I am running a h100i aio with an i7 4790k on an asus rog maximus 6 gene motherboard. A couple months back I sold my gtx 1080 and have left my computer untouched since. I decided to connect my asus hd6450 today to run my monitor and am hit with these error messages. In thr bios the temp monitor said it was idling at 88C and after replacing the thermal compound its dropped to 78C. But the errors still stand. I fear that the pump may have died. But how could it? My computer worked fine before then.
