For a twist: Yes, you would follow 3x rule. However, it is likely light hazard with ceiling fan. So, since it is non-structural, do you have to follow it?
I think prudent design is to be the 3x away with QR sprinklers. However, it could be ignored since it is non-structural. I typically see residential or ex cov sprinklers in these situations and that forces you to the 4x rule. Plus the allowance for non-structural is only for standard spray sprinklers.
