No, as long as you make sure to attach the heatsink to the label on top of your P5 Plus and NOT to the bottom label that reads “Removing this label will void warranty,” your Crucial P5 Plus warranty will not be voided by the heatsink or by installation in your PS5. For information about your PlayStation 5 warranty, please consult Sony’s warranty terms.1.Sony recommends that NVMe M.2 drives installed in the PlayStation 5 should be used with a heat-dissipation mechanism, such as a heat sink or heat transfer sheet. Inappropriate use of a heat sink, or lack of heat-dissipation mechanism, may cause problems with the P5 Plus and/or PlayStation 5. Micron is not responsible for the user damaging the PS5 or other material. The Crucial P5 Plus meets the performance and form factor requirements for Sony PS5 when used with a heatsink.
