TMPIN2 is a dead sensor, it's on the chip but not connected to anything. This is why you get the strange readouts.
That's good to know and it makes sense. Just built a new system and I have the exact
same reading on TMPIN2, 128C. Everything else is mid 30sC (hard drive 25C).
The build has been fast and rock-solid from the get-go...POSTed 1st time. Win7 Home Premium 64-bit installed perfectly.
