Loud noises coming from power supply fan?

I can run my computer for hours, then a loud noise comes from the fan by the power supply( not 100% sure.) Sometimes it happens within an hour, other times it has run for 12 hours before it happens. The only way to get it to stop is to shut down my computer and the turn it back on. Once in a great while it stops on it's own. It just happens whenever it feels like it. This has been happening for about 4 months.

It might be the fan of your cpu has dust.and making it the fan hard to spindle.if you can dismantle your cpu fan or the fan in your power supply.just clean it with the paint brush.or do it with vaccum cleaner.if you have air compressor the would be better.just blow out the dust.then if you can do it also just putting oil or grease inside the fan at the core.the one that has magnet.it will smoothen the spindling.ok good luck

Humming noise


Possibly a bad cable or bad ground or bad outlet?. Easy solution, try a different outlet and see if the hum still exists. Also, make sure your speaker cables are NOT run parallel along with, or close to any power cables, Speaker wires can and will pick up AC "Humm" noise.

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.

Dell 3300mp Projector Loud Noise


Judging by the mains hum noise and now shaking it sounds as if a motorized component has broken.
Humming could have been the initial jam, then shaking the damaged part attempting to rotate.
Maybe check your cooling fan blades?

Loud Buzzing Noise from Behind Freezer


Sounds like the freezer fan blade is hitting on a build up of ice or frost. You may have a defrost issue, or it may be a one time thing, like the door was open for a long time (object holding door partially open) or also check the ice dispenser duct door to make sure it is closing. Sometimes a chunk of ice hangs up in the ice shoot, allowing moist air to enter freezer, resulting in the extra frost / ice near the freezer fan. You might also check the door gaskets, especially the bottom side where sugary liquid spills might cause a gasket to tear. #2: Long run times: If cooling is good, don't worry. Older refrig's often ran less time, but used much more electricity than the newer refrig's, even though new one run longer. (Like having a 40 watt light bulb on for 20 hours a day uses less electricity than having a 100 watt bulb on for 10 hours a day)

The fan is makeing a load noise


Get a can of compressed air and make sure the fan is clean of gunk/dust. If its the fan built into the power supply, and have been noticing the computer not respoinding as good as used to, the you might need a new power supply. http://www.factorydirect.ca/catalog/category_list.php?cat=0700

If the loud noise is coming from a seperate fan, again make sure if it is clean. If it still makes noises, then you might need a new fan.

Loud noise


Typical problem in most computers, the fan is experiencing a "burn out." This means there is either something caught in the fan causing it to create noise, or the motor is going bad. there are two fixes for this problem.
1) open you computer's case according to its manual and remove the system cooling fan and give it a thorough cleaning.
2) you may need to replace the cooling fan with its recommended replacement model.

Hope this helps!

Cooling fan


Yes. It can be replaced. Try to check which fan is making that sound. Do you have a laptop or a PC? On a PC, there are 3 standard fans inside it. one for the CPU, one for the power supply and one for the computer casing fan as well. It depends on which of those fans it's coming from. On a laptop, some laptops' fans actually makes a loud noise which is common but there is a way that it could be lessened but it might slow down your pc and it might overheat it as well. The loud noise on the fans of a laptop actually indicates that it's trying to cool down the system. If it doesn't stop the loud noise, it could indicate a problem switching the fans back to normal and would just continue to spin fast. Try to contact your PC tech for further diagnostics on the laptops fan to indicate if the problem is with the fan or the mainboard as well.
