Inaccurate temperature readings in MSI KT4AV Socket A (Socket 462)VIA KT400A motherboard?

Currently, my temperatures read in Linux with lm_sensors:

$ sensors -f
w83697hf-isa-0290
Adapter: ISA adapter
VCore: +1.65 V (min = +1.71 V, max = +1.89 V)
+3.3V: +3.28 V (min = +3.14 V, max = +3.47 V)
+5V: +5.08 V (min = +4.76 V, max = +5.24 V)
+12V: +11.61 V (min = +10.82 V, max = +13.19 V)
-12V: -11.78 V (min = -13.18 V, max = -10.80 V)
-5V: -5.05 V (min = -5.25 V, max = -4.75 V)
V5SB: +5.54 V (min = +4.76 V, max = +5.24 V)
VBat: +3.63 V (min = +2.40 V, max = +3.60 V)
fan1: 0 RPM (min = 10546 RPM, div = 2)
fan2: 0 RPM (min = 3426 RPM, div = 2)

temp1: +122°F (high = +39°F, hyst = -198°F) sensor =
thermistor
temp2: +144.5°F (high = +176°F, hyst = +167°F) sensor = thermistor
temp1: +50°C (high = +4°C, hyst = -128°C) sensor =
thermistor
temp2: +62.5°C (high = +80°C, hyst = +75°C) sensor = thermistor

I put both F and C temperatures FYI. temp2 should be CPU, and temp1
is motherboard. The numbers are identical in CMOS' readings. Aren't
these numbers a bit high? I don't have a lot of experiences with MSI
motherboards. My last ASUS A7V333 showed much lower readings in this
same PC case.

Full specifications: AMD Athlon XP 2200+ (Actual Clock Speed = 1800 Mhz)
CPU (Socket A; Thoroughbred-A) with a Thermaltake Volcano 9 (heatsink
and CPU fan), refurbished MSI KT4AV Socket A (Socket 462) VIA KT400A
motherboard, one Kingston DDR DRAM PC2100/DDR 266 (512 MB) + one
Kingston DDR DRAM PC2700/DDR CAS 2.5 (512 MB) = 1 GB of RAM, ATX
Mid-tower Tower Case; Enlight Power Supply (EN-8341934; Model:

NVIDIA GeForce4 Ti4200; 128 MB of RAM), onboard RealTek ALC650 6-channel
audio, Maxtor 53073U6 7200 RPM 30 GB ATA/EIDE, 6.4 GB Quantum Fireball
EIDE (6.4EX-A) HDD, Toshiba DVD-ROM Drive SD-M1912/TMAG 16X/48X, 3.5"
Teac disk drive, and an Intel InBusiness 10/100 (82559) NIC. Running
Debian OS (Kernel 2.6.11-K7).

Thank you in advance.

My MSI MS-7037 mainboard has the CPU sensor listed as a "Windbond 1
diode". The sensor is a Winbond W83627THF.

My mainboard has the same screwup - Everest reports it incorrectly.

My CPU idles along at 35C (95F). Under stress I have gotten it up to
around 45C (100F). I use CPU Stability Test by Jouni Vurio

Your temps appear far too high. If they are real, I would shut the
machine off before I fried something.

Does the BIOS report the same excessive temps? Set an alarm to find
out.

Put a electronic meat thermometer inside the case and see what the
case temp is. You can get one cheap ($20) at a BBQ store or
amazon.com. I have a Polder unit which is accurate enough. It has a
temp probe on the end of a wire which connects to the readout.

Look up the specifications for the ambient temperature of your CPU.
FWIW, Intel posts an ambient maximum of 38C. The assumption is that
you are using the approved Intel "retail box" heat sink/fan.

I think your CPU sensor should be a transistor (/etc/sensors.conf)

The temps can be given names of your choice via the above config file.
e.g.
label temp1 "M/B Temp"
label temp2 "CPU Temp"

The older version of lm_sensors gave incorrect readings compared with the
BIOS health screen, but the current version appears to be bang on (v2.9.1)

FWIW this KM4 + 2500XP gives the following temps via sensors:
M/B Temp: +20 C (high = +40 C, hyst = +39 C) sensor = thermistor
CPU Temp: +32.5 C (high = +56 C, hyst = +51 C) sensor = transistor (beep)
or
M/B Temp: +68 F (high = +104 F, hyst = +102 F) sensor = thermistor
CPU Temp: +90.5 F (high = +133 F, hyst = +124 F) sensor = transistor (beep)

Athcool is running. CPU 45C without it.

Forgot to add that this board uses the same sensor. w83697hf-isa-0290

 

OK, but why is CMOS/BIOS reporting the similiar values?
