Tech help: weird laptop problem

[cdcox]

I dropped my laptop yesterday. It was in its case, and the strap failed and fell from the height of my hip.

Now it has this strange overheating problem. Both fans will start running and won't stop. The air coming from one fan is warm, the air coming from the other is cool. Its like there is a poor air circulation problem or something.

Very minimal CPU is being used, so it isn't that.

Any ideas what is going on? Is it worth opening the case and taking a look around?
