Yesterday my CPU temps read a chill 40 degrees. Today, the fans are pumping full on, I'm still above 4 ghz (skylake) but the the BIOS temp and my mobo software temps readings are in the red, 100 degrees Celsius. I've been ok for the past 2 days (newly built PC) and everything was fine until today. Anyone got ideas on what's going on? (I'm running a 2015 bios, but since it was ok the past 2 days i'm thinking thermal paste, cooler, and dust as well as electrostatic discharge are improbable. The only real thing that pops to mind is the temp sensor got all messed up, although that is also improbable).
