I'm checking the operating temperatures of th components of my PC prior to getting the caselid back on (i had to repair a NB fan failure and heatsink mounting HW fail which left me having to operate th pc with the case open, ahem cough for a few years )
All seems fine on infra red thermometer and thermocouple. though I could have actually had my CPU fan operating slower ... and quieter.
I installed Speed Fan - so I canmonitor the temps over a period when I shut the case again - and reading the temperatures from the various OEM sensors. There are 5 different temperatures displayed.
I have pinned down which ones are the HDD (that one was obvious), CPU and Northbridge (I think).
HDO on AdvSmart bus $0 HD0
CPU on ISA bus $290 chip = Winbond
Chipset on ISA Bus $290 chip = Winbond
Though I'd take all readings with a pinch of salt these correlate with thermocouple and infra red measurements. i took into accoun the loading effect of the CPU fan on the now passivley cooled NB.
There are however two more temperatures and I'm not sure the location of the sensors
Temp 1 ACPI on ISA bus $0 (currently 64 deg C doesn't modulate)
Temp 1 Winbond on ISA bus $290 (Currently 30 deg C, modulates 27 to 31)
On the Speed Fan winbond config:
sensor diode 1 - thermistor
sensor diode2= PII [sic] diode
sensor diode3 = Thermistor 2N3904, (2N3904 a thermistor? orly?)
I think I can put down the ACPI reading of 64 as spurious, it doesn't correlate with thermocouple or infra red.
Anyone know where these are?
