  This communication describes test beam results, focusing on detection
efficiency and timing precision, of common float glass timing Resistive Plate
Chambers (tRPCs) exposed to a $2.7$~GeV proton beam and operated at above
ambient temperature in order to increase the count rate capability of the
chambers, by exploiting the reduction in the resistivity of the glass
electrodes. Results suggest that the count rate capability can be extended at
least up to $1500~Hz/cm^2$ when the detector is operated at $40.6^{\circ}$C
without noticeable loss of efficiency or timing precision degradation with
values of $90\%$ and $100$~ps, respectively, for this specific timing RPC
arrangement.
