Those two paragraphs are at odds with one another, no? Moving air also increases the evaporation rate.
This is why fans are found to be generally effective to 104 degrees. https://time.com/5644737/fans-can-make-you-hotter/

The OP goes through a lot of evidence saying the threshold is lower.
I’d replace top with something like: A fan isn’t directly helpful, unlike an AC it’s not going to cool an empty closed room. However, it can make a wider range of temperatures and humidity levels comfortable through aiding evaporation or bringing in cooler air when possible.
This is why as the article mentions a fan alone can be worse than doing nothing in sufficiently hot and dry air. People only sweat so fast so at some point without supplemental moisture the fan acts like a convection oven simply warming people faster. This can be offset by adding supplemental moisture via a 'evaporative vests' or mister the maximum temperature increases.
This and other reasons mean health organizations are concerned with finding and communicating the maximum temperature fans are still useful.
