FrostyTech has posted a review on the AVC 117160 Socket 478 Heatsink
Along with the stainless steel mounting clips which actually fit overtop of the 117160, and the Heatsink Retension Mechanism (HSRM) AVC have included what we'll call a PCB backplane support. AVC call it the X-Pad. Basically, it is an X shaped piece of metal that fits behind the PCB. The HSRM screws into this device which supports the tension of the heatsink and stops the PCB from bending too much. If you have the chance, mount the regular Intel socket 478 heatsink onto a motherboard outside of the case and take notice of how much it bends the PCB. Pretty bendable eh?Read more
