The integrated heatsink helps to enhance performance by quickly dissipating heat to provide longer sustained speeds. The 990 PRO SSD and heatsink are designed to fit into desktop and laptop systems that comply with the PCI-SIG D8, 8.8mm standard. It can also fit in the Sony PlayStation 5. The heatsink has RGB LED lights to add style to function.
