I used a 24V brushless DC fan with 12V panel, 48V brushless DC with 24V panels (two 12 in series)
With brushless DC you are taking a chance if Voc of panel exceeds rated voltage of fan. Even Vmp of a "12V" panel is about 17V.
If brush type (no electronics) not so much risk.
But if 12V brushless is cheap and available, you can try your luck.
