E8400: 57c for load temperature?

I'm using an Intel E8400 on a P5B Deluxe motherboard and I'm getting around 57c for a load temperature in RealTemp (TJ Max = 100). Is this normal for stock cooling?

Here's what I've noticed:

IDLE:
Vcc = 1.104v - 1.232v (changes)
Frequency = 2000 MHz (6.0 * 333 MHz)
Temperature = 38 / 36c (core1 / core2)
Distance to TJ Max = 62 / 64 (core1 / core2)

LOAD: (orthos)
Vcc = 1.224v
Frequency = 3000 MHz (9.0 * 333 MHz)
Temperature = 57 / 57c (core1 / core2)
Distance to TJ Max = 43 / 43 (core1 / core2)

I'm using stock Intel cooling but I'm hoping to achieve a mild overclock of around 3.2 GHz. Of course 3.3 or 3.4 GHz would be even better but I'm not sure that's possible.

If I leave my Vcc on AUTO than my load temperature at 3.2 GHz gets up to 65c+ which kinda scares me but I THINK it's because the Vcc gets cranked to around 1.3v.

for stock cooling on a load 8400 i think thats pretty good, its under 60 so thats good.

That is a fine temp. When OC'ing make sure it doesn't get above 70c. Either it'll fry the chip or mobo or, if your lucky, your computer will shut down to save itself.

Is it an E0 or C0 E8400? If it's an E0 it can do 3.6Ghz on stock voltage (1.225v). With the vcore setting at "auto" it will give way too much voltage, hence the high temperatures.

Thanks for the replies everybody.

CPU-Z is reporting "Revision E0" for my processor. If I can get 3.6 GHz on stock voltage (with stock cooling?) I would be THRILLED!

Should I change my Vcc in the BIOS from auto to 1.225v?

If I get around 67c under load (orthos) would you still consider that "safe" or too hot?

Yeah first try setting your vcore manually at stock speed, and see where the temps will get at. Then increase the FSB and test again.

If you want to do a serious overclock you'd be better off buying a decent cooler though. The stock cooler is pretty bad.

I think that the Vcc is automatically being set to "stock voltage" (1.224v) because that is what CPU-Z is reporting when my system is under full load (orthos). So it seems like 57c is what I get at that voltage.

However, if I increase the FSB to 378 (3.4 GHz), I'm guessing that I'm going to get around 60 - 65c or maybe even more.
