After a landing 20 KTS above reference speed using 'lo' autobrake setting, maintenance reported a brake fire even though brake temperature indicated 280 degrees below the required write-up temperature.

Narrative:
On visual approach to runway 28R (asked for runway 28L) briefed both approachs. Cleared for visual to runway 28L. Ended up a little high for runway 28L since it was closer. No problem since it is 11500 ft long. Decided to use 'lo' on autobrake. Touched down and did not use brakes until turnoff at end. After parking, brake temperature started to rise and I left the parking brake off as chocks were in. After doing parking and security checklists and heading for home, I was told by a mechanic that there was a brake fire. We checked the book together and decided that the parameters were not exceeded to cause a write-up in the log. Supplemental information from acn 480695: I checked the manual. Brakes got to 620 degrees and manual said write-up was required if brakes got to 900 degrees.
