How long have you had it? Did it seem to do this from the
very start (of use at higher load)?

If it's brand new still, I wouldn't hesitate to call them
any longer, if nothing else this is a documentation of the
problem on a new system should it come to the point of
having it replaced it is better that this was documented
right away, that it shipped with a *defect* per se rather
than the typical OEM presumption that it must've been a
customer/user change causing a problem (which we can't rule
out as of yet but you make no mention of anything you
changed that might cause this).

First, you can't just install Speedfan and assume correctly
reported temps, some boards use offsets or the sensor to
part correlation is mixed up. Double-check and compare with
what your bios reports in it's hardware/health monitor page
(presuming there is one).

I wouldn't call that shot through the roof, 13C change is
fairly minor, and typical... what you just described is
pretty common with any system and not a cause for concern in
and of itself... providing the temp report is accurate at
50C.

Check your bios for a CPU shutdown temp setting- it might be
set too low.

Open the case and point a desk fan at it, too see if this
reduces temps and if so, if the system still crashes. We
can't determine yet if it is temp related as 50C is nowhere
near hot enough to be a problem. Any system should still be
stable up around 65C, sometimes (often) even higher unless
it's overclocked.

Check that all fans are running and heatsink looks to be
installed correctly - unless there's some issue of voiding
warranty if you open it, I'm unfamiliar with their policies.
