I wouldn't worry too much re nortrhbridge, at least on this motherboard. You can
Add a fan, THat's a 60mm fan with double sided tape , but at the moment I'd not worry too much
regarding
cpu coolers I'f look at the
Xigmmatek coolers we've just reviewed. They are a match for most top end coolers, but with a modest £.
yes it does sound like prime failed due to memory failure. Is this your
ram ?
4GB G.Skill DDR3 PC3-10600 (1333MHz) CL8-8-8-21
If so you need to increase your
vdimm to 1.65V whicj is the rated voltage. Auto will use the jdec value of 1.50v
so in
bios select :-
DDR3 OverVoltage Control...(1.50v)..: +0.15v (note 1.65-1.50)
It may also help to increase (G)
MCH OverVoltage Control from normal + 1 or 2 notches.
Try rerunning prime & see how it goes.
