Fan makes loud noise after computer warms up. I do not want to purchase a new power supply. Can and where can I purchase a new fan and can I easily inststall it?

THE power fan on my Gateway makes a loud noise after it is on for an hour or so. The power unit is Model NPS-160D8 B. I do not want to spend money for a new power unit. Can I purchase and install the fan only?

    Yes, it is the power supply fan. I have the case open and I can actually touch the fan blade, stop the fan, and the noise stops, then when I release the blades and the fan picks up speed the noise begins. I checked Norton power supply replacement and prices shown were $200-300. I've read many comments about replacing the fan but comments & prices were greatly varied. Could you advise me on a recommended (trustful) replacement power supply?

    Probably not. A new power supply won't be significantly more expensive than a new fan though. And your computer has multiple fans, it may not be the fan on the power supply.

**** is right in general it's not much more to replace the whole unit.

This unit however is a pain due to it's unusual size and high price.

Although typically I advise recycling the old one and buying a new one this is one of those rare cases where the repair would be significantly cheaper.

Two major issues to be aware of if you plan to attempt a repair:

1. size is not the only thing that matters, you must find a fan that within 1/10 of a volt and amp matches this one and it must have as greater or greater airflow

2. orientation is everything. before removing the old fan verify which direction the air is blowing and be absolutely sure to put the new one in the same way as the change in direction may bugger airflow not just for the AC but for the whole unit.

If you're adept in repairs including saudering PCB boards, go nuts and have fun. If not your best bet is actually a stereo repair shop as most computer techs these days don't own let alone use a saudering iron. Stereo repair guys typically sauder new fans fuses and other small components far more often than us computer guys who tend all too often to toss parts rather than repair them in order to save ourselves time and our customers money.

If you open the case, it is doubtful you can touch the fan blade. They mostly are at the back of the case within the silver power supply. If you can touch the blades, it is most likely a case fan you have a problem with. They cost about $10.
If it IS the power supply, you can get one for about $35. I don't know where you live, but any computer store should be able to sell you a new case fan or power supply fan.
One thing you need to be sure of, though, is if it matches what Gateway has installed. They are known for installing hardware made especially for them and generic hardware may not fit in their case.
In that case, Google is your friend--type in the part that you need and your computer model and you'll find what you need.
If you go to a computer store, take the defective part in with you to match it.

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.

You may try to remove the fan, clean it up. Also try to remove the processor heat sink (clean the thermal paste), reseat the processor, put a little thermal paste, that assemble it back. Before you do this, ground your self first(the easier way, hold any metal).

If this can't help,check the capacitor at your MoBo and if you found any unusual look like, it mean you need a new MoBo.

There are 2 basic fans in Dell tower one for the power supply and the other for the Processor. If your computer is not booting then the Processor fan is most likely to be the culprit. What could be happening is that the Processor fan is no longer turning fast enough to cool the processor, so normal the processor when it over heats there is either protection to switch off the computer automatically or the computer won't boot. The best thing is to change the fan and make sure it is working properly but checking on the cables that they won't entangle on top of the fan to impede it's movement. You can easily damage your processor if the fan is not working properly.

I have a sony vaio vGC-LT25E one of the fan is making a loud noise, how to fix it and where i can find the parts.

If it is the power supply fan, typically at the top of the unit making the noise, it is not replaceable by most folks. You'll need a new power supply which are in the $40-75 range. Some private shops will replace the power supply if you buy it from them at no charge, but most big box stores will not. Depending on the brand they are easily replaced. Dell makes theirs unique and tough to replace without modifying the case. Don't know about Sony.
The other fans can be replaced and are fairly cheap. Open the case and determine which one is making the noise. Carefully remove it, take it to your computer repair shop, get a replacement and reinstall. Shouldn't take more than an hour total.
Hope this information will help.
Your response is very much appreciated. Thank you for using Fixya...

If it is the fan in the power supply, replace the power supply.
The case fan is easily replaced. Measure it (in mm) and purchase a new one. The standard fan is usually 40 mm, I think.

Ultra 350 Power supply very loud fan

It's not normal for the fan to be loud, what makes them loud is either a build up of dust on the fan blades or the bearings are going on the fan itself.
If the PSU is working fine then you can replace the fan itself from an identical PSU. It does mean taking the PSU out of the computer and fitting the fan yourself.
Alternatively you can purchase another PSU.

Acer aspire4920 makes loud noise at start up

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.

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.

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 Dell desktop

Any fan that is making noise you would need to replace. There is also never a need to use alcohol to clean a fan. Some computer air or a light wipe down will do just fine.
If you have any other questions let me know.
