To test a 12V DC brushless fan, connect +12V and GND to
the two appropriate wires.
You can use a slightly lower voltage, and the fan will
still spin. I use a 9V transistor radio battery and a battery
clip with two wires on the end. That is suitable for a quick
test of lower amperage fans (maybe 100mA type).
My largest fan draws 12V @ 1A, and to test that, I'd
need to use my 12V adapter.
A brushless DC motor, has a small circuit board, which
commutates the voltage as the fan spins. As such, it is
pretty difficult to test from the outside. It's not
like doing some kind of windings check, on an AC motor.
Just apply a voltage and test it, is the best.

I lick my fingers, which is a procedure not to be done by sticking
four, at the most, five fingers into the mouth's oral cavity. Three
fingers will do well enough for placing the wetted side of the fingers
closest an opaque fan air filter covering, to sense coolness from fine
hair follicles on the backs of the fingers when the fan is collecting
cooler outside air to differentially move to within the enclosure.
Besides, it may be only about feeling good should one's tongue be so
placed and out, given a disassembled and better PS already had
replaced ordinarily case fan failings with its ineffably better PS
fan. That's what I did, inasmuch to confess to stub behavioral
modifications evident as a residual for licking my fingers.

Touch the heat sinker. Feel hot your fans has no effect on dissipating
heat.
