My computer is a HP Pavilion dv4-1123us Entertainment Notebook Pc. Whenever I use any program that increases the computer cpu usage to around 40%, the fan will start running constantly from a little sound to very loud noise. I thought that his was caused by some program so I bought recovery disks to recover the computer back to original factory condition. Although I tried, it didn't not solve the problem at all. I also though it is because of the Bios so I updated that too. I have not experienced this at all when I bought it, but I experienced after several months. Is it because of the Intel Chipset when I forgot to install it and when the laptop got very hot? Is it because of the Bios because I updated it wrong? Please help me solve it.

Your fan is coming on when your CPU hits around 40%, huh?
Did you know CPUs get very, very hot? And when they are being used, they start getting hotter.
So when your CPU usage goes up, your fan starts working to cool it down.
My desktop's CPU fan runs constantly, and it has better ventilation than your ntoebook.

wow, so many post. Well, if "whosoever reads this"'s fan on the laptop is constantly spinning high there are a few things to consider.
1. Your cpu's thermo grease could be getting worn out.
2. Your fan is not that great and I would highly suggest either bringing it to HP's attention provided your laptop is still under warranty.
3. You are running (let's say) high performance games (not apps because I do alot of programming in vs 2008/2010 and never get to 70c), and need to lower your cpu frequency to lower your heat generation and lower your gpu because your gpu and cpu do use the same heat sink.
4. Even if you are on a flat surface (not on cloth or anything that can absorb the heat but rather push is away like a desktop, varnished wood, etc...), you have a build up of dust blocking the vents which will cause your fan to work harder. Clean it out.
And if all these things are heeded, next get you a laptop mat with a fan or two to help keep the underneath cool. Remember,
ram does generate heat too and if your ram is close to your cpu or gpu, they will feel the affect.

I have the same problem. I just worked with an HP Tech and he instructed me to get out my hair blow dryer and the the dryer on low and blow into the fan area. ???????????????? It felt wrong...and the problem is not fixed

I had own 3 HP notebooks:
HP has poor thermal solution design. It makes all my HP notebook have the same issue. Fan constant running even you just run windows without any application. With the aging of your machine, the noise becoming louder until you bought new one.
had DV5000, which work fine when it was new. However after two years use, it's noise become unacceptable level, I had to change to Dell Laptop. (Dell laptop is much cool and quiet than HP's)
I have HP2530. It use cheap fan, when I bought it, the first thing I did is change setting in bios to make the fan only spin when it necessary, this will prolong the fan life. Also reduce the noisy time.
Recently I bought G7 1150, about half price of my first HP laptop. The fan is cheap than zv5000 but better than EliteBook 2530p. If have more buck, I will prefer Dell's studio of core2. They really quite when you just writing something with word.
A better substitute of HP 1150us, will be Dell Inspiron 15R-2nd Gen. They are similar price ($450 to $500) and config. But dell's has more recent features than HP:
1. 15" screen instead of 17"
2. Better feeling of keyboard
3. 2nd generation of i3 2310 vs 1st generation of i3-370M (performance are same with bench mark)
4. widi support
5. running less noise and heat when runing light load
6. usb 3.0 vs usb2.0
7. Bluetooth vs none on HP
8. Weight are similar. Dell 6.3/HP 6.1 pond
