Problems with 3200+ venice stock HSF

I'm having problems with temperatures on my new 3200+. Without overclocking teh temp is reaching 55-56c running prime 95. I've tried reinstalling teh hsf with arctic silver (removing previous compound of course). I've tried running with the system open and an overhead fan blowing on it, but no help. I've tried every imaginable configuration of my 3 8mm case fans and 1 36cfm slot fan. I don't understand why it's running so hot. I've talked to many others and thier temps are in teh mid 30's to low 40's at full load overclocked with teh stock cooler. Is it possible my system is just reading the temp wrong? I know this is dangerous, but i OC'ed it to 2.5hz just to see and it ran stably for 6hrs on prime95 at "63c", would this be possible if the temp was correct?

I think i've figured out the problem. I read somewhere that the bios originally installed in my motherboard does not recognize the 90mm vs the 130mm Athlon processors so the default voltage is set to 1.5V. I'll try flashing the bios and checking voltage and if that still doesn't work i'll try manually undervolting the processor.

I have an MSI K8N Neo 2 Plat. that did the same thing. Under full load the stock HSF sounded like a plane.

I upgraded to an XP-90 with a quieter fan and it was still sitting around 45-50c, down from 60c.

Eventually I learned that the MB set the default CPU voltage at 1.5 When I lowered the voltage the temps dropped about 20c and the world was a better place.
