|With care the fan is removeable. It would be harder if the heat sink is removed. Leaving it attached would be a third hand to hold the assembly while you work. I think jewelers screwdriver, a small knife edge and maybe a few toothpicks would do. A needle nose pliers that can fit the depression would work. I would use small pieces of tubing to hold the fingers in.|
For those with fat fingers, replacing the fan and heatsink is a better choice. You have to remove the clip. Usually you depress te end of the clip slightly so you can release the end. Don't forget to install the thermal paste or pad when you reattach.
