Will placing a heat sink be beneficial to the SN550 500GB?

The NAND memory performs better when warm (25 C - 80 C) (source).
The controller’s lifetime is longer when cool.
The NAND has been placed as farly removed from the controller as possible (see FLIR image here).

When you place a heatsink over the entire board (like this one for example),
then you will effectively create a heat pipe from the controller chip to the NAND chip.

Is the reported temperature by the drive, the temperature of the controller or the NAND chip?

@ xabierus What temperatures did you measure before and after placing your heatsink?

Will placing a heatsink benefit the SN550, or does it only make matters worse?
