It depends on the size of the resistors (actual size, not ohms rating). I used large 500 ohm resistors. But, just to be sure I'll run a load on it. I have a infrared Lazer gun. I'll shoot the temp at the start and every 30 minutes for a couple of hours. Heat is always a byproduct of energy, so I wont be surprised if it heats up a little bit. We'll see what the result is.
