C2050: temperature and ECC errors

What says (about temperature and hardware errors) following nvidia-smi report ?
Is the temperature value inappropriate high (and why in this case FAN speed is only 30%) ? Does the number of ECC errors says that there is serious hardware problems w/C2050 ?

BTW, the System temp of mobo according lm-sensors is about 46 C, what looks OK.
