  We study the current correlations of fractional quantum Hall edges at the
output of a quantum point contact (QPC) subjected to a temperature gradient.
This out-of-equilibrium situation gives rise to a form of temperature-activated
shot noise, dubbed delta-$T$ noise. We show that the tunneling of Laughlin
quasiparticles leads to a negative delta-$T$ noise, in stark contrast with
electron tunneling. Moreover, varying the transmission of the QPC or applying a
voltage bias across the Hall bar may flip the sign of this noise contribution,
yielding signatures which can be accessed experimentally.
