    I am having a problem with a 12V DC axial fan cutting out under load. By load i mean blocking air flow. I am using this fan as a test bed of free air in different panels. I am under the assumption that the increased load on the fan causes it to draw to much current at start up. Once the fan reaches max rpm with no back pressure on it, it runs fine when you put the panels in place.

    equipment: 12V DC fan 2660 mamps 32 watts. 12V 3.5 amp/hr sealed LA Battery.

    Is it as easy as putting a resistor in line? If so what size and power resistor should I use?

    Thanks in advance
