I am gradually building my new computer (I have only three components remaining to purchase: the video card, the power supply, and the motherboard), and I have several fans that I shall be adding to its case, but I wish to test those fans without needing to connect them to my computer, as doing so would be a major hassle and my current case cannot fit the 200 mm fan that my new case shall be able to.
Therefore, does anyone here have any recommendations on how I can test a fan without needing to connect it to my computer? Can I simply use a battery and attach a wire from each of its terminals to the prongs of the fan connector, or is there a better method than that? Thank you very much.
