Températures max OCCT 1h : entre 60 et 68°. Je précise que je n'ai pas un boitier de grande qualité pour l'instant, je vais me commander le mois prochain le Sniper Storm Black Edition de Coolermaster. J'espère perdre quelques degrés supplémentaires

Pour 4.2 ça chauffe trop, et pour la ram à 2000mhz, j'ai essayé de nombreuses fois, impossible...
