I got 2x fans from old ATX PC case. Not sure if they were for the processor or just cooling fan in the case.
They are quite small, and each has red and black cable coming out from the core, and it says on the fan 12V.
So I connected them to my PSU, and turned to 12V. But no action. The fans are just still, not moving.
I got my DMM and checked resistance of the red and black cable, and it reads 10M ohms. Both are similar resistance.
Are these fans dead? Or what? Why are they not working with 12V supplied to them. There is no switches, just two cables from the fan.
