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

I have   720S-14IK also . 

 

The fun noise just makes this laptop useless, I keep it  limited  to  98 %  all the time  otherwise I cannot stand this unregular fan work .

 

Spending the  money for someting you can use in a half , reather not a good deal ..................

Have disabled Lenovo App Explorer and with updated (Mar 18) BIOS plus default power options - the noise issue is no longer.

I have the Ideapad 720S 15" i7-7700HQ, 1 TB SSD. I have a fan problem as well: Here are the sound files (turn up sound)

The first one is just internet browsing and the second one is playing the sims 3.

Anytime the fans starts to get a little high I hear that strange buzzing noise. The fans just seem to always be running even on basic tasks. The problem becomes less noticable when I do the fix of modifying the processor state to 98% Is anyone else hearing this noise?

Hi All,

By default, laptop power plan is High Performance. Change it to balanced mode and check.

I tried and this helps to reduce the fan noise.

Regards, Vikas

Hi everyone,

 

I got the 720S last week and the fan noise was present out of the box, even in almost under no load, and I was thinking of returning it back.

 

But, after I got the BIOS updated, the laptop got very quiet. It keeps quiet and the fan starts to become noticeable for shorter periods of time only after 6 hours of my regular use.

 

I do use the laptop for mostly browsing in the internet and in office documents (10+ tabs in the browser - some with 720p videos, a few PDF files and Word documents).

 

I have to mention that at the times fan kicks in, the way it sounds is not very stable. It is on and off on higher frequencies.

 

I wanted to inform those who have not tried updating the BIOS; and also to consult to you if my experience of a quiet laptop is due to my using habits or not, if it is still a problemmatic laptop I will return it for my future concerns.

@barbar1

 

What version of the BIOS did you update to? Also, what gen is your cpu?

 

I too recently purchased this laptop and updated the BIOS based on feedback from tech support. However, I got no relief from the fan noise. I have the 8th generation i5.
