Where are the LM99 chip temp sensors on speedfan monitoring?

I have the Abit AN8 Sli, and speedfan show 6 temp sensors

1. cpu
2. pwm
3. HD
4. sys
5. LM99
6. LM99

what are these LM99 sensors monitoring???? the "BUS" info is "12CNVidia SMBus"

A guess: graphics card.

seems like a good guess as one LM99 can measure a diode junction from another device as well as it's own temp. So, probably measuring the GPU board temp and the GPU core temp.

well..i thogut graphics card as well...HOWEVER, its a 6600GT and the sensor in advanced settings, and NVtemp logger, shows a temp that is ALWAYS different.........

so that brings it a total of 6 sensors by speedfan, and the one on the graphics card that the display settings show

sorry for a bump, figured second page didn't get much visits.... anyone??

I also have 6 temps, and I know that there's no GPU temps in my SpeedFan with my graphics card, I used a PCI graphics card to test. Do the same if you have one.

1 - CPU or PWM, still don't know,ISA
2 - ITE8712 chip, you can call it case temp,ISA
3 - nF3 temp,ISA
4 - useless temp,ISA
5 - useless temp,SMBus
6 - CPU temp,SMBus

It's easier to help you if you tell us the chip and bus for each temp.

Perhaps it is your video card, and you just need to adjust Speefan's value to nVidia's. That's what I had to do for my 6800.

Yup, after checking, LM99 is my 6800. My LM99 Temperature 1 offset is 0 and Temperature 2 is 9 (under "advanced" then select the chip). You might have to offset yours to a different difference. BTW, for me at least, Temperature 1 is the card's ambient while Temperature 2 is the core.

humm.....ok, i will look into this further Badger....i will offset if the temps change identically. thanks

I've noticed that they change slower in Speedfan than in the nVidia view. Just takes a little experimenting to find a good value.
