Alienware 17 Fan Problems

[Blackbirds]

Hello! I got an Alienware 17 within the past few months from a trusted seller. The only problem I have about it is the fans spin, but the laptop gets really hot. This problem is happening when I open up any application, even being on CS is making the laptop hot, and the fans spinning! Does anyone have a possible idea to what is happening? Thank you very much, if you do!

Mods; if this is in the wrong spot, please move it to the right! Thanks!
