Instead of cleaning it by taking it apart,
try to clean it without taking the cover out.{hassle free}

tools needed:
2 cottonbuds
1 powerful blower{hair blower will do}
1 alcohol/water{used if the dirt is hardly stick in the spindle}

instruction:
hold 1cottonbud and place it between the spindle{to make spindle not to spin while cleaning}
take the other cottonbud and poke the dirt out of the spindle one by one
then use blower to blow and clean the dirt out of the fan
dip cottonbud to the alcohol solution and use it to clean the hardly poke dirt
then blow dry your fan

How can I get my Seville desk fan to stop squeaking? When I called their toll-free number, they said their fans don't squeak. Talk about a company being in denial!! Their only suggestion was to take it to...


Remove the guard, remove the fan blade. Lay the fan on its back and drip 4 drops of 3 in 1 Oil down the spindle. Turn the spindle by hand about 6 turns and leave it overnight with the spindle upwards. The next day, run the fan with the blade off and see if the squeaking has stopped. If it has, replace the blade and guard.

If it is still squeaking, it is the bearing at the other end of the motor. That one is not quite so easy to lubricate and usually the motor would need to be fully stripped down, cleaned and lubricated.

How do I replace Gateway dx4831 fan?


The plastic snoot is probably just clipped on to the fan casing which is usually screwed to the heat sink. You could probably just remove the snoot
which will allow you to see what you need to do to remove the fan. The fan can normally be cleaned and a light grease applied to the spindle.
All you have to do is remove the fan, look underneath the fan and there should be a round label with things like the voltage, current, and make of the fan etc. Remove the label and if there is one, a little rubber bung, you will see the end of the spindle. There should be a small split washer around the spindle, it sits in a little grove on the spindle to hold it in to the fan motor. It can be removed with a small blade screwdriver. Just look for the split and carefully lift one end over the end of the spindle. Keep the washer for later. Then push the spindle out using a something like a cotton bud stem with the cotton cut off the end. It will try to go back in as it has a circular magnet inside the the fan around the outside of the spindle and is attracted to the metal part of the motor with the coils on. Clean the spindle and the hole it fits in then apply a thin grease or something like silicon oil or sewing machine oil. Push the fan spindle back in, put the split washer back and make sure it sits in the groove of the spindle by gently pushing on the end to ensure it does not slide out again. Put the rubber bung back(if there is one), clean any oil / grease from where the label sits and stick the label back on, they don't always stick once they have been removed but it can be replaced with a piece of adhesive tape.

KDS-R60xbr1 keeps shutting down


Is your Sony shutting itself off and blinking the red led 4 times? Guess what? It's the fan...

Don't waste your money buying a new one, I have the absolute easy fix:

This is a fan issue, most likely the large fan in the rear, lower left (from the back)...

Here's the fix, I promise, it's EASY........


Ok, I think I have the answer for the BIG FAN failure. I recently did a similar fix on the spindle of an xbox 360 and it is identical. Ok, this is an EXTREMELY EASY FIX...

Open the back of the tv, locate the large fan (on the lower left on the back of the set.) unscrew the screen and remove the fan.

Once the fan is removed, you will see the side with the model number and the other side is totally open.

On the open side, pull...

The fan will come off, into your hand, it is only held by magnets...

You will notice a spindle on the fan and the other side has the magnets and the hole where the spindle came from (this is the fan motor).

Clean both the spindle and the hole (motor) with a q-tip. The hole is smaller than the q-tip, but do the best you can to remove the old lubricant.

Get a bit of WD40 and lubricate the spindle and spray a touch in the hole.

Put them together, reconnect your fan, test it on start up and thank me...lol...

HOPE THIS HELPS!!!!

IT WORKS, TRUST ME...

How to replace fan motor cooling


your cooler fan has run out of lubricant, just inject a small amount of lube oil through a small opening to an oil retainer sponge just behind the bearing for maintenance.

I have cleaned the fans in the back of the tv and the light still blinks four times. I have lubricated the fans as well. What do I do now?


You said you "cleaned" the fans. Have you tried removing the large fan -- on the left side when you are standing in the back of the TV -- and actually pulling out the fan itself? One side of the fan casing has a sticker -- with the model number written on it -- and the other side is the fan itself. Carefully pull the fan out -- it's held by magnets, no screws -- then clean the spindle thoroughly with a Q-tip dipped in rubbing alcohol. Also, clean the opening on the casing itself -- the hole is too small for a Q-tip, so use a toothpick, again dipped in rubbing alcohol.

For additional cleaning, use compressed air to blow the hole. After the alcohol dries, use another Q-tip and spray a little WD40 on one of the tips. Sparingly apply the WD40 to the fan spindle. Place the fan back into the casing, screw the cover back on and try the TV again.

Good luck!

FAn problem


I really doubt it. The printers run voltages up to 30 volts, and the rpms could not be enough to cool the CPU, which could overheat and be damaged or get its life shortened. And you would be sealing your printers doom.

The best solution is that you have to buy another new Fan for your pc before it move out of hand.
The fan is faulty and the little checking you have done is some how recommended for the fan to have work better but since then you have to change it for a better one before it have anything to do with your processor Malfunction.
bye.
