XMM -Newton RGS observations of the cores of galaxy clusters show much less material than would be expected from a simple cooling flow picture. Deep observations do, however, show that cool X-ray emitting gas does exist and there is a wide range of temperatures in many clusters. By examining deep RGS and Chandra observations of cluster cores we examine the nature of this very cool gas. We discuss the implications for AGN feedback in these objects and show that the coolest gas must exist in the form of cool blobs in a hotter medium.
