xxx fan ,makes too much noise

Usually, this occurs when the fan has accumulated dust. You should clean the area with a blower where is the cpu fan. If the noise persists, you must have replace your CPU fan latpop.

A high pitched noise from the fan unit, means a bearing issue from the motor. You must replace the fan motor to get rid of the noise.

Refrigerators are not the most complicated appliance in the house, but it still takes a lot of parts working together perfectly to keep your food cold. If one of those parts breaks down, or begins to, you may start to hear new noises from your refrigerator. Fridges make some noise during regular operation, but if it suddenly gets louder or makes a different noise, it is a good sign that something is wrong.

Freezer Fan
Freezers can be located on either side of the refrigerator, or may be at the top or the bottom of the unit. If you hear a noise coming from the area in which the freezer is located, you should open the freezer and see if the noise gets louder. Any squealing sounds coming from this area indicate a broken freezer fan. These units are not designed to be repaired, and eventually one making a loud noise will break and need replacement.

Condenser Fan
All motors typically require a fan in order to maintain a safe operating temperature. Like the fan in the freezer, the fan that runs on the condenser can also break down and create a similar squealing noise. The location of the fan noise is what differentiates the freezer and condenser fan problems. If you hear a fan noise coming from the lower part of the fridge at the rear, it is likely the condenser fan causing the problem.

Action to do
Open the freezer to see if the noise gets louder. If the noise becomes louder with the freezer open, the noise is likely caused by the evaporator fan. If the evaporator fan is the culprit, replace it to get rid of the noise.

Pull the refrigerator away from the wall, and check the condenser fan at the back of the fridge. A metal panel may cover the fan, which can be unscrewed. Listen to see if the fan is the source of the noise. If it is, the fan may need to be cleaned or replaced.

Good day ! : )

Is it a clicking noise? Hissing noise? or maybe a grinding noise? A pc can cause many different noises. A clicking noise generally means the hard drive is failing. You'd want to back up your data immediately and get a new drive. Hissing can be a bad fan or CD/DVD drive that needs to be replaced. Grinding noises can also be caused by fan bearings going out. You would need to find out which fan it is, and replace that fan.

If it is a clicking noise, then that means your hard drive is probably starting to go. If it's a humming noise, then it's the system fan that keeps the computer cool. Try cleaning the fan and if that doesn't work, purchase a new one and replace. They are fairly cheap and easy to replace. If the fan stops working, it can cause the computer to heat up and may cause components such as the processor and hard drive to fail.

Hello
Yeah this noise should be the fan's noise, if the fan goes dried it need lubrication, and if the fan gone bad needs replacement to overcome the noise.
Good Luck

sometimes dust accumalates on fins of fans and causes rotation to deform and gets fan off balance causing noise .Also heat from lamp causes deformaties on fan and causes fan bearing to make noise.These fans can be replaced fairly easily

The buzzing noise would normally be either a fan or color wheel that is failing.

You should check and make sure the inside of your computer isn't dusty. Dust will wreak havok on fans and shorten their life. Plus it likes to build up between the fan and heatsink which will overheat your processor. Take the fan off and spin it with your fingers. I like to open the little sticker on the bottom and put some 3 in 1 oil to lubricate it. A smooth spinning fan is a happy computer. It also reduces noise that a dirty fan makes. Hope this helps you.
