Mise \u00e0 jour du 1 mars \u00e0 9h :<\/strong><\/p>\n

Le probl\u00e8me est confirm\u00e9 par notre second testeur, qui a eu l’id\u00e9e d’utiliser des ressorts plus longs (18 mm au lieu de 14 mm) pour contourner la difficult\u00e9 et retrouver une pression normale sur le CPU.

Actualit\u00e9 originale du 28 fevrier 22h :<\/strong><\/p>\n

\"Image<\/span><\/span><\/span><\/span><\/p>\n

Selon nos informations, les cartes m\u00e8res Ryzen sur socket AM4 vont poser probl\u00e8me avec une partie des dissipateurs CPU annonc\u00e9s compatibles<\/strong>. Certaines plaques arri\u00e8re (backplate), fournies avec les cartes m\u00e8res des grandes marques, et destin\u00e9es \u00e0 visser le dissipateur sur le processeur, utilisent des fixateurs de vis trop longs. Du coup, les vis du dissipateur parviennent \u00e0 leur but\u00e9e de s\u00e9curit\u00e9 trop t\u00f4t, et la pression du dissipateur sur le CPU serait insuffisante.<\/p>\n

\"ImageA gauche, une backplate AM4 typique, avec un fixateur trop haut.<\/span><\/span><\/span><\/span><\/span><\/p>\n

Le pourquoi du comment<\/h3>\n

Nos sources indiquent qu’AMD a communiqu\u00e9 sur l’emplacement des vis de fixation, mais pas sur la hauteur des tiges d’accueil. En cons\u00e9quence, certains dissipateurs et kits de compatibilit\u00e9, exploitant la plaque arri\u00e8re fournie avec les cartes m\u00e8res Ryzen, poseront probl\u00e8me. La solution est d’utiliser un syst\u00e8me (ventirad ou waterblocks) disposant de sa propre plaque arri\u00e8re, ou passer par un mod\u00e8le utilisant des bases de r\u00e9tention classiques en plastique<\/strong>. Pour les autres, rien n’est garanti. Notez qu’AMD nous a pr\u00e9cis\u00e9 que leurs propres dissipateurs \u00ab fonctionnent bien\u00a0<\/em>\u00bb.<\/p>\n","protected":false},"excerpt":{"rendered":"
