Abstract: We present non-extremal generalizations of N f=2N c supergravity dualsobtained by adding flavor branes to the Chamseddine-Volkov-Maldacena-Nunezbackground and taking their backreaction into account. For a particular rangeof parameters we obtain a one parameter family of analytic black hole solutionswith regular horizons. These solutions have a temperature that is always abovethe Hagedorn temperature of little string theory. We find that including flavorbranes and their backreaction increases the minimum temperature of thesesystems from T = 1-4\pi, for the background without flavor, to T = 1-2\pi\sqrt{1 + epsilon}, epsilon << 1. We show that outside the range of validityof the analytic solutions presented here the backgrounds have nakedsingularities.
