New home built, CPU software says high CPU temp....

[wscreate]

Hi all.

My home build system was built around a donated AMD Sempron processor. Everything else is new. I downloaded software to help me monitor temps from motherboard sensors, and it is giving me high readings for the CPU while the BIOs temp sensor for the CPU does not give a high reading. The software is called Hardware Sensor Monitor and is at http://www.hmonitor.net/

** With Windows XP Loaded, at rest.
Case Temp
30-32 C consistently
CPU Temp
Software: CPU1: 102 Celcius
BIOS: CPU 44 Celcius

I have tried a second software program and it also gives me a similar reading where the BIOS continues to give me a 40 C range reading. Is this number accurate, or is the motherboard somehow misconfigured for the sensor for the CPU? (See my hardware list below). I don't do any gaming on this pc, it used mostly to surf the web and I use a program called HomeSite by Allaire to program code.

CPU
Socket 754, AMD Sempron(tm) Processor 3000+ (Donated to me by a friend)
ThermalTake Venus7, CPU HeatSink/Fan, 22-37CFM, 25-42 dBa
Heatsink installed with Arctic Silver thermal paste between HS and CPU
Heatsink is installed properly and in place.

MotherBoard
EliteGroup (ECS), Socket 754, K8M800-M2
VIA VT8237 Chipset
MicroATX form factor

Memory
DDR400,
1 X 512mb
1 X 256mb

Case Fans
120 mm exhaust fan, rear

Peripherals
DVD/CD Rom Drive
LinkSys PCI Wireless Card

Motherboard has onboard video and sound.

I am new to PC building, so I can't figure this out, but maybe the following illustration from the temp monitoring software can give someone a clue.

CPU1 doesn't exsist on your system, disregard it.

Your CPU0 should show the actual CPU thermal.

Also, looking at your second screenshot, it lists 'Temp3' as -86 celcius, if that was true, something in your case would be much colder then water ice.

Natural conclusion, the readins are inaccurate.

EDIT:
If you REALLY care about the thermals on a non-gaming, non-overclocked system, try this one.
