I have a Giga-Byte GA 7n400 Pro 2 Motherboard. When I configured MBM5 to show the third thermal sensor (named: ITE8712F-3) it came up with a temp of 74 degrees. does anyone know what this sensor is monitoring, and if so, is that temperature likely correct. A full description of my system is in my profile. curren cpu/case temps are 47/32.

According to MBM's site, that sensor is your CPU diode.

Does it have only one output, or is the sensor listed twice, once just as ITE8712F-3 and again with diode behind it? If so, try the diode reading, and see what it reports.

...and cross you fingers that its current reading is not accurate. :lol:

a XP 2500 o/c'd to 3200 at high voltages in a stock Sonata setup (meaning no mods) with 5V fans and two (or is that three) harddisks COULD get you 74C.

With a hot CPU like that and so many harddisks, you'd have to mod the Sonata heavily to get lower temps.

Rusty: it also has a -diode reading, which upon trying gives a reading of -79 degrees. However by default MBM lists ITE8712F-2 as the CPU temperature. When i switch to ITE8712F-2 Diode it drops about 3 degrees.

burcakb: MY sig isnt exactly accurate. The CPU fan isnt at 5V, and the two case fans are running off of the FAN only connector on the PSU, so if the temps were too high they should ramp up. Also it is a 2500 mobile so it starts off cooler (30 watts lower output).

i just realized that it might be the northbridge chip heat sensor. If so, is the temp i was getting too high.

if that is in celsius and that is ur northbridge.. lol.. u'd being experiencing many problems.. notwithstanding that u might lose a MB. if that is ur case temp then ur in for shortened lifespan.. wat i would do is to cool ur computer or have it open and see if that temp changes. btw.. can describe in more details.. like is the air coming out ur computer hot? is ur heatsink on CPU situated right? does ur heatsink feel hot? does ur northbridge feel hot.. find the diode on ur motherboard.. remember to get rid of static first...

74° is actually an ok temperature for a NB. Warm, but not dangerously so. NB's are generally rated to run at up to 99°.

How much, and how quickly, does that reading fluctuate when going from idle to load?

So i've come to the conclusion that the sensor is not the CPU temp, mainly because when i first boot the board and the bios is showing me the temps, they are more in line with what sensor 2 is showing. I do think it is the northbridge, considering that on this model it is passivly cooled versus past models on which it was actively cooled.
