I need some help guys I got my new RD600 from RMA

my idle cpu temp at same vcore of 1.52 is 40c(about 3-4 lower(ambients are couple of degrees cooler this am)
BUT my NB temp suck..at stock 1.3v..with a microcoo whisper XE it was 59C....
just could not seem to get good heat transfer(contact did not look really bad when I looked at TIM on the HS..

I switched back to stock HS and added a 50mm fan on top...idled at 55C at 1.3v
at 1.42v(that I needed befroe to run at 390 fsb) I idle at 59/60C...quick 3 min Prime blend and I hit 64C!!!!!!

I am going to go back and remove the 50mm and use a 120mm fan blowing on chipset....but that means I have to remove my new corasir memory cooler

what are the safe temps on this chipset

BTW my cpu did seem to load Prime 95 higher also on the new board(generally on old board I hit 56C max on coretemp....quick run and coretemp hit 53C...also it seems SG and coretemps seem a little closer off this board..generally at least 5C difference...but now 2-3C..load temps...idle temp all 3 are just about equal)

I have no idea if this board has a better temp reporting....or another other dead board???
