  Clusters of galaxies are outstanding laboratories for understanding the
physics of supermassive black hole feedback. Here, we present the first
\textit{Chandra}, Karl G. Janksy Very Large Array and \textit{Hubble Space
Telescope} analysis of MACS J1447.4+0827 ($z = 0.3755$), one of the strongest
cool core clusters known, in which extreme feedback from its central
supermassive black hole is needed to prevent the hot intracluster gas from
cooling. Using this multiwavelength approach, including 70 ks of
\textit{Chandra} X-ray observations, we detect the presence of collimated
jetted-outflows that coincides with a southern and a northern X-ray cavity. The
total mechanical power associated with these outflows ($P_{\mathrm{cav}}
\approx 6 \times 10^{44}$ erg s$^{-1}$) is roughly consistent with the energy
required to prevent catastrophic cooling of the hot intracluster gas
($L_{\mathrm{cool}} = 1.71 \pm 0.01 \times 10^{45}$ erg s$^{-1}$ for
t$_\mathrm{cool}$ = 7.7 Gyrs); implying that powerful supermassive black hole
feedback has been in place several Giga-years ago in MACS J1447.7+0827. In
addition, we detect the presence of a radio mini-halo that extends over 300 kpc
in diameter ($P_{1.4 \mathrm{GHz}} = 3.0 \pm 0.3 \times 10^{24}$ W Hz$^{-1}$).
The X-ray observations also reveal a $\sim20$ kpc plume-like structure that
coincides with optical dusty filaments that surround the central galaxy.
Overall, this study demonstrates that the various physical phenomena occurring
in the most nearby clusters of galaxies are also occurring in their more
distant analogues.
