cleaning the fan of a dell laptop
What is the way to reduce laptop fan noise? Cleaning the computer’s vents, adjusting the energy use settings, or purchasing a laptop cooler are just a few ways to quiet a laptop fan. Excessive fan noise indicates the computer is overheated. Why does my laptop get so hot? How do you reset a laptop? How do you connect a laptop to a TV? The purpose of a laptop fan is to keep the computer’s circuitry cool. Typically, it should only run for a few seconds at a time. If the fan runs for longer than 20 seconds or makes an unusual noise, that means the computer is overheated and could indicate an underlying problem.The solution may be as simple as adjusting the computer’s energy settings. Owners should consult their owner’s manuals for how to do this, as it varies among operating systems. Most computers have an energy saver mode that dims the screen or decreases “awake” time, thereby reducing the power and heat the computer generates.Simply closing tabs or reducing the use of programs that place high demands on the computer, like gaming or video editing software, can keep the computer from overheating.
Another option is to buy a laptop cooler, a device that is placed underneath the laptop and plugs into the USB port.Brushing dust and lint away from the fan vents will increase airflow, quieting the fan. Computer users familiar with electronics can open the laptop and clean the fan and circuitry with a can of compressed air. Owners should keep in mind, however, that this type of repair may void the computer’s warranty. Learn more about Computers & Hardware How can you get a totally free laptop?

air duct cleaning with truck mount Here's how it works: Anybody can ask a question The best answers are voted up and rise to the top To get rid of dust that had gathered near the fan, I put a vacuum cleaner to the air intake (with the computer turned off). This removed the dust. It also caused the fan to rotate at a fairly high speed. Quite faster than normal speed, judging from the sound. Do I risk destroying stuff by doing this? You could damage the fan from spinning it that way. You could also damage many components in the PC using a vacuum cleaner - it generates a large amount of static electricity! You should NEVER use a vacuum on electronic equipment! The proper thing to do would be to open the machine out and blow the dust free with non-static compressed air.
(It's best to hold fans still rather than letting them spin freely for the same reason having the vacuum spin them up is bad, but very few people bother to do this because with quick bursts of air the odds are very slight.) I have been told that each motor of the PC's fans relies on bushings, that are built to tolerate a certain RPM. Exceeding that RPM, such as when large volumes flow, can reduce the life of the fans. In addition, off-center suction can place a tangential torque on the axle of the fan. So you do risk this kind of damage as well. I have done it to many many machines and have not reduced the useful life of expensive fans. You can definitely destroy a cheap fan very easily. For desktops, fans are easily replaced. For laptops...not so much. Sign up or log in Sign up using Google Sign up using Email and Password Post as a guest By posting your answer, you agree to the privacy policy and terms of service.

BTW, I'm working on this notebook because I was asked to bypass the power connector as a favor. got five kids in the house and I burned my finger on the metal part of the 100BaseT port after I got it charging again, so I'm afraid to return it for The problem I was originally asked to fix should have tipped me off to the overheating issues this notebook would suffer. The pin had broken out of the center of the power connector on the motherboard, which meant the batteryMy fix (really a kludge) was to solder a new wire directly to the connector and bring it out the I/O port blank on the back of the notebook.
The coax power cable was HUGE. Turned out to be rated for 2.0 amps. secure the keyboard in the laptop, and it's not even necessary to disconnect the ribbon connector from the motherboard to access the fans. laptop uses two fans, a large exhaust fan that pulls cooling air through the body of the notebook, and a smaller CPU fan on top of the large heatsink. The large fan to the right draws cooling air in the bottom of the laptop, the smaller fan in the center is directly cooling the CPU. overheating is pretty much limited to making sure the laptop fans operate and aren't completely burried in lint. This is a pretty robust cooling system and likely to keep most laptops from shutting down from thermal overload protection, but they stuck a P4 2.8 Ghz CPU in this puppy! When I went out on the web and read some reviews of how this laptop performed when new, I saw comments like "Keyboard gets too hot to type" and "Frequent shutdowns
Sony made a Vaio with the same CPU, HP made an Pavilion and Dell an Inspiron. I've seen similar overheating and battery life complaints for them as well. As you can see to the left, there was a build-up of dust on the CPU fan which I blew out with compressed air, but not enough to cause any thermal shutdownThe reason I burned my finger on this boat anchor is it just runs too hot as a design flaw. OK, I didn't get a blister, but I'm afraid to put this laptop with a kludged power connector in a family home. know how they could have forced more air through this thing than with the big intake fan they are already using, so troubleshooting includes making sure you have unobstructed airflow to the BOTTOM of the laptop for the fanIf you run the thing on a bed, or on your lap with the fan grille blocked by your leg, it's going to cook for sure!
