Lenovo always has this problem. But it is partially fruit of a wrong regulation decision of Linux. I do have much of ventilator reserve but under Linux the vent is not going to speed up over a certain limit. That is quite absurd, but the difference between high and max is huge. But linux seem to give signal only for high, not for max. When having a hanging process, this causes in my laptop regular shutdowns (that is why 15.2 is not usable for me). I do not think this will be different in your case - although this is a powerful and otherwise well designed machine. Look in the BIOS to see if there is a setting. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I don't see a problem, just a design decision. Yesterday the fan was spinning at 4200, not it seems to go at zero. I will try again later today and watch the fan. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

yes, and reducing the cpu speed is the best solution I found. cpupower frequency-set -u 2.6G (2.6 for my config, this simply forgive overclocking) specially if the target is that slow, no reason to go fast and for day to day use, not speed difference visible jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

People open their wallets wider for faster and smaller and quieter. But all of those qualities (and some others) crash into physics, so there must be "throttling"... which isn't advertised so much. What the Advertising giveth, the Physics taketh away. :) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
