But it is good to leave some space for airflow. Mind air for iunlock's VRM cooling should enter via the gap above the heatpipes, leave via the small central grille, and meanwhile go past the heatsinks and the copper foil. You can use a file or sand paper to reduce the size of the heatsinks, if you think they are too big. It will be difficult to find something smaller. AFAIK small copper heatsinks for mosfets with nail-like fins exist, but you'd have to trim those too.
