A754 was observed with RXTE PCA and HEXTE (2-250 keV combined bandpass) in order to 1) constrain the hottest temperature component of its intracluster medium, and 2) find evidence for non-thermal emission from the cluster. From previous observations, there is ample evidence that A754 is the result of a merger event. A super hot component of the gas is expected to exist as a result of hydrodynamical processes such as shocks. We present our results and discuss their implications.
