Anyway To Overclock Dv6?

About 10 months ago I ordered an HP pavilion on amazon. Without really looking up the specs I would need daily. I'm not a hardcore gamer but I really enjoy playing S4 league and Forsaken World. Well within 4 months I noticed something was wrong with the cooling fan so I kept it for a while as is. Then I sent it to HP for the warranty thing the other day. Another reason I why I decided to send it back for repairs was. The fps went from 62.5 (max fps for that game) and started spiking down to 40ish on s4 league. For the last 10 months it would get hot and loud and such but never affected my fps for anything. So while it's getting fixed I decided to look up ways to improve it. And it seems overclocking is pretty effective. They say it's not safe to overclock a laptop because it'll heat up quicker. What I was wondering was when you over clock it, and let's say the CPU is 2.4GHz and would go up to 3ghz with overclocking. Is it running at 3GHz all the time even during idol stats or simple tasks? Like basically whenever it needs more than 2.4 GHz it'll start using more? And if not then if let's say I take it to class to take notes with or surf the web. It won't heat up because it wouldn't be using 3GHz right? And let's say if I did need 3Ghz, if I use a cooling pad like the Cooler Master NotePal X2 Laptop Cooling Pad with 140mm Blue LED Fan (R9-NBC-4WAK-GP). Would it somehow help cool it down?

I'd like to know if my netbook would be overclock able or not. And if possible how exactly to achieve such an epic achievement? @_@. I'm not sure how exactly to present the specs so I'll provide the link of the laptop if that will help. If it isn't realistic at all I'll understand. I actually plan to invest on an assembled computer in a year or so. That I'll put time to study and get the best parts I can. But between now and then I only have this netbook, so I'd like to get out as much as I can off it within the year.
