About a week ago, just finished building this computer with a lot of input from everyone here - THANKS!! :thumbsup:

My general Stats for this question:
Mainboard Vendor ECS
Mainboard Model A790GXM-AD3
Windows xp home

I have run both SpeedFan and CPUID HWMonitor and both confirm all my hardware, fans and voltages are good EXCEPT what is in bold:

Voltage sensor 0 1.31 Volts [0x52] (CPU VCORE)
Voltage sensor 1 3.50 Volts [0xDB] (VIN1)
Voltage sensor 2 1.57 Volts [0x62] (+3.3V)
Voltage sensor 3 5.03 Volts [0xBB] (+5V)
Voltage sensor 4 4.86 Volts [0x4C] (+12V)
Voltage sensor 5 -9.92 Volts [0x9B] (-12V)
Voltage sensor 6 -10.05 Volts [0x9D] (-5V)
Voltage sensor 7 5.51 Volts [0xCD] (+5V VCCH)
Voltage sensor 8 3.07 Volts [0xC0] (VBAT)
Temperature sensor 0 31C (87F) [0x1F] (TMPIN0)
Temperature sensor 1 33C (91F) [0x21] (TMPIN1)
Temperature sensor 2 126C (258F) [0x7E] (TMPIN2)
Fan sensor 0 1923 RPM [0x15F] (FANIN0)
Fan sensor 1 2039 RPM [0x14B] (FANIN1)
Fan sensor 2 311 RPM [0x21F] (FANIN2)


I have done the following:
Turned the computer COMPLETELY off ( unplugged) for an hour
Turned computer on, it boots up real quick within 20-30 sec, immediately ran the program and was getting temps around 240F (!). - above the temp for boiling water!

Can anyone determine what this sensor is reading, says TMPIN2 -if that is a chip can it really withstand a temp of 250F+?!
Maybe the sensor is off...

I opened the side of the case, fanned air into it, did not change the temp, but made it bounce up and back - "up" meaning it went up a degree or 2 while I fanned it.

Any thoughts?

Thanks

Matt

If you're not having issues with your computer, I'd say it's probably misreading. I'm not sure of what that's reading either

A program that might help you; EVEREST Home Edition. It will give you all the information of your system. For temperatures just tick the + next to Computer and then tick Sensor. My cpu is 41 deg C /106 deg F. now. This program will give you more information about your system than you ever wanted to know.

According to HD Tune SMART data, my SSD is at approx. 2.5 million degress right now. I thought it was a little warm in this room.

In general, silicon devices are rated for 100 degrees C or less. If it actually was hotter, you would have noticed odd behaviour from the hardware.

Generally speaking...any 3d-party utility which provides temperature data to users...seems to always have a disclaimer (which users don't bother to read) stating that the accuracy of data depicted is not guaranteed by the developer of the utility.

I would go to ECS and see if they have a temperature software of their own. sometimes the manufacturer software takes more accurate readings then third party. But I would definetly use another utility, third party or manufacturer, and if that reads high to, go from there.

I've noticed Speedfan to be a little off too.
However, it's very possible it's the sensor.
