I stand to be corrected by someone more current.
Common Halon simply starves the fire of O2- little damage- BUT does little to cool hot objects which can reignite. Water cools and is used fo major computer installations on the ground- really with little damage to commercial grade electronics. Damage to avionics fires in an airplane is far down on list of priority issues.
