Hi Andy,
95 is much too hot, you want to keep the xtemp readings below 70 or as close as possible. By any chance are you running your board inside a case or other enclosed space? The heat sink, _any_ air-cooled heat sink, is only good at transferring heat to the surrrounding air and then the hot air must be replaced with cooler air. This replacement can happen by convection or be forced by a fan, but if there is nowhere for the hot air to go it will just continue to heat up. The large heatsinks are only "fanless" if operated in the open, any enclosure will require a fan. HTH
