is this Athlon X2 really overheating?

Thanks in advance for any advice.

I'm building a rig for a friend out of some components we both have lying around and I'm having this strange overheating problem. These are the relevant components:

AMD Athlon 64 X2 5000+ Brisbane 2.6GHz 65W Dual-Core Black Edition CPU
ARCTIC COOLING Freezer 64 Pro 92mm CPU Cooler
GIGABYTE GA-MA78GM-S2H AM2+/AM2 780G MB
EVGA GeForce 8800GT 512MB 256-bit GDDR3 Video Card
ATX tower; case fans front and back, moving air in the same direction as the CPU cooler

The BIOS claims in the chip idles at 47C. In Windows, it idles in the low 40s. When we run any new-ish game (DragonAge is his test) or Prime95, it climbs steadily to the mid 90s. Turn off the game and it drops back into the 40s. (Same numbers from Everest, Speedfan, Coretemp, and the monitoring program that comes from Gigabyte.) But the system never crashes or shuts down. I've seen it at 104C...but the rig keeps running like everything is fine. Can it really be that hot?

I remember hearing somewhere that people had trouble with chips with these Brisbane cores reporting funny temps (back when they were new). If there is a thread on this somewhere here...many thanks for pointing me to it. (Searched but couldn't find one.)

Just FYI....everything is running at stock voltage and clock speed, the case is open, and I'm pretty confident in my thermal-paste/heatsink application, having done this numerous times before. In fact, that AC Freezer 64 has always worked like a charm, but we swapped it for the stock cooler and applied new paste (Arctic Silver 5) just in case -- same deal.

I'm close to the point where I just turn off the alarm and tell him to play his game and see what happens. Any ideas (that don't require buying tools or components) for figuring out whether the chip is really that hot?
 
Brisbanes usually have faulty temperature sensors. I should know, I've seen my 5200+ temps climb to 120C before stopping it.

Most of the time, the Brisbane temperature sensor is off by 10-20C. From your post, chances are that it's idling around 25C. I don't know what makes it to reach 100+C on stock cooler and stock speed, but eh.

You can even undervolt that brisbane to 1.275 or 1.2575 vcore and be fully stable (normal vcore is 1.35). I recommend you do this if you're not overclocking.
 
probably faulty....my old 5000+ BE idled at 20 somethin and that was on an ULTRA X-Wind cooler...

In which way? Reporting higher or lower than actuals?
 
Make sure you have the latest bios on your motherboard and re-apply some artic silver to the heatsink and see how that does. If it still shows high I'd say it's probably just a false reading and I'd just ignore it unless you have reason to believe it's really running that hot.
 
The core sensor on all of the Brisbane 5000+ Black Editions are indeed faulty. Use the socket temperature for a decent reading.

not true.....my 5000+ BE Brisbane has accurate readings(slightly off of socket, which is to be expected)
 
If all else fails...just feel the heatsink when it says its that hot. If it feels extraordinarily hot, then it probably is. If not, don't worry about it.
 
My 5000+ X2 Black Edition has funky temps too.

I just that as an excuse to upgrade to Athlon II X2 240 and sell the 5000+ X2 BE. Runs cooler, faster, and can actually overclock.
