My Northbridge runs at 128C idle...

CPUID reports the TMPIN2 (which I'm guessing is the northbridge temperature) to be 128C on my Asus M4A785TD-V EVO while idle. All other temps are within acceptable range. Is this a faulty sensor reading or is my northbridge really going up in flames?

Can you post a pic of your CPUID?

My guess is that it is either a faulty sensor or it isn't truly reading anything, so there shouldn't be anything to worry about. If you system is not crashing, I would venture to say it is not truly reading anything.

As you can see all the other temps are perfectly normal except for the ridiculous TMPIN2 reading.

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.

I also get 128C on my northbridge. But I also touch both heatsinks and I can't keep my finger on it for very long. Its very hot. Also my internet cuts in and out. I feel that this is a bad motherboard and all Asus M5A97 models have this issue or it's the FX-83XX series that do this. I had a FX-8120 and my n/s bridges never got that hot. Any ideas. Thoughts? Im trying a gigabyte GA-970A-D3P and if that does the same thing then I know its the CPU.
