Yeah, its reading in fahrenhiet. 127C and your mobo would be like, non-existent! Also, thingss like your CPU, RAM, video card, SATA/IDE cables would be melting. But 127 F is fine.

Looks like it has your Motherboard Temp/Northbridge. and the Power/Aux Temp. backward. The Power/Aux is for your P/S that most P/S dont have so it gives out wild readings. It has your 12V reading wrong to. It would not even boot with only 4.91V on the 12V line.
