Re: Lenovo y720 fan is too loud

During the initial boot, the fans usually rev up and then quiet down depending on the temperature.

 

Are the fans loud continuously, even after booting?

Can you check if Extreme Cooling is disabled in Nerve Sense?

 

If possible, can you make a audio/video of the issue?

Thanks.

Re: Lenovo y720 fan is too loud

If you are using the laptop in you lap/bed, without proper air circulation, the fans will try to kick up more. Use it on a desk and keep it propped up at the back as the intake vents are at the bottom rear.

 

Also, this is a gaming laptop so expecting a low noise environment is pointless. Usually the fans are going to stay between 35-45dB range. On high load, this can go up to 50-55dB.

 

This can be measured using any smartphone app, but remember that app needs a lot of calibration, a quiet room and measurement about 1 m away from the laptop.

While playing games, music videos I dont even hear the fans (and I am pretty senstive to sounds.)

Re: Lenovo y720 fan is too loud

Thanks for the video.

 

As far as I could pick up, the fan only went up when logging in/boot. There was no other instance of it revving up, or maybe the sound was not picked up. I am listening my headphones with full volume.

 

If that is the case then I would say that is totally normal and you will not find any model that does not do that.

 

BTW, which keyboard are you using, sounds like Cherry MX red switches.

Re: Lenovo y720 fan is too loud

That keyboard sounds beautiful. (I am listening to your video just to hear the click clack) I think I might go for blue switches next time, but brown ones are usually cheaper Smiley Tongue (I have Kailh Red right now)

 

As for the fan sound issue, I think that is normal so I cannot say anything more.

Re: Lenovo y720 fan is too loud

I ended up here as - after a month of being great - my Legion Y720 fans were suddenly on "full" mode. There was no significant CPU activity leading up to this. The fans are normally *very* quiet, by the way. Also, I have my laptop on a metal "mesh" holder from Amazon, so underneath cooling is never a problem.

 

My solution was to reboot, and now it is normal again. I post this here for three reasons:

1. Something went wiggy, and I want Lenovo to be aware of it,

2. The "solution" given in this thread is no solution at all. 

3. I want anyone coming here to realize that the Y720 fan noise is normally very quiet (I am also sensitive to noise).

 

And IMHO, keyboards are also supposed to make the least amount of noise  Smiley Happy  (I use the Logitech K800)

 

Hopefully, this won't re-occur, as it really freaked me out.

Re: Lenovo y720 fan is too loud

I can confirm that this problem is reproducible and it started happening after I updated my windows to ver 1709 about 4 days ago. I had held off of that update for a while now.

 

Is your windows on v1709?

 

I will try to modify some settings over the weekend and see if that quietens the fans. Thanks.
