1.5-Inch 24V DC Cooling Fan (40mm)

This fan shares the same 40mm footprint and mounting pattern as its 12V counterpart, but is wound to run directly off a 24V supply instead, which matters for projects built around the 24V rail common in industrial automation equipment, PLC systems, and higher-voltage battery setups where stepping down to 12V just to run a cooling fan would be an unnecessary extra conversion stage. Keeping both voltage versions in stock means a builder can match the fan directly to whatever rail their project already runs rather than adding a separate voltage regulator just for cooling.
