I already have the mainboard. You can remove the Corsair Heatsink without much effort and, according to Corsair, the warranty remains valid. Installed in the board, the SSD with the mainboard heatsink runs at approx. 60 to 65 C under full load. Idle at 45 to 50 C

...if the heatsink is removed, but would buy another from Samsung Evo or Pro.
