Ho to test /trigger HV battery fan

I just cleaned my fan and want to test it, it's kind hard to hear it, I learned that there are 3 speeds for fan,
Right now I start driving with outside temp and on the peak have 104-107F with outside temperature 85.

Is this good indication that fan is working ?
Or maybe I can try to see if any flow inside vent, with smoke ?

Thanks PriusCamper,
this is too simple test, I tested fan after cleaning on my lab power supply, it's working .
But when you hook it into the car, it wont' run all the time, need bright temp higher, and then it's still hard to see/hear anything.

Do you think it should run when PriusDoctor shows 105F?
