I remember a big debate "back in the day" about the effects of shutting down your PC at night and the effect on the health of the CPU. The theory at the time was that by shutting down your PC every night, the temperature fluctuations would put more stress on the CPU, shorting its life span. However, the other side said that leaving on your PC all day and night would spend more time running and reduce its life span, so only having it running when you needed it was better. I think a website did a test and found it makes no difference, but I remember it being a big topic around the 2000's (it might have been related to AMD chips at the time running extremely hot)
AMD's first Athlon chips did not run particularily hot. They needed a fan, just like Williamette chips, but actually used less power than the competition. The difference was they had no internal, on-chip diode. If the heatsink and fan fell off, then the chip could cook itself. The boards had a thermal sensor to initiate shutdown if the fan stopped working. But it's debateable if it would detect it quickly enough if the entire cooler fell off.
In that scenario, shutting it off seems better. But it might roast itself on start up anyway.
In my recollection, the tale was not temperature changes on startup, but the various electrical issues of getting things moving from standstill.
Either way, I just always used sleep-mode.
