I don't know what made you think it's wrong, it might well be the reason.
If the power supply is hot it might switch off. Not by a sensor giving a
signal to CPU and CPU shutting everything down, but by a simple temperature
protection inside the power supply cutting the power as for emergency.

I am absolutely sure you should be able to set the threshold for max
CPU temperature in BIOS. It would be somewhere in the 'health status'
menu where you also see the fan speeds and power levels.

The temperature coming from /dev/sda is your hard drive's temperature.
It's a part of SMART information and you could also read it using
smartctl from the smartmontools package. You should be able to see two
more temperatures - the CPU temperature and the Motherboard temperature.
Check the lm-sensors package, it should give you this ability.
