Bad motherboard sensor

[Notquiteanewbie]

I have a bad thermal sensor.
More specifically on the CPU

CPU temp right now is 21c i'm using arctic ceramique
but still unlikely to be accurate

mobo temp is 29c pretty accurate

besides RMA'ing the board, what can i do,

is it worth buying those vantec nexus things or what

I have never truly trusted onboard sensors, they are either too low or too high...I have one now that starts off too low and then goes too high. I use a DigiDoc with two of the probes on the CPU on opposite sides of the slug and still get different temps, but al least they are close. The vantec looks like a good investment...somewhere between a DigiDoc and a CompuNurse setup. I really prefer a mechanical reading to keep my piece of mind

Unless your taking those readings from the BIOS, it is likely that the software that you are using to read the temps is not properly configured.

Well that is incorrect, all these programs get their information from the same source.

I did verify the validity of the data and it was consistent within 1-2c using motherboard monitor, bios, and asus probe.

Just wanting to know whether I should invest in the Nexus because I do plan on OC'ing

Ahhh, well...

I am glad to see that your DATA was verified in the BIOS.

You are however incorrect that all motherboards use the same "source" (as you call it) for the information. You see, my friend, each motherboard manufacturer has the choice to use one of several different monitoring chips. Myself, I have an Aopen AK77-8XN, it uses the Winbond W83697HF ISA chip. ASUS used to use their own proprietary one in the old days. If you are using Motherboard monitor, the later incarnations actually set up the proper sensors for you (you select your motherboard when setting the software up).

I would recommend that you do some research before declaring someone incorrect. I would suspect there is a lot you do not know about computers.

Just did some more research... there are a few different chips:

LM78-based (ISA or SMBus)
Asus AS99127F, Winbond W83783S, W83L784R (SMBus only)
Myson MTP006, MTP008
National Semiconductor LM78, LM78-J or LM79
Winbond W83781D, W83782D
Other SMBus hardware monitoring chips
Genesys Logic GL518SM, GL520SM, GL525SM
National Semiconductor LM80
Heceta 2-based (SMBus)
Analog Devices ADM9240
Dallas Semiconductor DS1780
National Semiconductor LM81
Heceta 3-based (SMBus)
Analog Devices ADM1024
National Semiconductor LM87
Heceta 4-based (SMBus)
Analog Devices ADM1025
Philips NE1619

Temperature monitors (SMBus)
Analog Devices ADM1022, ADM1028
Fairchild Semiconductor FMS2701
Texas Instruments THMC50

Super I/O with built-in hardware monitoring
ITE IT8712F
National Semiconductor PC87366
SiS950 (SiS540, 630, 633, 635, 730, 733, 735)
Winbond W83627HF, W83697HF

Super I/O with built-in fan monitoring
SMSC LPC47B27x (Intel OR840 motherboard)
SMSC LPC47M10x (Intel VC820, D815EEA motherboards)
SMSC LPC47M14x
SMSC LPC47B37x
SMSC LPC47S42x

Chipset with built-in hardware monitoring
SiS5595 (SiS5591, 530, 5600, 600, 620)
VIA VT82C686A/B (some Apollo MVP4, Pro, Pro133, PM133, PLE133, KX133, KT133, KM133, KL133)

...a program would have to be written to read the values of these chips. You cannot just use any program-- it must support the hardware chip. If you do, it is likely to give inaccurate readings (if anything at all).

I must be mistaken because I believe i didn't use the phrase "all motherboards" as you so eloquently put it.

phrase was "all these programs", generally speaking

More specifically, I was talking about my own setup and since I did install motherboard monitor I know for a fact that I choose the correct setting.

Its even more offensive to assume that I do not know a lot about computers when I was merely asking for recommendations.

I'm glad you were able to pull up all that useless information, and completely change the topic of the thread.

Unless my reading comprehension skills have diminished, this was the original question and the one that should be addressed. I really don't think a pissing contest is called for here and I strongly suggest that it cease.

Agreed, and withdrawn.

Apologies.
