How to clean cooling fan acer extensa 4630


Why do you want to clean the fan ? What is the problem with your laptop ?
First read this and follow the instructions
http://acer.custhelp.com/app/answers/detail/a_id/418/
Second, try acer support, the chat facility is good, but you will your laptop serial number (22 digits usually)
Finally if you are determined to clean the actual fan thoroughly you will need disassemble your laptop. Instructions for carrying out this difficult process can be found in the service manual which you can find here:
http://www.manualslib.com/products/Acer-Extensa-4630-2178214.html
This video
http://www.laptopinventory.com/LaptopInventory.php/Acer/Extensa/4630/Fan
shows the general idea (the guy demonstrating is very practiced, and the video is speeded up in places, and it takes him 15 minutes).
You can try blowing compressed air (from a can) through the fan by applying it to the vents, but unless you can prevent the fan from turning, this can generate damaging voltages (fan acts as a generator). You can get away with this if you stop the fan from turning, or least only allow it to turn slowly.

I dropped my Sony PCG-3E2L and now the fan is not running. Lap top shouts off after a few min


If the fan is not running you should use the computer because you could cause it to overheat and become very damaged. Right now it is possible that JUST the fan is broken, which would be a simple fix. The reason the computer is shutting off after a few minutes is because it's trying to save itself from melting. You need to remove the fan, find the manufacturer and model number on the fan and order a replcement and install it before you attempt to use the computer any further.

I hope this helps! If not, please comment back and let us know!

Bad power switch


Okay but you need to be very careful. Open ther server up and short the power switch wires. Trace the power wire to the motherboard, take it out, and short the two pins on the motherboard with a piece of metal and as soon as it's on remove the metal. A more permanent way is to replace the power switch obviously.

Targus Chill Mat Fan On Fritz


The fan rotor is stuck due to accumulation of dust. Take out the fan and clean it. Put a few drops of alcohol or lacquer thinner on the rotor/bushing assembly while manually turning its blades to loosen the hardened dirt until the fan freely spins like the good one. If it does not work, replace the defective fan if spare is available.

Compaq Presario SR1365CL (4) yrs old, fan making annoying noice


Often you can blow the dust out of the fans and it will help. In your case the bearings have most likely dried up on a fan. First blow the dust out of all the fans. To find the offending fan you will have to block the blades with something. Once the fan is found you can either replace it with a fan of the same size or re-oil the bearings. To re-oil, carefully peal away the label on the fan. There might be a plastic plug over the bearing, carefully remove it. Drop a few drops of 4-in-1 oil or sewing machine oil into the bearing. Stick the label back on and put the fan back into the system. It should be much quieter now.

Greetings,
I believe that the 'silver pad' you are talking about is likely a thermal pad which creates intimate thermal contact in the same manner as a thermal compound. As long as the pad has not deteriorated then you can reuse it. If that helped please rate me well.

Desamble a brushless fan...


Remove the label from the center of the fan.
Look inside the hole. Some have a rubber bung in the hole.
The fan is usually retained in the housing by a nylon washer with a split in it.
Get something like a really thin blade/needle and you can ease it off the fan spindle without breaking it. It sits in a groove on the fan spindle.

Fan Noise on Dell Dimension 8100


All computer fans have a general design.  The name in front of "fan" really refers to the designation.  You'll see case fan, processor fan, CPU fan, cooling fan, etc.  In the case of CPU/Processor fan, some are sold with heatsinks (the metal block sitting on top of your CPU).

The first thing you want to do is make sure the fan is clean.  Chances are dust buildup is causing the excess noise.

If that's not the case and you're looking to replace the fan, then you first need to find out the size of the fan. General sizes(diameter X width in mm) are listed on this page:

http://www.svc.com/case-fans.html

Generally, you're looking for something that will match the size of what you're replacing & push enough air at a reasonable noise level to cool the heatsink/CPU.  You want to stay in the area of 30dBA max for noise.  You also want to see if it has a 3-pin or 4-pin connection.

For example, if you have an 80mm fan, I would suggest something like this:

http://www.svc.com/saf-b82-19.html

It's pretty quiet with good airflow.  Also, it has a 3-pin connection, but includes an adapter for a 4-pin connection.
