Recently my system has been suffering from what appear to be numerous hardware defects. Most critically, my system has apparently been overheating (under medium load) and summarily shutting down. One factor which I have already discovered is that the back fan is not spinning. It appears to just be broken because voltage readings (with a volt meter, not sensors) on its pins show 12V. I suspect, though, that the fan isn't my only problem.
How can I determine the extent of my hardware damage using acpi, sensors or other tools? I am getting numerous bad readings and I'm not sure whether they correspond to hardware failures, nonexistent sensors or just misconfigured measurement software.

Using the KDE plasma widget I can see that
temp1 fluctuates between 89-92 while
temp2 reads a constant 33 (ie, it's broken). I never really paid much attention to this until my computer starting getting unnaturally slow under medium loads and summarily dying. Then I saw that
dmesg was littered with
[ 1561.568839] CPU1: Core temperature above threshold, cpu clock throttled (total events = 1) [ 1561.568857] CPU0: Core temperature above threshold, cpu clock throttled (total events = 1) [ 1800.040047] Machine check events logged
I don't have much experience with deciphering temperature readings or generally sniffing out bad hardware--could this whole phenomenon really be explained by a dead back fan? I've taken off one of the box panels (which would seem to offer about as much extra ventilation as the little 4" fan) and the CPU, PSU and front-of-the-box fans are all running on full duty cycle but it doesn't seem to make any difference. I'm still getting very high temp readings and frequent shutdowns. What can I do?
