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

How about to disconnect one fan on the motherboard? There is little connectors. Should be less noise.

The fan issue is really annoying, and i hope they will fix it sooner rather then later. But I have a problem with the performance. Comparing cinebench 15 results, an Asus PC with the same specifications scores 641 points on all cores, but my 720s-14ikb only scores 385 points. That's a big difference, and it's actually much closer to the i3 processor in performance. It's too bad in my opinion, probably will not buy a Lenovo product again ...

Hi guys,

the fix is mentioned already in one of the posts above.A week ago bought Lenovo Ideapad 720s i7 and had the same issue since.Even after all Windows and Bios updates we done,fan was still going like crazy.Only after reducing 'maximum processor state to 98%' laptop got silent right away.That turns turbo boost off,though laptop still perform fast.It is not ideal,but still worth to give it a go and see for yourself.Power Option>additional power settings>change plan settings>change advanced power settings>processor power management>maximum processor state....By default that is set to 100%.Double click on it and set to 98%,apply and enjoy the silence:)
