📏 M.2 Size & Heatsink Clearance Advice

Most laptops in the Lenovo IdeaPad 3 family accommodate standard single-sided M.2 2280 (22mm wide by 80mm long) SSDs.

Important Installation Tips:

Avoid bulky metal heatsinks: Notebook chassis tolerances are extremely tight. Purchase bare M.2 drives without tall pre-attached aluminum fin heat sinks. Graphene heat spreaders (like Samsung 980 / WD Black SN770) fit perfectly.
Single-Sided NAND Only: Dual-sided SSDs (chips on both top and bottom) may bend or exert pressure against bottom motherboard SMD components. Always choose single-sided SSDs.
PCIe Gen4 Backwards Compatibility: If your slot is PCIe Gen3, a Gen4 drive will operate at Gen3 maximum speeds (~3500MB/s) without temperature or boot issues.
