Hitting 4GHz

I have a 2.8E right now, but aiming for 4Ghz as I hear thats the sweet spot for Prescott's. Realistically, how can I achieve this, hopefully on air?

I'm thinking on getting a 3.4E and then clocking that, but I have been able to get my 2.8E to POST at 3.8, though its running at 1.52v and i'm probably not going to puch it much farther than that.

Right now i'm oc'ed to 3.4 on stock voltages, idle temp at 48C load temp at 60C with a zalman CNPS 9500.

I don't care too much if I shorten its lifespan to a year or two, by then i'll probably be switching to M2 and PCI Express.

Motherboard is a IC7-MAX3, and i've noticed that what I set in the BIOS for CPU voltage is slighty higher than what I see in CPUZ, and in CPUZ the voltage will fluctuate as i'm sitting here watching it. I know i'm 100% stable at 3.4 because i ran two instances of Prime95 for 2 days straight with no errors, though anything higher than 3.5 will boot into desktop but produce Prime95 errors.

So, you think to get it higher, I should pump more juce than the default 1.38v going to the CPU?

Opinions please!

EDIT:
Thinking of removing the IHS on my P4. Opinions on this?

OMG THATS BURNING UP!!! JK

Im so used to my AMD dual core system idling at 30C and load 38C while overclocked 700mhz that those temps seem high but yet again thats INTEL, which I know nothing about. My old AMD XP 3000+ idled at like 45 with load at 55. My system now makes me feel happy. :p
 
I'd reseat the HSF, or purchase something like a TT Big Typhoon or Scythe Ninja. You need some lower temps before you consider pushing it higher.
 
its a pentium 4, not an amd...so he can possibly hit 4.0ghz on air with adequete cooling, aslong as nothing else holds him back [ram, mobo, throttleing etc]

i recently saked opinions on removing the ihs on my p4 prescott and they told me its soldiered on and next to impossible to get it off, however 70-75 at load for the prescott is an acceptable temp (acceptable as in it will run fine at that temp) so push it as far as you can until it starts to be unstable, if you hit 4ghz congrats.
 
Don't forget he is still using a S478 Prescott.. Those are the hottest modern CPUs
