Is there a temperature sensor on Pine?

Thanks longsleep, your post is very very interesting. I did not think that 45°C could be a normal temperature

A heatsink greatly improves heat dissipation for normal short burst work loads or in bad thermal environments (eg. inside a case with no air flow). Without a fan, the heat sink will reach its maximum dissipation capability after a couple of minutes of constant load  (the exact time depends on the heat sink quality, ambient temperature and air flow).

So, do you think heatsink is a good buy?
