Hi Domenico,
Those Paca temperatures are within the operating range but yes, if it's hot in your studio (or if you go somewhere to perform where it's hot), it's a good idea to enable maximum case cooling. (Whether to enable the always-running fans is more of a personal preference; it is probably not necessary, but you can enable it if you prefer it that way).
(Hope you have some fans on yourself too — stay hydrated!)
