The buildings fell in under 10 seconds. A fire cant make a steel building fall in ten seconds.
Jet A-1 (the most likely specification of the fuel used) has an open air burn temperature of 287.5 °C (549.5 °F), in the relatively enclosed space the temperature could be potentially much higher, easily enough to bend steel, the stresses caused by this will lead to a collapse. Not to mention, the aircraft aluminium can potentially react with rust on the beams, causing a thermite reaction.
