Default Is this too much or am I wussing out?

I've been overclocking my E6400 with my new P35 Neo2-FR board but no matter how much I read about overclocking settings and results I can't seem to find a good answer to if I'm pushing things too far or if I'm just being a girly man.

A couple of notes:
For cooling I'm using a Cooler Master Hyper TX2 with AS5.
For temperature results I'm using the low and high from a successful OCCT graph with CoreTemp temps.

I can get a stable 3.00GHz overclock with:
FSB: 375MHz
CPU Voltage: 1.325V
VTT FSB Voltage: 1.250V
NB Voltage: 1.300V
Temp (Idle-Load): 39-56

Or a 2.67GHz OC with all default settings except:
FSB: 333MHz
Temp (Idle-Load): 35-50

My issues start to arrise when I push for 3.20GHz. I can get into Windows and basically taste stability at:
FSB: 400MHz
CPU Voltage: 1.400V
VTT FSB Voltage: 1.300V
NB Voltage: 1.350V
Temp (Idle-Load): 39-59

Here's what I'm wondering:
Some of the stuff I've read warns to never pass above 60 degrees, others 65, and some say you're good all the way to 80.
Do I need to be afraid of passing above 60 degrees?
Can I push the VTT and NB voltages a little higher without fear of damage? I seem to be able to raise them in lou of raising the CPU voltage but my motherboard marks higher values in red calling them "unsafe". Are they just covering their ass, or are mine high?

Thanks in advance for any advice. I'd really like to get 3.2Ghz, it felt faster, something the other OCing didn't do.

edit: forgot my temps @ 333

If it reaches 59*C in a stress test, then you would probably be fine going a little higher, maybe up to 65*C because you're temps will hardly ever reach that level during normal use. However, if it's reaching 59 just gaming or usual load activities, then going over 60 might not be the best idea. As far as the NB and VTT voltage, theres no harm in raising them slightly, unless the voltage limits on P35s are drastically different then the 680i, I'm running 1.39v on my NB and about 1.5 VTT.

Just a quick word; never raise your voltage unless you have to, especially your core voltage, you only raise it if you are trying to break a RAM limited clock. Try to max out your clock without raising your core voltage and then once you reach that wall, try to get around it by raising your core voltage.

I was trying to keep the core voltage low but I got to the point where I was detecting errors unless I upped the core voltage. Would I be better off increasing the NB/VTT voltages higher instead?

To me your NB voltage seems low but thats maybe what your board likes.
Id hunt around for people with similar setups and see what they do.

Thanks for the links. The last one said they needed 1.55V on the NB to get a e6300 overclocked good so I should be able to raise mine up higher than I had it.

I looked in my BIOS again and when they turn red it doesn't say it's "unsafe", just that it might cause instability.

can you take the cap off the NB sink and stick a fan on there?,
that might be a good idea

My mistake thats the SB ,

Put a fan on the NB

I'm getting a fan to do this but I'm not sure which way I want to blow the air. Should I blast air straight at the motherboard, or up from the bottom towards the CPU?
My 8800GT is creating a giant wall that blocks a lot of airflow in my case. Combined with my new fan not blowing air down it makes my NB kinda warm.

you seem to be describing putting a fan inside the case somewhere pointing in whetever direction, That sounds bad like it would cause bad flow (man).

Can you put a 40/60mm fan on the NB sink (blowing downwards towards the chip),loop it round the heatpipes with thin zip-tie or wire of some kind.

You might have been thinking about wedging a fan in the middle of the U shaped NB sink but the pipe in the middle (the hottest one) wouldn't get any benefit from that
