I'm new to raspberry pi and decided to start off with the slightly older version, the model B. After plugging it in, it takes it about 5 minutes to heat up. It reaches about 60 C. It is supposed to only reach 40 C. I've already ordered some heat-sinks and a fan. What are the reasons it's heating? Thankyou

    What sort of temperature are you talking about? Run /opt/vc/bin/vcgencmd measure_temp – joan Oct 1 '15 at 13:02

    Ditto. It is normal for the processor to be warm to the touch, ~40°C when idle. The manufacturer has said it should not require any cooling regardless of how you use it (with the exception of overclocking). Even maxing it out continuously, the processor will not get over ~60°C, I think. – goldilocks Oct 1 '15 at 13:37
  • Thanks! I think I'll be the fan anyway, they're relatively cheap. – A.Murph Oct 1 '15 at 13:43
  • It's at 43 celcius – A.Murph Oct 1 '15 at 13:47

    Okay, so in fact it is not overheating...it's at normal operating temperature. Some people just like fans -- I think it is the white noise factor ;) – goldilocks Oct 1 '15 at 14:10

43C is normal operating temp for the pi. I also have this model and when I bought my case it came with 2 aluminum stick on heat sinks mine stays about 2-3 degrees cooler with them. I also OC mine and it still operates within normal specs.
