Temperature limits for turbine engines are something to be aware of - the same as any engine, gearbox or airframe limits. Start up is when you should be most attentive as this is generally when you will see temperature peaks - particularly if the engine is already hot. If it is and you are able then a vent is your best bet. Depending on your operating environment you will find that during flight the torque and N1 are your first limits.
Welcome to the turbine world - you'll find life much easier.
