how to clean your laptop cpu cooling fan

Remove the cooling fan , the following can be started on the fan and radiator maintenance operations , but before you start , we still have to prepare the necessary tools, such as brushes, rubber blower , Phillips screwdriver and a cotton swab . In order to facilitate understanding of the specific disassembly and maintenance procedures.

Step one: Remove the fan. Separated from the main radiator . The first tear the seams fan and heat sink paste , aluminum foil, and then removed the fan wind shield around the screws and remove the fan from the heat sink . At this point we can see the heat sink and fan junction accumulate a lot of dust.


Tear up the fan and fins foil , remove the screws that secure the fan

Step two: Remove the fan cover. Demolition of the fan on the roof of the wind guide cover three small screws , detach wind shield cover plate , then we can see the wind guide cover internal and fan impeller .


Will be taken out from the radiator fan , follow the arrows indicate the location of the wind guide cover removed three screws on the top cover

The third step: clean fan dust. Brush brush fan page round the edge of the dust, and then deep inside the impeller , by both sides of the blade slice clear the dust . If you encounter a dirty and difficult to remove the dirt, you can add a little water with a cotton swab to wipe . Need to remind everyone that can not get the fan directly rinse under the tap , because the fan motor is not waterproof .

Step four : Clean up fins dust. Fins with a brush brush the inside of the outlet surface accumulation of dust , and then along the direction of the air outlet fins , fins inside the brush bristles to clean deep cleaning at the same time with a rubber blower outlet from the outside to the internal body blow away loose dust, until it is completely cleaned up .
Move brush to remove the inner surface of the cooling fins accumulate dust , and then with a rubber blower for deep cleaning
Fifth step: assembling and paste the aluminum foil. Disassembled in the reverse order in accordance with the assembled fans, after the assembly , must remember the fan and aluminum fins seams paste ( can also be used instead of cloth tape ) , this can play a role in sealing aluminum foil , let the wind guide cover can all be blown to blow cool air cooling fins , but not leak from the edge of the gap .
After cleaning, the fan and the new aluminum foil pasted seams
Thus notebook fan cleaning on all completed , we need to be flexible in the dismantling , be careful, if the model is still within the warranty period , we do not suggest that you remove the entire cooling components . Of course, if you have purchased a thermal grease or laptop over the useful life of two years , in this case, you can consider replacing the new grease .

Step 1 — Motherboard

2U1C3iaJ4S61O5uI XbGcdt5nTQFf5IYH xvBi4BksiPJVRwWE

  • Lay the laptop on a flat surface, battery side up.
  •  Before proceeding, remove the battery to prevent any electrical damage to components.
  •  Remove the following screws:
    •  Five 5.8 mm Phillips screws located in the battery compartment
    •  Fifteen 7.2 mm Phillips screws securing the lower case to the upper case.
    •  Note that on some models the screw sizes and locations are mixed, i.e.: 7.2mm screws ring the case perimeter and are installed in the two “upper” locations in the battery compartment, while 5.8mm screws go in the three “lower” battery positions and the two inboard case screw locations adjacent to the RAM cover.

Step 2

  • Loosen the two captive screws on the right hand side of the hard drive cover. The screws will remain attached to the cover.
  •  Remove the hard drive by lifting it up vertically on the right hand side. There is usually a plastic pull tab to help. If not, try to gently pry it out with a flat head screwdriver
  •  Remove the one screw under the hard drive. This will help release the motherboard in later steps.

Step 3

  • Remove the screw above the RAM access cover that holds the CD drive in place. Then, slide the drive out of the case. Be careful not to pull the front off of the tray itself.
  •  Remove the 3 screws along the edge that are revealed by removing the CD drive. These hold the top bezel to the bottom frame.

Step 4

  • Flip the laptop over, keyboard side up.
  •  Carefully lift speaker grille / button panel away from the upper case by pulling up on the two corners closest to the keyboard.
  •  Remove the center cable from its connector on the button panel. Then, gently release the friction locks that secure the left and right ribbon cables by pushing them away from their connectors. The ribbon cables will slip out of their connectors.

