[smartmontools-support] Time in Over-Temperature seems to be incorrect

OK, I see where you see the 41. I happen to have the same model (Crucial MX
500 1TB) laying around here, so I quickly plugged it in to see if I see
something similar. And indeed:

0x05  =====  =               =  ===  == Temperature Statistics (rev 1) ==
0x05  0x008  1              31  ---  Current Temperature
0x05  0x010  1              50  ---  Average Short Term Temperature
0x05  0x018  1              50  ---  Average Long Term Temperature
0x05  0x020  1              60  ---  Highest Temperature
0x05  0x028  1               0  ---  Lowest Temperature
0x05  0x030  1              51  ---  Highest Average Short Term Temperature
0x05  0x038  1               0  ---  Lowest Average Short Term Temperature
0x05  0x040  1              51  ---  Highest Average Long Term Temperature
0x05  0x048  1               0  ---  Lowest Average Long Term Temperature
0x05  0x050  4              50  ---  Time in Over-Temperature
0x05  0x058  1              70  ---  Specified Maximum Operating Temperature
0x05  0x060  4               0  ---  Time in Under-Temperature
0x05  0x068  1               0  ---  Specified Minimum Operating Temperature

As in your case, the highest temperature was never above the "specified
maximum operating temperature". Yet 0x05:0x050 (Time in Over-Temperature)
shows a value of 50 (41 in your case).
I suspect this to be a false information from the drive or a false
interpretation of the drive's data by smartctl. @Christian maybe you can
spot this immediately?
