Yeah 50-60 is getting into the too hot area. The problem is probably that the IHS has been removed. The A64 Cooler pro is designed to clamp down onto a CPU with the IHS fitted, but as yours does not, the CPU will be thinner, so the heatsink will not be making decent contact. You have several options of how to fix this; Buy a new cpu, Reattatch the IHS or buy a Cooler with screw mounts, which allows you to tightne it as much as you want(If you do go down this option, be carefull not to crush the core though.)
