It always return 40,0C regardless of the value I get from other sysctls:

If you are really brave (and please, keep in mind that messing with your
ASL just might toast you piece of hardware), you can try [really
hackish] patch below. It would not solve problems with the passive
cooling (at least not by itself), but might provide you with meaningful
temperature readout. Unfortunately, I have no idea what condition BIOS
writer was checking to decide whether to give you results of reading of
some sensors or just 40C flat out (0x0C3C), so you might trade your
condition for some random value having no bearing on the reality. Given
the fact that that code path converts value to the tenths of Kelvin
twice, I would not be overly hopeful.
