Mid December I started having some intense overheating problems with my DV7-3180us Notebook running on Windows 7 64-bit.
The computer often black-screen crashed as a result of the heatsink fan failing and my motherboard being damaged in the process. So I sent it in to HP Diagnostic and Repair and in 2 weeks I got it back and it was working great.
Now my problem, 2 days after my 90 day waranty expired, the system started overheating again and crashing during gaming/streaming. So I used HW Monitor to check the temperatures.
Idle: 50C average CPU amongst all cores. 60C for the GeForce GT 230M video card.
Gaming: 88C average CPU after 10 minutes. 92C video card after 10 minutes.
I quit the game as these temperatures started to scare me. It's almost as if the heatsink fan stopped working entirely. I place my hand under the exit vents on the top left side of the computer and I feel no airflow whatsoever. Now since I got this back, I have air-can cleaned out the vents every week and avoided very intense gaming, but the fan still failed. What gets me frustrated is that I am going to have to spend more money repairing a fan that isn't even half a year old. I don't know what happened to the fan...HP may have not applied thermal paste or just gave my computer a defective fan. Either way I am going end up paying a great deal. This is my last HP laptop, not just because of bad repair job, but poor designs and an overwhelming horde of unhappy customers of the DV7.
Just to give some more info:
I updated my drivers/BIOS from the HP website.
I have not recently bumped or overclocked my laptop to cause the fan to be dislodged (Infact it is just stationary since I recieved it back.
I have not opened it up, as the warrenty from the previous fix would have been void.
It is resting on a metal-mesh surface for airflow and the back is proped up half an inch.
Room temperature is 68F.

Have you used external fans. I use external fans Rite Aid has a real cheep fold up pocket fan for $10.00 just plug it into usb port and set your computer on it. Thats what I use with my HP DV7-6135dx . Oh by the way HP warranty is for one year not 90 days comes any computer sold in USA new. So you know. They also sell more expensive laptop cooler pads from $20.00 to $30.00 at Staples and Office Depot. When I use my fan the laptop fans hardly ever kick on. They run but at very low speed. Ounce you get your fans fix I recomend using external fans. This will help keeping the fans from running high all the time.

Yes I have tried external fans. The change isn't noticeable as the GPU sitll heats to 90C+ temps in a few minutes no matter the orientation under my comp. The heatsink vents are just not giving out any pressure, so all the heat generated at the top left where the GPU and CPU are is overheating the systemboard leading to crashes. The heat produced by that single location on the computer is enough to burn my fingers numb.
Back in early January when I sent it in to HP Diagnostic, it was sent back with a temporary warranty for 90 days, so if it breaks again in that 90 days I can send it back free of charge. That warranty had just ran out when the fan started failing.
But when I get it back from the local shop, I will definately pull out the external fan again.
Also on a side note, I want to monitor my computer functions closely from now on. I find both HW Monitor and Speedfan work great, but neither can find the sensor for my fan-speeds. Anyone know of a better program that works for HP laptops?

I have the exact same notebook. It only seriously overheats when I play graphics intensive action games, e.g.. first person shooters, otherwise it runs pretty cool. When the system starts to get really hot I notice that the cooling fan starts cycling on and off, which doesn't make any sense because that only allows the CPU/GPU to heat up to dangerous levels even faster. I have updated the BIOS to the must current version and there has been no change. I have the fan set to 'always on'. If the fan is directly controlled by the BIOS then I'd say HP needs to release a new version ASAP that corrects this condition.

Here is what happened with my HP DV7 7047 cl. It has a manufacturers defect in it, that I fixed myself. I bought mine at SAMS CLUB in the summer of 2012. It is a i7 beats edition DV7 notebook, I'm guessing the same thing is happening with HP's line of DV6 and DV7 laptops. Mine has a nvidia GPU in it, but they also come with ati radeon GPU's. It isn't surprising they are taking them off the market right now.
If your laptop has 2 vents, and the one in the back is not blowing air through it then your laptop possibly has the same problem mine had, and you need to take it to replace the inner fan piece which was designed for only one vent. The way it works is both of these vents are made out of aluminum and are separately connected to the CPU and GPU. The one to the side is your GPU one. The aluminum vent in the back cools your CPU. If your CPU isn't getting any ventilation then your laptop wont last long and could possibly start a fire. Here is how I fixed mine by myself. And how you can fix yours too.
Before taking it apart call HP Support and ask them if you can open it up to "clean it". They will give you permission so it doesn't void the HP warranty.
My laptop would reach between 70c, 80c, 90c, even 100c and would get extremely hot, but wouldn't overheat. And I was concerned because my laptop is only 3 months old. It would get very hot. So I decided to take it apart and see what was going on inside. I followed the instructions on HP's website, they have online guides and manuals for taking your laptop apart and putting it back together. If you need instructions on finding your manual for your laptop then email me at [Personal Information Removed]. Doing this fixed my laptop entirely. It never gets hot now, it runs faster and can play games at their maximum settings. The CPU will stay only at 60c, 65c at its tops. It's like magic.
Here is how you can surgically correct your faulty laptop fan. You're going to make an opening in the fan, cutting a bit of plastic off, so that the other vent to your CPU can get ventilation, if worst comes to worst, you can jot down the name of the fan on the sticker and go to HP's website and order a new piece to replace it for like 50 bucks.
What you need is...
A small screwdriver
A tiny screwdriver
And (optional) some thermal compound to replace your cooked old compound. Mine was like chalk, I replaced it and it helped cool down my laptop by like 10c. You can get thermal compound at Radio Shack, and the silver stuff is the best.
First open it up carefully, take your time, and take out the motherboard. Its the big chip with the fan connected to it and the aluminum vents.
Next, If you're planning on replacing your thermal compound, then unscrew the bolts on the heat sinks and take the big metal pieces off the chip, place your motherboard chip to the side. Now take the piece with your heat sinks, fan and vents connected to it, and turn it around.
Next unscrew the 4 or 5 tiny bolts behind the fan. So you can take the inner fan piece out. Notice its shape, does it have an opening for your other vent? If not, then make one. Cut an opening in the plastic, the size of the other vent. I used a knife carefully angled to cut the plastic off. Once I cut it, I just bent it off the bottom to take it off. Place the fan back into its frame and screw in the tiny bolts.
Now replace your thermal compound. You can use a Q tip with the cotton off of it, to scrape off the old gunk - then clean it with a slightly wet Q tip. You can use a little rubbing alcohol but you shouldn't need much. Next put a drop of the new compound on the heat sinks and the chip. Using some plastic wrap on your finger even it carefully on top of the little silver parts where the old stuff was.
Now you're good to put it all back together. Gently place the heat sinks on the chip and don't move them while you screw the heat sinks back into the chip.
Carefully put the laptop back together and you're done.
Here's a picture of my fan, and how I fixed mine. I didn't bother to take the piece out when I took the picture cause those tiny bolts are a PAIN to take out with a knife when you don't have a tiny screwdriver.
Here is a new picture of my updated Fan mod
