cud be m/b problem, i had problem in Intel DG965WH & P4 3.06 procy.
the CPU Heat sink randomly got really hot, otherwise i can directly touch the CPU heat sink & the tem was very low (heat sink wud remain warm but not hot).
the chipset heat sink was always REALLY HOT.
RAM stayed warm all time.
i faced this HOT problem

only in this new dg965wh m/b.
in my present ASUS 915g m/b, every thing is warm (not hot), after some gaming sumtimes i touch the cpu (same procy) & chipset heat sink (did this to make sure cpu was fine), they remain warm, especially the procy.
(i cudnt use a s/f for random temp. logging as i cudnt find one supporting XP Pro (non sp2).
