Just my 2 cents - not knowing this very specific adapter (but being notified of our original post):Does this adapter have screw-holes to screw it into the tray?
1. This drive is SAS - and thus probably not relevant for laptops (but perhaps the "laptop" in the post was a mistake??)
2. They do get warm if not cooled (actually the will become "too hot"!) - so if in a case and/or laptop with limited airflow it is quite important that the adapter can transfer heat... Not only touching the drive, but perhaps even with some heat transfer medium (tape, paste, whatever)..
In my server I printed a bracket for another adapter - that holds 2*4 drive directly in the path of airflow - they rarely go above 40C, but without proper cooling they easily reach their threshold of 65C..
