Lapping...worth it?

Hey All

I am thinking of lapping my Q6600 and Megahalems. Right now I can get 3.4Ghz stable and I think I can get 3.5Ghz stable too but the temps are too much for my liking really. My aim is 3.6Ghz so my RAM runs 1:1 rather then over/underclocking it.

I have read that lapping can take up to 10'c off if done right, but how correct is this? It seems like a mixed subject really as some agree and do it and others that have also done it say it had no effect. Opinions?

What are the risks involved too? I mean, how much chance is there that I might go wrong or lap too much etc?

I am not looking for a miracle from this lapping but if there is a chance to drop a good few degrees then I will probably do it.

Thanks

hmmm how high ARE your temps or do you just 'not like' them because they gotta be really high to actually limit your overclocking

Basically at 3.4Ghz on ITB I am about 82'c on my cores, 3.5Ghz goes over 85'c so I think its too hot. I have my CPU to auto shutdown when the CPU temp is over 75'c and it shuts down when testing. 3.4Ghz is under 70'c, 3.5Ghz is hitting 75'c. Annoyingly due to always having a hot university room my ambient temps are very very high, for example on a normal morning I am around 24-27'c in my room and mid days I am sometimes 30'c. Its extrememly annoying!
 
82'c is toasty for cores but thats under IBT, Prime95 doesnt go over 75'c.

For 3.4Ghz I am using +0.150V which I think is 1.375V...my BIOS doesnt display the ACTUAL voltage. CPU-Z shows it hanging around 1.375 under full load.

My case has a 140mm at the front pulling in, and 2 fans exhuasting, 1 top and 1 back, both 120mm. I use a Megahalems with an Apache Black on my CPU also. There is not a single cable that goes over my motherboard at all. The only cable that "intrudes" is the 2x6pins for the GFX, but they go round the back and out through the motherboard tray.

I think thats all the questions answered.
 
My Q6600 can do it though, its just heat being the issue. I really think that I can get 3.6ghz, but again, damn heat!
 
Doubt there is a guide for the Coolit system, its more of "get the theory and apply it to your needs" type thing.

With the technique, correct me if I am wrong but its basically using grade 400 > 1600-2000ish, on a flat surface (glass is best), slight water added to the paper, do this until you basically get a shiny chip?
