    So I bought a case from someone off of craigslist but it didnt come
    with rear fans. How can I tell which size i need

    Compare it to the power supply fan...

    If it's the same, that's likely 80mm if it's bigger, that's likely 120mm

    Lord Garth Inscribed thus:
    I would also ask the question "Do I really need a fan" ! An awful lot
    of the time you do but not necessarally at the rear of the case. The
    PSU fan is very good at extracting heat from the top of the case. Its
    the hot spots that you should target with an additional fan !

    Try to find a ball bearing fan as opposed to a sleeve bearing. These
    will run quiet for longer. Nidec makes good fans.
