'non-noetic' originates from English, specifically the prefix 'non-' + the adjective 'noetic', where 'non-' meant 'not' and 'noetic' derived from Greek 'noētikos' (from 'noēsis') meaning 'intellectual' or 'of the mind'.

'noetic' comes from Greek 'noētikos' (from 'noēsis'), passed into Late Latin/Latin-derived scholarly vocabulary and then into English as 'noetic'; the negative prefix 'non-' (from Latin 'non') was later attached in English to form the compound 'non-noetic'.

Initially, 'noetic' meant 'of or relating to intellectual/mental activity'; 'non-noetic' therefore developed to mean 'not relating to intellectual or intellective activity' and retains that negative relation in modern usage.
