I would not bother with a dedicated fan (the thermal controlled fan that is part of the unit should do OK)for the bleeder resisters (if you actually have that specific model #) those two resisters are in series @ 1.5KOhm 5watt each they are there to bleed the input side large caps which are dual 820ufd@250Vdc and should be holding 175VDC (or very close the peak of the sine wave assuming you have 120Vac nominal) all the time - not sure if they are actually needed other than a safety thing for fools that do not understand large charged caps - Kind of like guns which are ALWAYS loaded caps are always charged and can be lethal

Keep us updated as to the exact model number since right now we are only stabbing at things in the total darkness
