I've got a 4 months dv7, and it overheats badly

Question

it is not dirty, and to be sincere, i think it's vent system was very poorly designed, and warranty does not apply because the computer is not broken, but i bought a quite high performance machine just to realize i can't use it. Some people recommend to use an external fan system under the laptop, but then what sense does it make to have a portable pc? to be sincere i want a replacement for a flawless model, but i guess it is too much to ask.

Hi guys and gals
Guess what I have a DV7 4180ea Laptop as well. I had to send it back under warranty to have the beats audio system replaced, it took about a week for them to fix but all seemed ok when it returned. They did a bios update when it was in as well. It was returned to me back in the as new state (all software reset to start) so good job I backed it up before it went in for repair. About a week went past and i noticed it was overheating slightly when I was working the processor at moderate loads (I'm a music composer and use virtual instruments). I had looked at all these post and many others as well so I was not to concerned at the time as mine did not seem to bad.
HOW EVER now mine has just come out of the warranty I was using it the other day and i noticed that i could not touch the left side and there was a scorched mark in the work top that the laptop sits on, (laptop has sat in the same place for about 6 months and constantly on). So I phoned hp c/s and got nowhere, I was very disappointed.
So not being afraid of taking thing apart I thought I'd give it a go.
There are some videos on youtube but nothing I've found is close to what I had to do to get inside(what a work up) after striping the laptop down and getting the main board out there are 4 screws holding the cooling fan to the heatsink even before you strip this off you can't see anything wrong.
Take the fan off and clean the heatsink air ways then put everything back together being careful with the cables reboot the system make sure everything works.
My DV7 now runs under heavy load at 41oC with no problems
Having looked at the way the heat sink works I think you should be able to remove this dust and fluff build up with a can of spray duster with a tube nozzle and a vacuum cleaner without having to strip your laptop . So here goes.
TURN OFF YOUR LAPTOP REMOVE BATTERY AND POWER CABLE, OPEN YOUR LAPTOP SO SCREEN AND KEYBOARD ARE AT 90o, REST YOUR LAPTOP ON A SOFT CLOTH ON IT'S RIGHT SIDE SO THE COOLING HEATSINK IS UPPER MOST PUT THE VACUUM CLEANER AGAINST THE FAN INTAKE AND SPRAY DOWN THE AIR OUTLET TO DISLODGE ANY DUST, SPRAY DOWN EACH HOLE DO THIS ONCE A MONTH TO PREVENT THE OVERHEAT PROBLEM I HOPE THIS IS HELPFUL GUYS AND GALS
