    So I purchased this fan from DFRobot ... ct_id=1520 since I was having trouble with my panda after watching stream services on my TV for a while. CPU throttling and heating problem most likely.

    After I installed the fan it started to run immediately after the lattepanda was plugged in to power even though the lattapanda itself wasn't turned on. So everytime I turn the lattepanda off now the fan just keeps spinning until I disconnect the lattepanda from electricity. Is this normal, is the fan supposed to be working all the time even if the board is turned off?

    As long as there is power on the board your fan will keep on running.

    You could use a transistor or MOSFET as a switch, see this thread