Step 5

  • Flip the laptop over, battery side up. Remove the two screws securing the RAM shield to the lower case.
  •  Lift and remove the RAM shield up from the lower case; The screws will remain captive within the shield.
  •  Remove the black Philips screw marked with a Keyboard icon.

Step 6

  • Turn the computer over and gently lift the keyboard at the top corners, sliding it upward toward the screen. The bottom tabs will slide out from below the palm rest and the keyboard may be turned over to reveal the connection cable.
  •  Disconnect the keyboard ribbon cable (highlighted in green) from its socket on the motherboard.

Step 7

Remove the four (4) 5.8 mm Phillips screws securing the top cover to the lower case.

Step 8

  • Use a pair of tweezers to disconnect both antennas from their sockets on the wireless card. These are snap-on connectors, much like those on a 9V. battery; pull them straight up to snap them off the studs on the card.
  •  Be careful to pull on the contacts and not the wires. The crimps used to hold them to the wires are delicate.

Step 9

  • Remove the two 3.7 mm Phillips screws securing the wireless card to the motherboard.
  •  Upon removing the Phillips screws that secures the wireless card to the motherboard, the wireless card board should pop up from its top side.
  •  Grasp the wireless card and pull it straight out of its socket on the motherboard.

Step 10

  • You’ll need to remove the LCD to proceed. Start by disconnecting the marked cable from its socket and derouting the cables from their clips in the palm rest.
  •  Also pull the two WiFi antenna cables through the motherboard and deroute them from their clips.
  •  Remove the screws that hold each LCD hinge cover in place. There is 1 screw for each cover.
  •  Gently pry each cover off its hinge.

Step 11

  • Remove the Video cable by grabbing the ribbon and lifting up.
  •  Next remove the 2 screws securing the LCD hinge mounts to the bottom frame. Hold the LCD with one hand and unscrew with the other; do not leave the screen unsupported or it may bend or fall off abruptly and be damaged when the screws are removed.
  •  Lift up the LCD and its three cable bundles and set it aside.

Step 12

Use a pair of tweezers (or 3/16 nut driver) to remove the two 5mm hex screws secured to the logic board.

Step 13

  • You will need to remove the bezel under the LCD hinge to finally pull the top palm rest free.
  •  Remove the screw on the far top right hand side. Then carefully pry the bezel free.
  •  Pull the final cable connections from their sockets on the motherboard. Then gently lift the palm rest towards you starting back to front

Step 14

  • Remove the two 3.8 mm Phillips screws securing the left edge of the expansion port board to the motherboard.
  •  If present, remove the plastic “dummy card” from the expansion port.

Step 15

  • Remove the two 3.8 mm Phillips screws securing the right edge of the expansion port board to the motherboard.
  •  Lift and remove the expansion port board out of the lower case.

Step 16

  • Remove the final screw holding the motherboard in place. Then gently lift the motherboard up vertically. We need to remove a few cables.
  •  Remove the two marked cables. These will be tight. Do not pull by the wires. Carefully wiggle the connectors only. You ay find it easier to stand the case on edge and work the connectors loose using a small screwdriver or forceps, working through the RAM cover opening.
  •  Remove the final data cable near the front of the system board. The motherboard will be free. Lift up and towards the left to remove from the base.

Step 17

  • Carefully bend the left edge of the lower case outward to make sure the input ports (USB, Serial, etc.) on the motherboard are free.
  •  Lift and remove the motherboard from the lower case.

Step 18

  • Carefully set the motherboard on a non-conductive and level surface.
  •  The motherboard is static sensitive!
  •  To remove the heatsink remove the marked screws and remove the fan’s power cable. Remember to clean the CPU/heatsink and added new thermal paste
  •  Reverse these steps for reassembly.

Step 19 — Fan

  • Remove the five 5.6 mm Phillips screws securing the fan/heat sink assembly to the motherboard.
  •  Lift and remove the fan straight up from the motherboard.

