

and agree Edge is massively better than Chrome. No questions

Re: Yoga 910 crazy loud fan even when CPU at <35%

This is a known issue and is all over the Internet. There is no formal solution from Lenovo although the following solutions makes a massive difference.

I have taken the extreme approach of 1. Ordering multiple units 2. Unscrewing the units to determine the root cause

I can confirm that the following problems occur:

1. The physical fans themselves make a high pitched whine when operating. The level of this noise depends on how fast they spin
2. If the processor hits 100% CPU usage the fan spins at max and sounds extremely loud
3. Many background tasks on Windows can momentarily cause 100% CPU usage


Here are 2 solutions you can easily do that helps a lot:

1. Set Maximum Processor State to 99% in Power Plan settings so the fans never hit max
2. Only use Microsoft Edge. It requires far less processing than Chrome

If you do this the laptop noise is manageable.


Lastly, you can open up the laptop and unplug both fans. The laptop actually runs surprisingly cool, so this works. As a precaution you must do the following:

1) Set Max Processor State to 80%, which will keep the computer cool
2) Install HWInfo and add the CPU temperatures to the task bar so you can monitor them. If it hits anything consistently above 70 degrees, i'd plug the fans back in as your use case is too processor intensive.

If you do the above... your laptop will be dead silent

I am returning my unit back to BestBuy. I did not pay $1600 to limit my CPU or be forced to use Edge or unplug fans. Even with CPU limiting still hear too much noise. So sad one big flaw ruined such a beautiful device.

Totally agree re returning. Just make sure to post a review on BestBuy so Lenovo sees it. They will only fix it if it hits their wallet.

 

The problem I have is what else will you buy? There is nothing better:

 

* Razers have dreadful coil whine

* Dell XPS has coil whine and get very hot

* HP Spectre and Acer do not have a retina display in their comparable models (although the HP has some good reviews)

* Alienware 13 weighs 5 pounds

* Samsung Ativ 9 Spin has 2 hours of battery life and gets hot

* Apple Macbook Pros have an awful keyboard, last years CPUs and are insanely expensive e.g. $2,2K for a comparable model

 

 

Interested to know what you go with

Re: Yoga 910 crazy loud fan even when CPU at <35%

What a great machine. I truly enjoyed using it for the few hours I kept it. The noisy buzzing fan was a show stopper for me. I have owned more than 10 notebooks and I do not remember one that has such a loud buzzing noise. I do not mind the 'typical' humming sound of fans e.g. surface pro, but this one is truly annoying.

 

Seriously, why should we accept such noise as a 'normal' cost or by-product of using a computer. It does not have to. Lenovo exceeded expectations in so many departments engineering this machine, but why'd they ignore the fan noise. 

 

Thank you Lenovo for making such beautiful machines. 

 

Thanks

Re: Yoga 910 crazy loud fan even when CPU at <35%

My fan noise is randomly and short but seems reasonable, caz from task manager, windows update or storage scanning or edge/ie happens when noisy. Maybe my scenario is already noisy indeed that i do not care so much ...
