Re: Ideapad 720S-14IKB fan noise/cycling

I really appreciate an official answer to this post finally (it is the first and only one AFAIK). The proposed alternative is really sad as it does limit single thread performance though. We need a proper solution for this.

 

Was this escaled to the technical teams? Will they fix it?

Hope Lenovo can fix these problems!

 

When I returned the product, I could not find a satisfying alternative to Ideapad 720s with such a premium body and very well-designed laptop.  I ended up with Thinkpad T480s, yet still sacrificed a few things even though it is much more expensive.

 

The problem is the fan is that it ramp up too quickly, it's like it has 2 steps, run at 20% then 100%

20% fan speed is perfect, but when the temperature is around 55 degree celsius, it went up to almost 100%, I think, with a few adjustment, Lenovo should be able to run the fan around, say, 50% so that the sound is not too bad, and the temperature remains acceptable.

Essentially the same behavior as in my 520s.

Hi,

 

I have also the same fan noise problem with my Ideapad 720S-14IKB as others have. 

 

This suddenly accelerating fan noise up to max is very very irritating as it happens in very basic use of computer (like reading your e-mails etc).

 

As a customer I think decreasing CPU performance can't be the final solution / advice of supplier to this issue.

Doing a clean install of Windows 10 has helped the excessive fan noise quite a bit.

Hello, I am also having this problem. When I got my ideapad 720s 14 in early August, I went through a very difficult series of customer support phone calls during which the tech did a BIOS update. This helped for a while, but now the fan is going back to very loud noise, as everyone explains on this board. I have the same feeling as most people, I LOVE this computer and would highly recommend if they they could fix this silly fan issue! PLEASE! I went back to see if there was another BIOS update, but the most recent one I could find was for mid-August 2018, which I already have. I really hope this is fixed soon.

Wow...  So this laptop has recently been on sale here in the UK.  I read some complaints online about the fan noise and scoffed a bit before I purchased - I'm used to fan noise, hell I love fan noise...

 

Now I feel like a complete fool - this fan is so whiny and constantly up and down - it's like having the worlds worst theremin player giving you a constant and dreadful private session.  The first thing my wife said to me when she got home tonight was "it's making a strange noise!"

 

How on Earth has this passed QA?  How can we be 10 months past release with no attempt at a BIOS fix to at least prevent the fan speed from constantly ramping up and dropping?  Why is it 40 deg C when it starts to whine like a banshee?

 

This is otherwise such an awesome laptop.
