  Extremal black holes have vanishing Hawking temperatures. In this article, we
argue that for asymptotically AdS black holes, at extremality, a particular
class of correlators in the dual CFT can exhibit exponential, maximally chaotic
growth with a non-vanishing temperature. Our approach, at extremality, is
two-fold. First, we geometrically investigate the modes that are responsible
for chaos. Secondly, we study the dynamics of a probe string to capture chaos
in worldsheet correlators. For rotating BTZ at extremality, the corresponding
Lyapunov exponent is determined by the left-moving temperature. In higher
dimensional AdS-Kerr geometries, on the other hand, the corresponding Lyapunov
exponent becomes a non-trivial function of the Frolov-Thorne temperatures.