Step 20

Remove the following screws securing the fan to the fan assembly:

  •  Three 3.6 mm Phillips screws located on the top side.
  •  One 3.6 mm Phillips screw located on the side of the fan assembly (highlighted in the second picture)

Step 21

  • Lift and remove the fan up out from the fan assembly.
  •  Clean the heatsink too so when you reflow, it lasts more then 2 months if you do

LAPTOP USERS: BE AWARE, can overheating laptop cause fire?

A couple lost their 25 year old son in a fire at home on June 4th. The son who had graduated with MBA from the University of Wisconsin-Madison two weeks earlier had come home for a while. He had lunch with his dad at home and decided to go back to clean up his hostel room. His father told him to wait, to meet his mother, before he went back for a few days. He decided to take a nap while waiting for his mom to come back home from work. Some time later their neighbors called 911 when they saw black smoke coming out of the house.

Unfortunately, the 25 years old died in the three year old house. It took several days of investigation to find out the cause of the fire. It was determined that the fire was caused by the laptop resting on the bed. When the laptop was on the bed cooling fan did not get the air to cool the computer and that is what caused the fire. He did not even wake up to get out of the bed because he died of breathing in carbon monoxide.

The reason I am writing this to all of you is that I have seen many of us and also our brothers& sisters sons&daughters friends&family using the laptop while in bed. Let us all decide and make it a practice not to do that. The risk is real. Let us make it a rule not to use the laptop on bed with blankets and pillows around. Please educate as many people as you can.
I would have dismissed this post as an average everyday hoax, but on searching a little further, i came across another news article “Laptop fire blamed for Vancouver death”, which claims a similar but not the exact case of the facebook post. This is the relevant quote from the article

The fire started after the computer was left on a couch, plugged in and turned on. Because of the lack of ventilation under the laptop, less than an hour later the lithium-ion battery overheated and burst into flames, sparking the fire that eventually killed the man.

HP Pavillion g6 is overheating

Installed Ubuntu 12.04 (64 bit) and the HP pavilion G6 laptop came across a small problem. The laptop is overheating badly, it becomes very hot in 5 or 10 minutes after start it. The fan is going crazy, but it doesn’t help to cool the PC. It is very strange, because it didn’t act this way when I was on Windows 7.

[Resolution] Installing the nvidia-current driver ( sudo apt-get install nvidia-current) seems to fix the problem.

Stop your laptop overheating

While all laptops will get very hot, there are several ways to help prevent overheating and crashing:

* Use a usb-powered cooling pad. This won’t keep it from getting hot but will help slow down the rate at which it gets hot, Dell Inspiron 1464 cooling fan.

*Make sure your vents are not blocked in any way. This is the only way a laptop can expell hot air and blocking them is the equivalent of cutting off your air supply. Routinely take canned air and place the straw inside each of the vent holes and give it a quick shot of air to help blow away internal dust that may be preventing the heatsink from doing its job (be careful as too much air can go past the heatsink and make the fan spin off its bearings, messing it up)

You may also wish to open up your laptop and carefully dust the inside components with canned air but doing this usually voids warranty so it’s probably best to wait until your warranty is expired. If you open your laptop off, you may also conside applying some cooling paste to the heatsink itself (there are several sites that will show you how to do this)

* Give your laptop a break. When you notice your computer getting very hot, save your progress, close down your programs and give it a break for 30-60 minutes to let it cool down some. Resoure-intensive programs like video editing, photoshop and games will make a laptop get hot faster than anything else.

* Never use your laptop on a soft surface like a bed, blanket, etc. These can easily block the vents and trap heat inside without you even realizing it. Take the same precaution for your power adapter. I had a power adapter fry on me because I inadvertantly had it covered by a blanket.

*When not using your laptop (such as when you’re sleeping), power it off and allow it several hours to cool internal components off, Hp Pavilion G7-2234ca fan.

If you want to keep your laptop, take these precautions and do NOT let your laptop overheat to the point where it shuts itself down. This actually does harm to your computer. With my last laptop I was naive to the overheating problem and it messed up my hard drive to where windows wouldn’t even start right and would crash randomly. You need to ask yourself what’s worse: having to stop working for a bit or having your computer permanently damaged by overheating?

