Dell's "temprature probe has exceeded a non-critical threshold" message

Today I got a call from a user who was receiving a message that read:

"A temperature probe has exceeded a non-critical threshold..."

This message, according to Dell means that either the heat sink [on the CPU] has come loose or a fan is not working correctly.

This issue might be easy to resolve for many users by simply blowing into the fan vents, this could dislodge any dirt that is blocking the fan, which is the most likely issue. If not, you may need to remove the cover and use a can of compressed air or a PC vac to clean out the inside of the computer (remember to unplug the system first!).

If it is a heat sink, you can reattach it with some glue from a PC parts store.

Running the Dell diagnostics will help you to determine which part is not working correctly and lead you to the next step you should take (either cleaning or replacing the fan or fixing the heat sink).
