MacBook Pro fan running constantly

My 3 month old MBP's fan started running constantly a couple days ago, even when I close the lid. My usage is about 90% internet - no CPU intensive games or really anything else.

This happened about the same time my two small children were trying to play with the computer - they had gotten into the Guest account and somehow the computer was locked, so I did a hard power off. Since then (roughly) this fan problem has been present.

I can't find any software settings that would cause the fan to run constantly. Any suggestions? The machine is running very smoothly overall, and has been a bit cooler on my lap (as one would expect I suppose). But it's annoyingly loud and I'm worried the fan will die from overuse.

Any suggestions?

MacBook Pro, Mac OS X (10.7.3)

Jodi, you might try an SMC resetas that seems to help clear a lot of system power related issues.

Just putting the Macbook Pro Retina to Sleep by going the Apple Menu command did the trick. So another thanks for the question and Ralph's pointer to Apple's Knowledge Base article http://support.apple.com/kb/HT3964

And let me say what a bizarre OS or fan glitch that, I guess AS OF DEC 21, 2013, still UNFIXED BY APPLE?

Like Jodi, my MBP is, hmmnnn...3 - 4 months old. And her post was over a year and a half ago. Also, bizarre that Apple has a Knowledge Base article dated from Oct. 2012 so it's clearly known about it for x amount of users...

Even if they solved it in Mavericks, they should still patch and support OS 10.8
