This entire thread doesn't make sense. Why?
Because unless everyone measured their temps in the exact same manner, and everyone had the exact same motherboard/mainboard, the temperatures measured wouldn't be comparable at all! Different motherboards have different biases on the temp measurement and different temp-monitoring applications wont always interpret the data from the motherboard in the same way. Some apps will report a temp that is slightly higher or lower than what the real temp is and some just spit out a number that doesn't make sense.
Unless you're running some fancy peltier-cooling or compression-cooling, your temps are always going to be a few degrees higher than the ambient temp (temp inside case).
There's no way you can have a CPU (or any other component) running at 13°C unless your case temp is lower than 13°C and since the temperature inside the case is almost always a few degrees higher than the room temp, your room temp would have to be well below 13°C.
I've had temps as low a 18°C on my CPU (read by manufacture provided software), but that's impossible or the room the comp was in would have been very chilly considering my case temp was around 5C above room temp.
