Subject: Why do they call it a \'heat sink\'

I thought it was \"heat sync\" at first, but saw that it is now \'sink\' -- what the heck does that even mean?

The word sink has always been used (AFAIK). It\'s alludes to the fact that heat is _drained_ from the source. In non-PC parlance, a sink is the method used to _drain_ e.g., water etc.
_sync_ is an abbreviation of the word syncronisation (to equalise etc). No way would you want to synchronise the CPU environment (chip / Integrated Heat Spreader or IHS) with the cooler ... that would simply mean equalisation of temperatures and very little cooling would occur, followed very soon by the expiration of the CPU.

It relates to the 2nd law of thermodynamics. In a thermodynamic cycle energy is absorbed at the high temperature Resovoir and heat is rejected at the low temperature sink.

So basically when applying this to our system of a CPU and heatsink. The cpu is the high temperature source(resovoir) supplying energy to the system in the form of heat , and the heatsink is rejecting the the heat from the system to the ambient air , hence \"sink\".
