Something at 128*C???

[mojothehut]

Hey all,
So I recently replaced a hd on a two year old system. Reinstalled everything, things are peachy. Just installed HWMointor to check out my temps and noticed something new (that wasnt there in my last build)
I'm getting a temp read out of 128C on what I dont know. But the temp never changes.

I've uninstalled HWMonitor and reinstalled it, same thing. Last week on my old hd that temp was not there.. So only thing that has changed is 1. hd. 2. fresh win7 pro install.
I'm on an Asus sabertooth 990fx with an AMD 975@4.0. I've had the cpu overclocked and stable now for two years...

Anyway here is a picture of the strange temp.
Any idea what it could be? Or just some strange glitch?

Looks like everyone is having the same thing. Its just misreporting a non-existent temp. Some people say its NB, some say its VRM's.............neither of which are at 128C, I assure you.

Hardware monitors aren't perfect due to the number of devices they have to support. This causes an irregularity in reading that may be caused by the BIOS revision itself or the hardware monitor isn't the version that has proper support for your particular combination(CPU + motherboard). Its better to decide on what's the most accurate reading by double checking with multiple hardware monitors.

Its without a doubt that 128C falls within this anomaly as CPUs tend to have thermal throttling at 100C(governed by its specified TJmax), and much lower for a Phenom 2.

Here's one of the anomalies that I had when OHM doesn't have support for an IB(since I tested it before IB's official release).

I actually called MSI about this phantom temp since it was concerning me during overclocking and no one seemed able to provide hard information on it. The tech support guy I spoke to assured me that MSI boards only have northbridge (TMPIN2) and CPU socket (TMPIN0) diodes and that HWMonitor's TMPIN1 (AUX in HWInfo) is a false reading based on behind-the-scenes algorithms.

It seems to scale linearly with voltage increases and CPU load percentages, so my guess is that it's some kind of calculated VRM temperature. However, one day I got brave and touched my VRM heatsinks after an hour of OCCT. TMPIN1 showed 67C (you'll get burned at around 50C), but the heatsinks were barely warm. Because of this, I feel confident saying the temp is bogus.

It may be different on your board, but since it seems anomalous and your socket/NB temps are already accounted for I'd guess it's the same story. I've also heard stories of that temp showing 128C constantly as you are experiencing or even 256C (!!!). Rest assured that if something was actually running at that temperature you'd be having... serious issues.

Just ignore it, my friend.
