I wouldn't just tell the crew members of the temperature, I'd show the thermometer to them but do so in a nice, polite way rather than doing so aggressively.
It puts the matter beyond reasonable doubt that it's warm (most people would see 24C as being warm), and closes off the argument that it may be just you finding it hot.
Have other people been complaining about being hot on your flight too?
