I think it is simply because on most M.2 drives, it is the bare PCB with chips on it. The standard 2.5" SSD comes in an all aluminum casing, but inside, looks much similar to an M.2 drive. The Aluminum casing acts as a heatsink for the drive. 2.5" SSD's are usually mounted in space, either hanging in the air or at least relatively distanced from other hot parts.
Most M.2 slots find themselves rather close to the CPU socket and Primary PCI-E graphics card slot. When a hot graphics card and a hot cpu are surrounding that little piece of hardware, it can't shed its heat very effectively and may even take on more heat from those components. There typically is reduced air flow because of a large heatsink and graphics card also, and so there won't be direct airflow onto an M.2 drive unless there happens to be a side panel fan pointed at it. Oh yeah, and the motherboard itself generates heat too, forgot to mention that.
My opinion and some thermal dynamics. Edited by Bigceeloc - 7/25/17 at 6:02am
