Running operating system 10.11.3 (15D21)
My fan is running at a high rate of speed. Not sure why?
Run an Apple Hardware Test or Diagnostics, whichever is applicable:

It would be helpful if you indicated the EXACT model/year MBP that you have.
Ciao.
This is what I got after running the diagnostics.
It is showing a Hard Drive or SATA cable error.
You can Try resetting the SMC http://support.apple.com/kb/ht3964
You can do a simple test by booting off a external bootclone to see if the problem is gone.
Are there other gross symptoms besides the fans on highspeed?
It still might be helpful if you indicated the EXACT model/year of your MBP.
Ciao.
Thank you for the help! This seems to have solved my issue.
