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

2018-07-26, 12:52 PM

I managed to build a partial config for NBFC (notebook fan control) for the 520s-14 (see https://github.com/hirschmann/nbfc/issues/521), that might work for the 720s-14 (I assume it has a single fan as well).

 

Unfortunatelly I couldn't find the register/value to configure the EC to allow manual fan control (otherwise NBFC and EC keep overwriting each other).

I just got mine today, the spec is i7 8G 256G, and I've update the BIOS to the latest version. That fan noise irrates me immediately, especially when it's completely idle. Would lenovo update the BIOS to fix this problem, Or I am considering returning it.:smileysad:

lbgguy: Do yourself a favor and return it immediately.

Lenovo already released a refreshed version of these laptops {3,5,7}30 and is yet to post a single response to these fan issue threads.

I'd say there's little to no chance of they fixing this at this point.

Yesterday I found a super fan control program https://github.com/hirschmann/nbfc
Just install and use the Lenovo 710s profile.

Now I am fully satisfied with the Lenovo notebook.
I am sorry for my English.

Where is the Ideapad 730 available? I'm in need of a new laptop in the US and was eyeing the 720s but this thread basically killed my interest in it.

Ah, alright. It looks like the 530 with the MX150 is up around $1100.
