High temps aren't really the problem. It's the winter lows that can cause difficulties. I assume, as you've put zone 8b in your details, your temps get down to 15F hence why I assumed you'd be growing your other cyms in a greenhouse of indoors. All 3 of the Australian species are warm tolerant. As far as winter, Cym suave is the most cost tolerant and mine take take brief temps down to 32F. While I've had Cym madidum take temps down to 32F they can go backwards if you're not careful about the watering. A bit more warmth in winter will definitely make it happier. Cym canaliculatum prefers warm to intermediate conditions although as others have said this species favours drier conditions and low humidity especially in winter. It can take winter temps into the 30's but you have to keep it very dry to avoid it rotting.
