i have a dv9743cl and it seems to overheat. i have found a few things to help with this:
1. on the bottom there are a few vents that have stickers on the inside of them that cover up the vents they are just behind the little covers you dont have to entirely take it apart.
2. if you buy a cage for the bottom of it and let it sit on it that helps a bunch.i use a tray that came from a three drawer filer that has little material and alot of air through

3. a usb fan board and set it under for it.(~12$)
4. a usb keyboard helps to reach the keys.(~12$)
after i did these things it seems it flies! for only ~39$ that is much better then new boards or putes, assuming there hasn't been damage yet, or new boards that are going back again soon for fixing again
kind of weird that the skin on the outside of it is named the dragon coincidence i don't think so**
**even as a last resort instead of throwing it away you can take it apart and drill more air vents in it or just leave the shiny silver cover off
out of the last 8 games i purchased only 2 worked this site will help with that stuff.
