I have a Toshiba Satellite P755-S5215 laptop, from 2012. It's got a 2.2 GHz Intel Mobile i7-2670QM CPU, with a stock board and integrated graphics.
It's a good workhorse, but sometimes it undergoes an emergency poweroff because CPU temperatures exceed what my laptop's physical thermometer considers a critical
level of 100° C
. This is usually when I'm playing a resource-intensive game and haven't throttled CPU throughput, or when systemd wants to be annoying.
On the other hand, if I'm playing a resource-intensive game and I remembered to throttle the CPU's governors, the temperature sits around 87° C
, which is a degree above what the thermometer considers high
. The computer can run like this, but I wonder what the board and parts are actually capable of.
Most of the snippets of data I've been able to find say 100° C
is typical, but my guess is that's just a ballpark for manufacturers and OEMs to cover their hindsides against a lawsuit.
Could maintaining a CPU temperature tolerably below the critical
level (but still hot enough to, for example, give any human severe burns) have permanent, destructive effects on my computer's components?
I use lm_sensors
to read CPU temps.
