FAN MOTOR MAKING NOISE SLOWING UP BEEN RUNING ABAUT 6 YEARS FIRST PROBLEM EVER

without knowing age of unit, I suggest replacing the motor. Sounds like the armature is worn the bearings and is moving inside the windings of the motor. I would do that first before moving forward with any other repairs.

try to provide more details, any strange noises? what type of compresor is it?

A noise at the end of a vent cycle, as the fan is slowing down, may also be caused by the bearings on the fan shaft starting to go bad. As they get worse, you will begin to hear the oise as the fan is runing, not just as it slows. Solution: replace fan.

cpu fan is not working properly,either is moving very fast or slow,as a result sys.will be runing hot and there is a possibility sys.will go off,clear the fan if there is any dust ,wipeout with dry cotton cloth.

It sounds like your evaporator fan motor, they last about 4-5 years. Try to see if the buzzing noise comes from the motor, usually in the freezer compartment behind a vented cover plate

The freezer is usually cooled by the compressor, the fridge is then cooled by an evaporator fan motor ($30). If this fan seizes or slows down then the fridge warms up (it sometimes starts squealing before this happens). It could be that your drain hose is clogged or frozen. Maybe the temperature adjuster go bumped.

If you think it is the evaporator fan motor:
Check to be sure you can get a replacement fan first, they last about 4 - 5 years. Can get from a parts supplier or electric motor company.
UNPLUG fridge. Located usually in top of freezer behind a vented cover plate. Remove cover, remove screws holding fan in, may have to cut wires. Replace with new motor, make sure the fan pushes air into the freezer area and doesn't spin backward drawing air from the freezer area.

is the battery ok? have it tested, sounds like a weak battery that is failing, the battery lasts about 2 years in most laptops.

I would unplug the fan and clean off the motor shaft behind the fan and vaccum the motor housing and around the motor ends.

Once you've got as much dust and grime as possible removed, use some 3-in-1 oil and LIGHTLY oil each end of the motor shaft (behind the fan and next to the motor housing) and if possible, at the other end of the motor housing.

Make sure the fan is UNPLUGGED when you do this!!! Give the fan a slow spin by hand and hold upright to allow the oil to seep down the shaft into the bearings.

I usually do this once or twice a year on my portable fans and unless the bearing isn't completely worn out, it usually helps the fan spin more easily and keeps it running very well.

Hope you find this very helpful and best regards!

The fan motor can be checked by using jumper wires. remove the wiring connector from the fan.Run the positive wire from the battery to the positive on the fan and the ground to ground. It should turn smoothly and at normal speed at 12 volts.If it is slow and noisy, the bearings making the noise. This indicates the motor is bad.

have a look at the fan on the processor if its running slow it will be making that noise so your processor is over heating and in turn making your pc run slow. replace this fan now. if your processor overheats too much it will burn out.
