No.....well, not exactly.
AMD measure things slightly different, measuring more of a safe zone.
It maxes at 70'C, so in theory, you're 70'C - 37'C = 33'C. In practice though, the temp readings come from a different area of the chip and I believe there's a bit of a 'buffer'.
Your CPU is probably truly in the ~55'C range if you wanted to compare (somewhat) directly to Intels way of measuring, but with the way AMD monitor, you'll never know for sure, as TM is the only accurate method.
How does your TM look after "a while" of playing? Unless it's near 10'C or less, it's unlikely to be thermal throttling.
