Surface area doesn’t tell the whole story!  The Cooler KX™ profile – meaning its fin height, fin count, and fin spacing – is optimized for performance in the absence of forced air cooling, where conventional wisdom dictates that there’s a point of diminishing returns, beyond which, adding more fins actually reduces performance because …

  1. Too narrow a fin spacing restricts convective air circulation.
  2. Most of the heat radiated by the fins gets reabsorbed (by adjacent fins).

Theoretical, at an ambient temperature of 24° C (75° F) assuming a uniform 60° C (140° F) baseplate temperature and that the only airflow is from convection.

Estimated (not accounting for smoothed/rounded edges and gullets).

The depth of the Plus model was increased in July 2014.  (Previously both depths were 1.5″.)
