This temperature seems to be "normal" currently. Given environment
temperature is above 30 degrees, so I'd guess this not too high for a
laptop (as there's not much space in the case).
However, using some graphics, temperature arises even above 80 degrees,
that's much too high, so I'd expect the fan to rise speed, but the
amount is too few, cooling is not really successful.
As I'm neither a hardware nor a linux expert, I'd need some support to
find out what happens. First, I'd like to get some info about fan speed
- "sensors -u" is not sufficient.