Tips to keep Your Laptop from Overheating

Don’t use your laptop on soft surfaces such as a sofa, carpeting or pillow! Any vents located on the bottom of your laptop will be blocked and airflow will be reduced causing it to overheat. Use a lap desk, tray table or even a wooden cutting board to provide a solid, flat surface to allow proper airflow Hp Pavilion Dv6-6000 cooling fan.

Use a can of compressed air on your fan once in a month so that any dust or unwanted particles get cleared for the smooth functioning of the fan. Using a vacuum may cause ESD and damage the components to your laptop.

If you’ve had your laptop for a while, consider replacing its battery.
Be sure to clean out your laptop thoroughly once in while to avoid dust particles entering in places they are not needed.

Simply add the spare wire grill tray from your toaster oven or even your regular oven. Balance is perfect and air circulation is just as perfect.

SMCfancontrol which allows you to set up different fan speeds depending on what the mac is doing and I keep the temp around 40 degrees, use it to keep your laptop cool.

Cool down an overheated laptop

A hot computer is a bad computer. Excess heat can cause malfunctions and crashes, and permanently damage your hardware. And although laptops generally put out less heat than desktops (energy efficiency is a higher design priority), they have their own unique problems. They’re rarely as well ventilated as a desktop, and much more difficult to clean.

Keeping a laptop cool is all about ventilation. If the hot air can’t escape, you’re going to have a problem.

Whenever your laptop is on, make sure that nothing blocks the vents (which are probably on the sides). Don’t put the PC on a pillow or a soft mattress, where it’s likely to sink in and get blocked.

And never, ever put your laptop in a bag unless it’s off, hybernated, or in sleep mode.

You’ll rarely find vents at the bottom of a laptop, yet heat tends to accumulate there. If the bottom is hot to the touch, consider buying a laptop cooler–a pad that goes under the laptop and whisks away the heat. Many of them have fans. Prices range from about $8 to $40.

I’m not going to recommend a particular model because I don’t use one. At least for my laptop, an empty but sturdy cardboard box is sufficient.

If you let dust accumulate in a PC, you’re bound to have problems. And you’ll have to fix those problems with a good cleaning.

Marco Chiappetta described the cleaning process in You’re a dirty, dirty, dusty PC. But he used a desktop, and desktop PCs are designed for easy user maintenance.

Laptops are trickier. You can try using a can of compressed air (I bought one recently for $4) to blow the dust away from the vents. But that’s a very limited solution. The dust may get away from the vent, but it’s still inside the PC.

Try this: Shut down the laptop and turn it over. Examine the bottom. You’ll likely find panels that can be removed with a small screwdriver. Open them up and see what you get access to. If you see dust, clean it away with compressed air.

Unfortunately, the real dust problem may be in places that require a more complicated dismantling. If you feel comfortable taking apart a laptop, go ahead. Otherwise, you may want to take it to a professional.

Acer’s Aspire V5

The touch-pad is definitely skittish, and using the adjustment to reduce sensitivity does not improve the situation. One must be careful to hold one’s hands well above the keyboard to avoid accidental “thumbing” of the touch-pad. Or, disable the touch-pad and use an external mouse; disabling is easy with a button for that purpose on the keyboard.

Yes, the Acer V5 is elegantly “super thin”. Put it on a catwalk! But this whole trend toward “super-thinness” in laptops serves no purpose and actually compromises functional quality. Because of the Acer V5 “super thin” design, a couple of sockets (the Ethernet being one of them) won’t fit on the side of the body; so Acer provides the buyer with a Y connector cable as a separate attachment/adapter–how bogus and ridiculous is that!? It is a step backward, not forward.

Windows 8 operating system: the user interface is the dog of dogs! How incredibly confusing and not user friendly! But, don’t give up hope. Download and install Classic Shell, beautifully designed free software that gives W8 the look and feel of Windows 7, while still allowing the option of using W8 interface when you want that.
