Designed to replace the OEM bottom plate on all unibody mac mini models (excluding 2014 variants). This new bottom plate was designed to increase internal airflow to help better cool the CPU and other important components. The plate will also still protect all internal components, something an open case will not do (which is a popular way to increase airflow and cooling)
To install simply twist to remove your OEM plate and then twist to lock this new cooling plate on! OEM locking and fitment.
