      The other factor that affects this question is how fully loaded is your Altair? With a very lightly-loaded Altair, the input voltages to these regulators is higher, and the regulators will get hotter.

      If it were mine, I would not add the resistor. The card will work fine without it - maybe the regulator will get a little warmer with extended use.

      The 7805 regulator has a thermal shutdown circuit, so even if it gets too hot, it will just go into shutdown, without damage. :-)
