The M.2 heatsink’s EZ-Latch design features a metal clasp at its front. By pulling on this clasp, the heatsink can be opened. Inside, the M.2 SSD is also secured using the same EZ-Latch system. Thanks to a spring-loaded mechanism, the SSD can simply be slotted in and pressed down to lock it into place, eliminating the need for tools and simplifying the installation and removal process.

The motherboard’s first M2C_CPU slot operates on the CPU’s PCIe 5.0 channel. As a result, once an SSD is installed there, the bandwidth of the first PCIe slot is reduced to x8. Moreover, to accommodate PCIe 5.0 SSDs, the height of this particular heatsink set has been increased, offering significantly enhanced heat dissipation capabilities.
