Ideapad 710s-13IKB CPU too eager to turbo clock, has erratic fan control

2017-02-02, 2:26 AM

Hi, I've read about some issue with yoga 710 fan noise that was recently fixed with a BIOS update. Is there an update for ideapad 710s-13IKB on the way? The unofficial third-party fan controller software doesn't work, perhaps because this laptop has two fans.

 

Just installing some software for example causes the i5-7200u CPU to overclock to over 3GHz  which seems unnecessary. Limiting the CPU max clock to 70% from power management settings helps but is an ugly fix because it's a constant limit. When the temperature is +40C the left side fan stays on.... +39 and below the fan seems to shut down, but doesn't happen unless I let the computer idle for a long time. The fan control seems to jump every 10 degrees. +70C and above is the highest level. Because of the over-eager turbo clock the laptop can reach +70C very quickly and go into full fan power when doing low-intensity tasks. It does this every time I power on, and it takes a minute to lower the clock and fans down to reasonable levels. I noticed the fan issue straight away when I installed the W10 anniversary update. CPU/fan issue could be linked to high hard drive activity also.

 

Also, the Lenovo Battery Gauge doesn't appear no matter how many times I try to enable it. It just doesn't want to show up on the task bar. Is it a seperate issue or are these two related?

Well after learning to use the third-party program (set to the 500s profile) it's a non-isssue for me now. Performance is great with the standard power plan. As a general comment I love the hardware, but if Lenovo doesn't customize the fan profiles for each model they should provide us a program that lets us modify them. This can really drive away some people.

 

I'll make a seperate thread about the battery gauge if it doesn't appear soon.

With my Lenovo 710S-13IKB the 500S config works! But NFBC keeps shutting down. I always have to restart it. What could be the problem there? And is it no problem for my Laptop to use another config (like the 500s one)?
