I'm new here, but have been lurking a long time. I recently installed an FX8350 processor and immediately noticed quite the jump in temps. The processor went on the board, not long after I installed a new GPU. The previous processor was an Athlon II x645 Propus. Previous GPU was an HD6870. My rig is primarily used for gaming (LOTRO and SWTOR), but I am looking into making it into a developer platform as well (MySQL, SQL Server, Visual Studio).
I had no issue playing LOTRO, other than the temps. CoreTemp was reporting spikes as high as 71C. Not only that, I could feel the difference around the box. Ambient temps were somewhere around 68-72 F. Well, after logging search legs all around the Google-verse I finally came upon the topic of Core Performance Boost. I disabled it in BIOS, then tweaked the multiplier until I got my temperatures down to a satisfactory range. Ended up at 20.5x and this has been stable. I tried 21 but although no black or blue screens of death, I did get a system freeze. So I went back to 20.5x with CPB disabled. No other mods or tweaks in the BIOS.
Highest spike temperature I have seen since the BIOS update was a spike to 51C, averages between 44-48C. This was during game play. CoreTemp has reported a low of 14 and high of 31 during non game activity. This makes me happy. This makes my fans happy. This makes my MoBo, memory and processor happy
Presently running at 4.1 GHz with none of the heat issues I was experiencing prior to the BIOS change. I am not an OC'er. No interest in going there, although you OC'ers are a wealth of very helpful information. My rigs have to survive for some time.

eta for what it is worth, I disabled Core Parking via the registry. As an aside, and just for informational purposes only, my Windows Experience prior to the hardware upgrade was 7.3, 7.3, 7.9, 7.9, 7.9. After the upgrade and reassessment: 7.8, 7.8, 7.9, 7.9, 7.9. After the BIOS mods: 7.8, 7.9, 7.9, 7.9, 7.9.
