I'm running my northbridge @ 1.5v and my vtt @1.4. I've seen many northbridges on here as high as 1.575v How high can I go with my northbridge? I have MSI heatpipes on my P35 so the cooling is very good.

I've also added two Thermaltake Thunderblade 120mm fans to my Thermaltake Soprano case which has reduced my 8800gt idle and load times by 4C and reduced my load on my CPU by 4C as well. These fans are pushing 78 CFM and producing 21db.

If I crank up my northbridge more than 1.5v I can get more than 3.6Ghz
My Q6600 idles at 39c/37c/35c/40c and the highest temps recorded under hours of gaming load 67c/63c/59c/62c
