Slide the flat end of your Framework Screwdriver under the heatsink arm labeled "2".

Gently twist the Framework Screwdriver to lift the heatsink arm and loosen the heatsink.

You'll feel some resistance from the thermal compound holding the heatsink in place. Stop if the heatsink arm begins to bend.

If the heatsink won't budge, make sure you've fully loosened the four screws securing the heatsink.

Repeat the procedure with the heatsink arm labeled "3".
