Are you Frying an Egg, or cooling your laptop?

As a general guideline, these temperatures are really the maximum I would consider safe for a laptop…

  • 0-104F (40C) = Cold.
  • 122F – 158F [50-70C] = Typical-ish use, still safe.
  • 159F – 185F [70-85C] = Heavy use, consider moving to flat surface, elevating, or cooling it.
  • 185F+ [85]+ = Hot! Go take a break.

If you laptop (or desktop) is running hotter than that, then double check to see if there is dust buildup in the cooling system.  Is there anything around the air inlet’s that would be blocking them?  Shag carpet?  Fluffy lap blanket? etc…

Long answer: the highest temperature the internals can handle depends on the manufacturer and model. Unless you feel like opening the laptop up, your best bet is to do the following:

  • Find the CPU model by looking at the System Information screen or via System Information.
  • Google for the datasheet. For instance, if it’s a P8700, you would google for {P8700 datasheet}.
  • Download and open the datasheet. Look for a section named something like “Maximum Ratings”; this section will have either a maximum storage temperature or a maximum running temperature.

Alternately, you can try finding it in this list, but it’s a bit out of date.
