how do i remove a cpu heatsink and fan that uses screw pins instead of push pins like the screws would look like regular screws. i just don't want to mess up like i did the push pins and i'm planning on swapping out a pentium 4 cpu for a dual cpu

List the CPU u are planning to get and board model number or system model number (only if u have OEM system).You know the real meaning of peace only if you have been through the war.
