The vast majority of modern machines have working temperature sensors;
some just one or two (e.g. cpu and case temperature), others have a huge
range.
If you're unlucky and use an OS which doesn't provide access and
monitoring of these as part of the standard installation, third-party
software is usually available.
Non-CPU-bound servers can often benefit from enabling power-saving
features too (e.g. speedstep, powernow/cool'n'quiet). In some cases this
is very simple and offers significant reduction in power consumption and
heat generation.
