So i just built a custom rig, asus maximus vii hero, gtx 980, corsair 450d case, and the corsair h100i cooler. My idle temps are around late 30s to mid 40c, my cpu voltage is 1.1v. I'm not sure if it's an airflow problem or it's not mounted correctly, i've tried a few times all giving me the same numbers. Any suggestions on how to lower temps?
