Answer:
FALSE
Explanation:
The preposition "from" usually indicates origin, that is, the place where an action starts. For example: I come from Brazil. / This gift is from grandma. / I saw her from my window.
In the sentence, we do not need to indicate origin. We need a preposition that will help us convey the idea that we used a tool - a fan - to do an action - to cool ourselves. In this case, I believe the preposition "with" would be the best option:
I cooled myself with a heart-shaped fan.
