Comment 20 for bug 1600599

I agree with your reasoning teo, I was just mentioning that it didn't apply in my situation since I know my fans are at the max all the time. But what you're saying is true - thermald does reduce performance before I get near the max temp (as reported by 'sensors' high=80 and crit=98), sometimes by a lot, and sometimes it fails to increase the performance again after the CPU has cooled down (I just reproduced and will attach separately).

Perhaps it's just that the thermald default configuration is too conservative, and is kicking in when temp is within 10C of 'high' but not 'crit' (which seems more a better choice). I may try to change the settings mentioned above (what is the difference between SetUserPassiveTemperature and SetUserMaxTemperature?).
