- HP Pavilion DV7-2070eg fan noise & CPU overheating uses direct physical contact to cool the AC unit
- HP Pavilion Dv 7, Heat Problems claims it is a driver problem that causes the CPU to overwork. This can be easily verified using the Task Manager. In this article the Sound driver is said to be the cause.
HP Pavilion dv7 notebook running way too hot recommends getting from Cool Master a 3-fan cooler that can be targeted on the hot spots, as well as another much more drastic solution:

Have you ever cleaned out the fan or air duct? Most times this gets so filled with dust that air cannot pass through it very well.
I would suggest then also seeing if there is an update for your bios, this might give you more features or controls
then I would consider updating drivers for your graphics card and possibly doing things like disabling aero, etc...
I have a compaq laptop that had Vista on it, the fan was always on full speed, I installed linux on it and something seemed odd and I couldnt figure out what it was until I heard the fan turn on for a few minutes and then turn off... It ran WAY cooler under linux where it wasnt constantly taxing the GPU and CPU.
If this still doesnt seem to do the trick for you, get one of them laptop fan pads that has fans built into the bottom of it that you can set your laptop on. Although bulky and not idea, it will help keep your laptop usable.
how can i control the fan speed in windows?

is there a way of adjusting fan speed w software? I tried SpeedFan but no luck
Please check your fan isn't full of dust as this is a huge problem for laptops, also try this:
Select "Control Panel" from the Start menu.
Click “Hardware and Sound,” and then “Power Options.” A new window opens.
Click “Change Plan Settings,” and then “Change Advanced Power Settings.” The “Power Options” dialog box opens.
Select the “Advanced Settings” tab.
Click the plus symbol associated with “Processor Power Management” to open an options submenu.
Select “System Cooling Policy” from the submenu.
Click the down arrow under “System Cooling Policy” to reveal a drop-down menu.
Select “Active” from the drop-down menu to increase the speed of your CPU’s cooling fan.
Click “Apply” and then “OK.”
Hope it helps.
try msi afterburner, you can set a custom fan speed curve but im not sure itll work with all laptop gpu fans
