From the official excerpt at www.dndinsider.com
"A minion is destroyed when it takes any amount of damage. Damage from an attack or from a source that doesn’t require an attack roll (such as the paladin’s divine challenge or the fighter’s cleave) also destroys a minion. However, if a minion is missed by an attack that normally deals damage on a miss, it takes no damage."
Regardless of how many hitpoints or temporary hitpoints or any other kind of hitpoints, Damage from an attack or from a srouce that doesn't require an attack roll destroys the minion. THey could have 100 hitpoints and they still get destroyed since the rule never states anything about hit points at all, only that they are destroyed.
