Fan makes noise on my Dell Inspiron One 19


Usually there is a fan on the CPU heatsink and a fan in the power supply.
Open the case and turn on the computer and use a small timber stick and poke it into the CPU fan to stop it spinning and if the noise stops then this fan needs replacing.
If it is OK the the fan in the power supply is faulty. I recommend you replace the power supply because there are dangerous voltages inside this power supply.

Dell optiplex GX280 PC when power on system no noise with fan after one hour making loud noise . I changed the CPU fan , also same noise, and applied heat sink paste to CPU and heat sink same noise....


There probably is another fan, located inside the power-supply, that is making all the noise.

Borrow a stethoscope from a nurse or doctor, and listen to the noise, to pinpoint "where" on the computer that is the origin of the noise.

My computer started making a loud noise that will not stop. I am not sure if it is the fan or hard drive. The computer seems to be working fine. Any idea what could be making the noise?


In order to confirm the problem.. first of all turn off the pc and unplug the power cable from the back of the pc.... get a Philips head screw driver and open the chasis.... plug in the power cable and see where are you getting the noise from .... there are three fans namely one on the processor, the other a cooling fan and the last would be inside the power supply.. if its inside the power supply nothing can be done ... if its the cooling fan noise .... try to clean the vents or the cooling fan with the help of the dry cloth and if its the processor fan then its a serious issue ....

Sounds like the fan is wearing out, as it heats up the fan needs to spin faster and if the bearings are wearing out it will start getting louder and it will also get hotter because the fan cannot keep up the heat being produced. You can replace the fan, most computer shops will carry replacements, also get a can of compressed air and give the inside of the computer a good cleaning. This will help keep things cooler as well. Also make sure that the air vents on the outside of the case are clear as well.

One of my fans has started making noise, how much time do i have to replace it? Am I right in thinking that it making noise that it needs to be replaced?


fan noises are usually caused by worn out fans. but can be also caused by IDE/power cables hitting the fan blades. you will have to open up the computer to see where the noise comes from.

if it is a faulty fan, replace it sooner than later as it will get louder and louder. then stop making noise all together when the fan fails.

This could be caused by the harddrive. There might be a bad bearing or something. Please backup all your data. You will probably have to replace the hard drive sooner or later.

Cpu fan noise problem


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.
