I picked up a Intel E5200 for $40 on black friday. Not much of an upgrade from my E2160, more or less just an overclocking toy.
I almost freaked out, my BIOS cpu temps posted 90c at boot, and would shortly shut down. Had to disable the CPU overheat auto shutdown, once booted into windows Core Temp posted 31c.
Also for some reason the multiplier is stuck on 12x, should be 12.5x but I cant change the multiplier now like I could with my old E2160. I'm using the same BIOS rev. No problem though since I'm overclocking, just strange.
Another annoying this is that since my motherboard thinks my CPU is at >90c, the fan runs wide open now. Having to use SpeedFan to slow it down to 55%, but the program always defaults back to 100% when I reboot. Any ideas, or maybe another program. I plan on getting a quiet hs/fan but I can't right now.
One last thing, why is 1 core always 5-6c hotter then the other while under load? My old cpu was always within 1c.

Big whopping 42 point difference. This benchmark is bust.

specific save point with lowerst fps I could find using Fraps
old E2160 - 63
new E5200 - 78
My fallout fps increased 25%, not bad for a $40 upgrade. I'm totally happy with my purchase plus I have a use for my old CPU.
