I am a bit concerned about the weight/length of the heatsink in a tower (vertical) installation (X9DA7 + SNK-P0050AP4). Can you please confirm that the weight of the unit will neither cause a premature failure of the mounting hardware to the MB, nor abnormal pressure on the top of the CPU?
Our Super Workstation has passed system level drop tests. So, SNK-P0050AP4 heat sink weight is not an issue.
