You say you never use water.  What do you use?  Water is a better conductor
of heat than antifreeze.  Straight antifreeze will freeze,(actually become
slush) and boil at lwer temps.  Water and antifreeze when mixed actually
chemically combine to produce mixture that freezes and boils at extended temp
ranges.  Concentration greater than 70/30 reduces protection factors.
