What are these temps? 127*C?

One of your bridges maybe.

TMPIN2 is a "dead" sensor. It's on the chip, but isn't connected to anything. That's why the strange readings. Don't care about it, you're fine.

Wouldn't it shut down if it were really taht hot?

The sensor seems to be functioning. Right now it is ~64*C.

But it ain't..TMPIN2 gives wrong readings cause it's not connected, so it can show "normal" temps or extreme temps at random times..
shows expected idle temps, or extreme temps.. non of them are right, you can just ignore the readings.

Just try Googeling it as well, and you'll get loads of hits from people reporting the same issue...

That used to happen on my 9950 and A79A-S its normal. If you check AOD there will be a bogus temp also.

HWMonitor gives out some funky readings sometimes it said one time my cpu fan was running @ 80,000 RPM's and my 12v @ 1.2v and its read my core temps as high as 150C. Its just a buggy program with certain motherboards

You're ok man.. anything at that temp would have been gone by now anyway, so just like the others have said, its HWmonitor playing tricks on you with some wrong readings.
