Sure, I put some 1mm or 1.5mm thermal pads on top of the SSD controller which makes contact with the input cover sinking the heat from the controller.
I posted a picture here where you can see the repurposed thermal pads I used (hence why they are in 4 pieces and a bit messy) half the thermal pads stayed stuck to the input cover (bottom middle of the picture) and the other half stayed on the SSD controller (the far right square on my SSD).
