The Vanquisher comes ready to mount to LGA775 sockets. To mount on AMD systems, the LGA775 brackets are removable with four small Phillips screws. The screws were challenging at best to remove. After a half hour of trying various screwdrivers that were too big, jewelers screwdrivers that could not generate enough torque, and mangling the fins numerous times, the LGA brackets were finally freed from the Vanquisher's hold. The only casualty from the entire affair was the pre-applied thermal interface paste OCZ had generously applied.
