'''3.''' Remove the blue protective sheet from the 3 smaller pieces and stick them to the inner side of the thermal block, the one that makes contact with the RPi4. You'll recognize it because it has 3 small rectangular islands that fit the size of the 3 smaller pieces you cut out. You can use your finger to press the thermal pad and stick it. Use your fingernail to cut off the excess, if any.

'''6.''' Finally, stick the remaining piece of thermal pad (27 x 20 mm) on the contact surface in the external side of the thermal block. That is, on top of the "tower" with 2 tiny holes. Follow the same procedure you already did with the 3 smaller pieces, but don't remove the transparent protective sheet yet.
