1.8A and Abit SD7 - CPU Reads 90C?!

[stefanb]

I just got my Northwood 1.8a and Abit SD7-533 board in friday and man it is fast. (got it up to 145FSB with no problem, 2.61)

One problem though, the Bios shows the System temp to be 66C, and about 2/3 of the time the CPU reads 28-32C, 1/3 it reads 90C+!

MBM and Sandra both report 90C+ on the CPU

What is up with this? The heatsink is seated, I removed it, cleaned and lapped off the thermal pad and used AS3 and it didn't make a difference. Box fan on it with no sides and it didn't make a difference. The machine is very stable, but something is wrong with the readings for sure. It's a WinBond W83697HF on with the SiS645 Chipset.

If anyone has ANY ideas on why I would get these readings, please let me know. I will give the Abit tech support a firm talking to in the morning!

are you kidding? youre lucky to get a reading at all!

dont worry about it - eventually new software will work.

nice OC
what voltage and memory multiplier are ya runnin?

90 degrees? That's nonsense.

First of all, if it were that high, the Clock-throttling self-protection mechanism would kick in. Secondly, I'd rather trust an Intel mobo on the temperature readings.

SiSoft Sandra can't really be trusted - I doubt it's able to get the temp-readings off the CPU directly. And WinBond Doctor ... well, I don't have a high oppinion of it. The CPU does have an on-die thermal sensor, so you should be able to get "normal" readons (say) on an Intel board or somesuch.

90 degrees is definately nonsense. I'd not take this too seriously, as long as you have a good Fan & Heatsink (example: those that come with the boxed CPU) .

Hope this helps a bit .

Edit:
BTW - you *SURE* this is degrees C and not Fahrenheit?
