  An exact fully-localized extremal supergravity solution for N_2 D2 branes and
N_6 D6 branes, which is dual to 3-dimensional supersymmetric SU(N_2) gauge
theory with N_6 fundamentals, was found by Cherkis and Hashimoto. In order to
consider the thermal properties of the gauge theory we present the non-extremal
extension of this solution to first order in an expansion near the core of the
D6 branes. We compute the Hawking temperature and the black brane horizon
area/entropy. The leading order entropy, which is proportional to N_2^{3/2}
N_6^{1/2} T_H^2, is not corrected to first order in the expansion. This result
is consistent with the analogous weak-coupling result at the correspondence
point N_2 ~ N_6.
