According to an example, a socket to support a first board in a spaced relation to a second board may include a base section having openings to receive connectors that are to electrically connect the first board to the second board. The socket may also include a plurality of walls extending from the base section, in which each of the plurality of walls is angled with respect to the base section and in which the plurality of walls include air ducts to enable air to flow through the socket when the first board is positioned on the socket. The socket may further include socket alignment elements extending from the base section, in which the alignment elements are to be inserted into mating holes in the second board.
