I've realized that the output of sensors says
but the manufacturer's spec for my CPU (Intel Core i3-2100 CPU) states that the max case temperature is 69° C http://ark.intel.com/products/53422/ .
Adapter: ISA adapter
Physical id 0: +35.0°C (high = +82.0°C, crit = +102.0°C)
Core 0: +34.0°C (high = +82.0°C, crit = +102.0°C)
Core 1: +27.0°C (high = +82.0°C, crit = +102.0°C)
So,where do those numbers come from? Is that some random value,or are they read from a different sensor location?
I've never actually pushed my CPU beyond 55-ish,but what will happen if eventually some application will push it further?
Does the system still know when to throttle it down,regardless of the accuracy of those max values in sensors?
On a related matter,my motherboard Asus P8H61-M LE has three different performance profiles and different fan profiles as well,I've never checked if they make actually a difference,but -come to that- does Ubuntu override those BIOS settings or respect them?
