My fan is running really loud, low cpu (i think?)

Question

My fan has been running really loudly for a day now. I have tried turning it off and on again, putting it to sleep, cleaning out the dust.
On my activity monitor "opendirectoryd" is running at 94.5 percent and I have no idea what that is and if it is causing the problem?
I have looked at answers on other forums for the same thing but none of the remedies have seemed to work. Can any one help please?
I also put in some code that was on a different forum into 'terminal' but have no idea what the results mean. I have copied it below:

Hi..
Try Resetting the System Management Controller (SMC)
As a rule it is not a good idea to run Terminal commands unless you have a better understanding of what the results should be.
