Broken Temp Sensor or broken program? Or both?

Well, I was chillin, watching some anime on my laptop, left the room for a good 40 mins, then I came back to this ( I arranged it for the SS )



The first thing youll probably notice in HWMonitor is the 125C recorded temp for my GPU. Yes 125C. The second thing is the lowest temp for the HDD which was recorded at 0C.

So this would draw me to to the conclusion that my temperature sensors were broken, however, Ive also recorded temps at 111C and 115C, not to mention the times I didnt have HWMonitor open while I was gaming. This is the first time Ive seen a temp at 0C like that; the ambient temp isnt nearly that cold ( a bit warmer than room temp ), which is what draws me to think something is malfunctioning. Also, im now running GPU-Z along with its temp logging to use a cross.

Any thoughts or opinions on this?

Edit : That looks like crap, ill try to repost a clearer version

 

Sometimes software doesn't always pull temp readings that would correlate to actual temperature; it's a recognized phenomenon. This can be due to sensor probes being off (they're not a calibrated thermometer, after all), or the coding interface with the sensor introducing a variable multiplier into the temperature calculations. Plus, the temps you're getting would likely either start melting plastic in the immediate area or come close to triggering automatic downthrottle/shutdown protocols built into the BIOS.

The single qualifier to my analysis is how you were using the notebook when the temps were recorded -- was the notebook sitting on an open hard-surface desk, or sitting on a comforter in bed with all the vents blocked?

 

I had an old P4 Asus desktop board years ago that used to record temperatures of between -128c and 256c over the course of the day.

I learned to take temperature readings with a pinch of salt. :x

 

It was on my lap on top of a shelf board ( i took it off of a shelf and use it to protect myself from the heat ). Also, my laptop does frequently shutdown, Ive already opened and cleaned out the dust but it still gets hot. Ive already issued an RMA and plan on sending it out over christmas break. Also, the auto-shutdown is very random; like, ive seen it hit 101C and shutdown, and then 115C and not shutdown ( temps in hwmonitor ).

 

That is weird, the temperature sensors may be malfunctioning. Do you feel the notebook physically getting hot?

Also where did you clean the dust from? Typically where it gathers is between the fan and the heat radiator ("fins").

If the computer does indeed get that hot I would a) check that the fan(s) are indeed running and b) try reseating the heatsinks and changing the thermal paste (unless it's still under warranty; in which case I would send it in to ASUS so that they do it -- heatsink removal by yourself would void the warranty).
