Install iStat Pro to get accurate readings of temps and fan speeds. It's better to know what temps you're talking about, as they're likely normal.

Also, you may have better success in attracting responses to your thread, and you'll make your thread easier to find for those browsing the forum for the same answers, if you follow this tip.

 

Welcome...
When posting provide as much info as possible (the issue, when it occurs, what model is it, operating system, etc.) Generally if people want more info they will ask.

Macbook Pro's and all of apple's notebooks get warm as the aluminium acts as a heatsink- but don't worry; they are designed to shut down before they over heat.
They get warm when doing processor intensive stuff like video calling gaming, and viewing flash content.
smcFanControl is an application that controls the speed of the fans and thus, lowering the overall temperature of your mac. It lowers the temperature by drawing more cool air.
Your mac will raise the RPM of the fan when it senses it gets to hot- there are internal thermometers.

Hope I helped.
