Idle temp question, does this seem right?

Hey guys,

It's been a long time since I've done any overclocking, and I haven't done much reading on the newer chips (which I probably should have before posting.. i know...). I just picked up a 5000+ Black Edition, and I'm planning to do some overclocking on it soon.

When I slapped the new PC together, the board picked it up at 2.8Ghz, 200x14 even though it should be x13. That's not my question though.

I checked the chip out earlier today after letting it run 24 hours straight to give the AS5 some time to settle in and get cozzy. To my surprise, and delight, the chip seems to be running extremely cool compared to what I was expecting... I guess I'm wondering if this seems right, or if perhaps CoreTemp could be reporting wrong?

It seems to run idle around 5/14 for the two cores. The highest I've seen it so far was about 15/20 and that was while running iTunes, installing Photoshop CS3 and WoW in the background.
 
No way that can be right, those temps are barely above freezing. A bios upgrade on the motherboard may make the sensors display correctly.
 
You're not alone on the temperature thing. I am getting the same lower than ambient idle temps too with my 5000+ BE too. This was taken when I was at 3.0 but I am currently at 3.2.

I don't presume to be an expert on this, but from reading around, a lot of Brisbane's have an issue with reporting the temperature incorrectly. I guess it's not too much of an issue if you have adequate cooling and you are not pushing the vCore and clocks to the extreme, but I'd prefer to have an idea of what temperature I am getting under full load. Core Temp, SpeedFan, and Everest all give me the same incorrect temperature reading.

My board is the Foxconn C51XEM2AA with the latest BIOS if that matters. Also, while in the BIOS, the system monitor shows 32-37 degrees Celsius. Strange that I can't get decent temperature readings while in Windows.
 
I have a Brisbane proc on an Abit board, and the temps read wrong right after building it. It wasn't that big of a deal though because the case had a thermistor and LED readout that did show the correct temp. A few weeks later Abit released a BIOS upgrade that read the Brisbane temps properly in software.
 
Ok, well that makes a lot more sense. I was getting kind of worried as I've had this chip up to 3.4 and it was still reading under 25/35 under load.. it really made no sense at all.

I'm running an Asus M2N32-SLI. I'll check and see if there is a BIOS update that I can get for it to get these temps more acurate.
