The parts book shows a different fan for 54th Series with AC, but it is the same fan specified for all 24th-26th-25th Series cars ('51-'53).

That larger fan was implemented, per STB 51T-30, as an upgrade for 24th Series models with low speed cooling issues, but apparently became standard issue from then on - until 54th Series.

Nothing listed specifically for 26th Series ('53) cars with AC, but I would assume that the stock fan would be sufficient - since it was used on 54th Series cars with AC.
