so I left my window open in my small dorm room and my PC running not realizing how cold it was and now my cpu was idling at about 5 degrees C and my GPU at about 10, according to open hardware monitor, my question is are these temps dangerous, they were left in the cold room for about 2-3 hours (I was in class and in town). I've never hit this low and it kinda worried me. I'm using an i7 4770K and a reference 780ti.
