We study the temperature of rotating probe D7-branes, dual to the temperatureof flavored quarks, in the Kuperstein--Sonnenschein holographic model includingthe effects of spontaneous breakdown of the conformal and chiral flavorsymmetry. The model embeds probe D7-branes into the Klebanov-Witten gravitydual of conformal gauge theory, with the embedding parameter, given by theminimal radial extension of the probe, setting the IR scale of conformal andchiral flavor symmetry breakdown. We show that when the minimal extension ispositive definite and additional spin is turned on, the induced world volumemetrics on the probe admit thermal horizons and Hawking temperatures despitethe absence of black holes in the bulk. We find the scale and behavior of thetemperature in flavored quarks are determined notably by the IR scale ofsymmetry breaking, and by the strength and sort of external fields. We alsoderive the energy--stress tensor of the rotating probe and study itsbackreaction and energy dissipation. We show that at the IR scale thebackreaction is non-negligible and find the energy can flow from the probe tothe bulk, dual to the energy dissipation from the flavor sector into the gaugetheory.
