It didn't need to be hot enough or long enough; The fire didn't disintegrate the towers. A huge amount of the support was missing, and it failed to support the floors above the impact zone. Keep in mind here that at the moment of impact, entire floors were destroy. Eventually, the floors above the impact fell because the support at the impact was either gone or weakened.

The fire was in fact fueled by tens of thousands of jet fuel. I'm sure it burned off in ten minutes of jet fuel is enough to make that a burning inferno.

The fires burned from impact until the towers fell. Stop making it sound like "some office furniture caught on fire". Fifty thousand people worked in those towers; There was enough fuel in the towers to keep burning for weeks.

Clearly you've never been to the WTC when they were standing. The lobby is huge, massive, four - six stories tall, and for the most part all stone, marble, granite, concrete, and steel. Yes, the fireball that shot down to the lobby quickly burned itself out. There wasn't much of anything to catch on fire in the lobby.

Doesn't matter. It was enough to damage what was left of structure to cause it to fail.

No, it wasn't a "relatively small fire in comparison with building size". Entire floors were missing form the building, and dozens of floors were instantly on fire.

Re-read what you wrote here and try hard not to laugh.

From
Wikipedia article....
"While calling for further study, FEMA suggested that the collapses were probably initiated by weakening of the floor joists by the fires that resulted from the aircraft impacts".
Then....
"NIST also emphasized the role of the fires, but it did not attribute the collapses to failing floor joists. Instead, NIST found that sagging floors pulled inward on the perimeter columns: "This led to the inward bowing of the perimeter columns and failure of the south face of WTC 1 and the east face of WTC 2, initiating the collapse of each of the towers."

Not at all. The buildings both had the exact kind of damage - a large airplane destroyed most of the support structure, fires in both buildings weakened the towers, up to the point where the impact zone was unable to support the floors above it and then it all fell down.
Take a look at this picture:
It looks to me like the entire side of the building is gone for four - eight stories. It's stunning that the towers were able to continue to support it's weight for as long as it did. And keep in mind here, that's only the damage we can see.
