Current strategies to modulate HC dynamics often compromise intrinsic material properties or introduce competing photophysical processes. Here, we demonstrate that long\u2010range electronic coupling in CsPbBr\n                    <jats:sub>3<\/jats:sub>\n                    supercrystals (SCs) efficiently accelerates HC cooling across different excitation regimes, enabling cooling dynamics approaching the prediction of the longitudinal optical phonon model. Owing to enhanced electronic density of states arising from cooperative interactions, transient absorption (TA) spectroscopy reveals SCs enable HC cooling that is twice as fast as isolated nanocrystals (NCs) at low carrier densities (2 \u00d7 10\n                    <jats:sup>17<\/jats:sup>\n                    cm\n                    <jats:sup>\u22123<\/jats:sup>\n                    ).
