You are using an APU (basically a CPU/GPU combined).
If you are using a separate discreet GPU, the APU may still be drawing power to support both the CPU and GPU portions. As you are not using the onboard GPU side of things, the APU can get by with drawing less power than usual (might be a little vague, but I think stock it runs around 1.45v, a standard AMD CPU usually uses 1.275v).
You can set these things in the BIOS, just drop your Voltage down one segment at a time, run some stability tests, then repeat until you fail. Then notch it back up one.
Of course, all this is pointless if you're not using a discreet GPU. :)
Not being an APU user myself, so bit lacking in the info and just pulling stuff I find off Google.
Going to get 2-3c lower in those situations, which if correct means he'll only be maxing out around 80c...still something distinctly wrong.
The max safe operating temp for his model is 74c.
One this I would say is that if you're using a discrete graphics card rather than the built in, the CPU could be getting overvolted (from the extra the GPU side would be using). So you can try dropping it down to reduce temps as a stopgap with potentially no negatives.
Probably may want to re-gunk/seat your cooler too (with paste, less is more, you want as much direct contact as possible with the paste just filling in the gaps), and check your case airflow...got to shift the heat out of the case, or it builds up quickly.

Just got back from my first tour of the eastern front. Have to say the game has a lot of potential but...it's horrendously optimized with more bugs than an ant's nest.
If anyone is thinking about buying it, i'd advise waiting a month or two for Tripwire to fix things up, might even get a price reduction by then to boot. :)
You should be able to scrape together a Bf3 capable PC for around the £250-300 mark (assuming you have a few spare parts like monitor/dvd drive etc), not going to run it on super settings but it will do. All these damn eejots talking about how you'll need a 580 are talking out their arses.
Apparently the rig they used to showcase it at GDC was running a single 580gtx. Considering it was likely running with everything on max at 2500 res. I doubt it will be too hard on the PC if you drop some of the settings down.
