The fact that it ran for 3+ hours is good.
Your PC is stable and the CPU voltage and
memory setting are in the safe range.
What I don't like is the 55 to 58 degree temperatures,
the variation is OK, but even 55 degrees seems too high.
I need to do some research to see if this is normal for your
CPU and the Heatsink/fan that you had installed.
One thing you can do if you haven't done so already is to
open the case cover and check for dust buildup in the fins
the are part of the CPU Heatsink.
And also the openings in the case need to be free of dust & dirt, too.
Depending on the mfr, it's not that unusual to see 55° or so on the cpu.
Walmart specials always seem to run hot - those are cheapest-bids
without much concern for anything but meeting specs, regardless of how
barely they meet them. I've been told that some companies sort ouf
their "junkers" to fill their orders to the big box stores rather than
put it into the repair lines; I think I believe it. I've even seen two
machines, both Walmart specials, where the cpu's were under-clocked,
apparently to meet the heat specs because the cpu in both was running
real hot. At first I thought it was a clock-down ckt based on temps,
but then I discovered the speed jumper. I replaced the cooling towers,
used the right amount of thermal compound, got a better fan and in both
cases clients were ecstatic over how much better they worked. Oh yeah,
and one sink had a bad clamp; hardly held the sink in place on one side;
I could slide a piece of paper under one side of it.
Cables can mess things up too, especially the wide IDE cables. There
should be a clear path to the vent where the air is intended to exit the
case. In a good machine they're tied so they almost have to be in the
right positions. Nowadays anyway. It didn't use to matter, but ... it
does at the speeds they're running now.
There are two variables to check there, too: The location of the
sensor (internal to the components or actual separate sensors glued to
something) is important and can make the readings questionable too.
I've always thought it was "cute" how you can always get a temp reading
on a hard drive but not the cpu. There have to be reasons for that
beyond the obvious.
