We study extremal and non-extremal generalizations of the regular non-abeliansolution found by Chamseddine and Volkov in 5d N=4 gauged supergravity, whichhas been shown by Maldacena and Nastase to describe a system of NS5-braneswrapping an three-sphere dual to three-dimensional U(N) N=1 supersymmetricYang-Mills with Chern-Simons coupling k=N/2. All black hole solutions have atemperature larger than the Hagedorn temperature Tc of the little string theoryand their entropy decreases as the temperature increases. This is a sign thatthe system is thermodynamically unstable above Tc. We have also found ananalytical solution describing NS5-branes wrapped on a constant radiusthree-sphere and involving a linear dilaton. Its non-extremal generalizationhas a temperature equal to 2 Tc.Comment: 27 pages, 6 figure
