Haha ok I know what I'm reading tonight then Thank's for the quick and great replies, much appreciated

Awesome, thanks Yeah I totally confused the ambient with the internal temperature... my bad. I'm not actually going to mess with any of Armbian's defaults, the only thing I'm trying to balance is when my little 5v fan starts spinning in my 3D printed case I have a daemon monitoring the cpu internal temperature that controls when the fan starts (and making noise in my living room). Am I understanding the the issue you linked correctly that the first core is shut down at 75° ?

Hi all, I was just wondering if you had experience with the performance on the H3 allwinner CPU performance based on the cpu temperature ? I'm trying to tweak my fan to only cool down the CPU once it gets close to peak cpu temperature levels, before performance starts to degrade. According to the Allwinner H3 datasheet the maximum ambient operating temperature is 70° (see page 612) http://dl.linux-sunxi.org/H3/Allwinner_H3_Datasheet_V1.0.pdf Do you think I can let the cpu go up to 70 before cooling it down or should I start sooner (i.e 65° / 67°) to keep my pi at top performance ?
