Temp question with Shuttle AK32VN motherboard

[Salvador]

Hello.

I just bought a cpu/mobo package with a Shuttle AK32VN Via chipset KT266a motherboard. I tried running SiSoft Sandra 2004 on it and by the second run, the board temps spike to 60 degrees Celsius and Sandra's default temp protection kicks in and shuts off the burn in. This happens even when I select normal and not high stress. Now.. I can run a ECS K7S5A (SiS chipset of course) Pro all day long like this in high stress and the temps stay steady at about 37 degrees Celsius. Both boards are passively cooled and are in the same kind of case with one case fan.

Also.. The Shuttle board is running an Athlon XP1800+ and the ECS K7S5A Pro is running an Athlon XP2400+ and it runs hotter with the same heatsink (as it should).

Why does the board temp spike on the Shuttle board? Is this normal for this kind of board? Could it be defective if the temps spike like this? I have about 5 days left to exchange it. I don't want to bother exchanging this if it's normal, but I don't want to be stuck with a bad board either.

TIA,

Sal

Do you think it's a flaw in the motherboard that I have or do you think it's a design problem? I need to know whether I should exchange it or not.

hiya Sal what hsf you running and does it have thermal pad or paste for the TIM ..?

Heya Scrappy! I'm using a wonderful GC68 (stock fan) with AS Ceramique (trying to use it up because I have AS5 now). The cpu temps are fine and stay steady. It's the motherboard temps that spike after the second run in Sandra. They are normal and then they just spike right through the roof and Sandra shuts it down. I don't know if you've used SiSoft Sandra 2004 yet, but the burn in wizard has a nice graph to show the temps.

Someone else asked about the core temps? Why would that make any difference with the board temps?

BTW.. I've been running my K7S5A Pro all day long now on high stress and the temps are ruler flat for the cpu, mobo and auxilary (whatever that is).

Thanks again.

I know that nobody has answered, but I have an update. I set Sandra's burn in temp protection to 70 degrees Celsius and then ran the burn in again. I was able to run the burn in 40 consequetive times. The funny thing is that the graph that shows the temps in Sandra 2004 looks like a stock market graph. The min. temps were 14 degrees Celsius and the max was 69 degrees Celsius. It would fluctuate 30 degrees from run to run. This can't be right, can it? I think the sensor is off. I put my hand on the board and it's barely warm to touch. Certainly not 69 degree Celsius.

Because the mobo temp sensor seems to be off, would you bother RMA'ing the board or just keep it?

Also... What is the aux temp listed? Where is that reading coming from?

Thanks again.

was a long day for me but anyway..

yep..sounds like its a bad temp diode(or whatever is being used to get the reading)

if its just the temps reading out wrong and nothing else is wrong..be easier to just keep it(BIOS flash might be helpful but I dunno)..aux temp..same..I dunno..sorry not much help on it.

I have 2 brand new ECS K7VTA3 rev. 8 c mobos.
Sandra, AIDA332 and SpeedFan all have troubke reading the temps and voltage also.
All my power supplys will read 8. volts or even 6 volts volts on the 12.0 + line.
CPU voltage reads ok.
I think maybe some boards are not supported completely in the software.

Hi Scrappy!

Thanks guys! I appreciate the advice. After I set the maximum temps up a bit, I was able to run Sandra for more than one run and realized that there is no way that the temps could be accurate. How could it jump from 69 degree's Celsius to 14 degrees Celsius on the next run? I think it would be impossible that the board would ever read 14 degrees Celsius unless it was off. Also, when the temps read the highest, I felt the chipset heatsink and it wasn't even warm to the touch. I can definitely live with the temp sensor being incorrect. What scared me was when Sandra was shutting it down, it has spiked to over 60 degrees and I had no way of knowing if the temps were correct or not.

I'm keeping the board.

Thanks again!
