HWMonitor TMPIN1 temperature abnormally high

Hi,

I booted my PC up today and did the usual temp check to make sure everything was okay and I noticed HWMonitor reporting the TMPIN1 temperature as being 127C, although my CPU core temps were only 25C.

I found on another thread on here that the TMPIN1 points to the CPU, or more specifically, the north bridge temperature. I was tinkering the other night with the CPU/NB voltage in an attempt to overclock my CPU further, although it was short lived as I found no positive results. I stopped once I hit a CPU/NB voltage of 1.21V

So with that in mind, I did a CMOS reset to clear all every setting possible and proceeded to boot up into windows and immediately turned every fan on full. The results are shown below:

Is it possible I have damaged the northbridge on my motherboard? Should I be worried or is this just an anomaly? Hardware specs of PC below:

Case: NZXT Phantom 410
Motherboard: MSI 990FXA-GD80
CPU: AMD Phenom II X4 965BE @ 4.1GHz
CPU Heatsink: Cooler Master TPC-800 w/ 2x Corsair SP120mm fans
RAM: Avexir White Core Series 8GB (2x4GB) @ 1600MHz
GPU: MSI GTX660 TFIII
HD: Kingston HyperX 3K 120GB SSD + WD Blue Series 1TB HDD
PSU: Corsair GS600 (a Cooler Master V850 is on its way!)

PS: It should be noted a full 3 hour Prime95 test has been carried out on the CPU at 4.1GHz prior to the CPU/NB voltage change, so it was fully stable.

I usually just click down HWMonitor and open it again and it is all fine, try it!
Core temp and different stresstesting programs usually give you a temp. try it out, most certain it's a miss reading, which CPU would survive that?
Try closing HWMonitor and open again, it'll start a new calculation!
I play games and render stuff at like 55C and that makes 255C totally out of range!


Thanks for the reply, it's reassuring to know it's not just me it's happening to! Are you sure it's just an incorrect reading? I get freaked out by things like this as I like to keep the temps pretty low and I don't want to be forking out cash for a new mobo. I've just spent it all on an MSI GTX770 Lightning + Cooler Master V850 PSU.

Is there another way to check the TMPIN1 temperature using a different program? I want to believe it's just HWMonitor, but I want to be absolutely certain.

Many thanks, I was getting worried and ready to RMA my board as I did feel the Northbridge getting quite warm to the touch. I read on another forum though that it might be a contact issue and to put a bit of pressure on the heatsink and I believe that helped. It still gets warm to the touch, but nothing like what it was reporting on HWMonitor.

What really convinced me it was a software bug was when I noticed that the TMPIN1 field had disspeared from HWMonitor altogether. Only TMPIN0 and TMPIN2 show up now. As I thought more about it, when I first built the PC a few months back I never once saw a TMPIN1 field within HWMonitor so it just appeared out of nowhere this one time just to scare me lol.

Either way, I've been using my PC ever since I noticed this and even been gaming too, nothing has shut down or BSOD'd on me so I can confirm it's safe.

Thanks for your help & reassurance :)
 


No worries man! Glad to help! :)
