Computers fan runs alot

by Carolyn123 / July 17, 2010 10:10 PM PDT

Hi. I have a HP Pavillion Elite and this problem started occuring after we had a power failure the other night. When I start the computer, after about 5 minutes the fan starts and will not shut off. I tried putting it into the sleep mode and then turn back on and that seems to stop the fan from running. What could be the problem. The computer is only 7 months old.

Well inside the warranty so make it their problem. Yes you could system restore to the day before the power loss but in warranty means you have options.

Reasons for CPU fans running constantly!

In reply to: Fan problems

Computers allow us to connect with people from around the world, and successfully complete school and business work. Unfortunately, technical issues can arise after prolonged use of a computer or due to manufacturer issues. A computer fan that runs all the time can be from your personal habits when using your computer. Fortunately inexpensive steps can be taken to resolve the matter.

1. ventilation
If you are using a laptop computer in your lap or on a cloth for an extended period of time, your computer may be overheating, causing the fan consistently run. Since the computer has little insulation between the surface and the motherboard, the fan stays on. Purchase a cooling pad for the laptop. It can be found at your local office supply store. If you don't want to buy a cooling pad, you can periodically lift your laptop up and sit it on a desk, countertop or another flat surface.

If your desktop is overheating, it could be because it is in a small area with with little ventilation. Ensure your desktop is in an area that allows air to circulate.

2. Dust
You computer fan may have accumulated a lot of dust, which causes the fan to run continuously. Purchase compressed air and periodically spray the computer fan to loosen up any dust that may have accumulated. Most computer fans are exposed, so accessing the fan should not be a challenge.

3. Technical issues
In some cases, your computer may have either a defective fan or thermostat. Computer providers, such as Dell, allow you to purchase a new fan and replace it yourself. For thermostat issues, you may have to contact a computer repair professional for assistance.

4. Computer is overworked
Depending on the age of your computer multiple programs that are running can cause it to overheat. Watching a lot of DVDs, playing video games, and listening to music on your computer also can cause overheating. Considering closing some of your programs and rebooting your computer.

5. Viruses or spyware
Spyware can continuously run on your computer, causing the fan to overheat. Spyware is software that may have installed on your computer without your knowledge. Perform a virus and spyware scan on your computer. offers free or paid software for spyware and virus scanning and removal.

Good luck!

Generic Responce?

The respondent sound like he is reading from his script in Bangalore, or he is hoping to get you to visit his website.
There are many reasons for the fan to run irregularly or constantly. Flash your BIOS for starters and maybe look at driver problems. First of course do some time traveling and restore your machine to an earlier time, like someone else suggested. Being as you have an HP, you can go to HP website and finsd all the drivers and bios for your machine. Use the Autodetect to get the exact model of your computer. Good Luck.

I had this problem for months now and just lived with the noise of a Jet-plane from my CPU. Some days ago I decided to upgrade and install a new RAM card, so I opened her up and WOW ! The amount of dust was awesome.
Main place to clean is right below the Processor Fan. Some of us like to remove it and clean outside, but I did just fine with a small vacuum-cleaner and a stiff brush.
The difference is awesome and my machine runs cooler. WIN WIN all ways.
Now I will do this every 4 months or so !!
good luck !

Removing dust
by geognerd / July 24, 2010 3:01 PM PDT
In reply to: DUST AND GRIME...

I second the suggestion to open the case and look for dust buildup. However, I wouldn't recommend the use of a vacuum cleaner. Static electricity can develop at the end of the nozzle and could discharge onto the electronics in the case, ruining your computer. A safer choice would be to use a can of compressed air and use brief puffs to loosen the dust, then blow away.
