Replace the noisy fan before it completely dies...

If it's a one year old system, it isn't brand new.

Most likely, the noise is caused by a bad or dirty fan bearing. When's the last time you opened the case & blew out all the dust? You *may* be able to clean the fan & oil the bearing, or you may have to replace the fan altogether. The 1st thing you'll have to do is identify which fan is the noisy one, then take it from there. Make sure to remove all the dust accumulated on the heatsinks too. Do NOT use a vaccuum!

You do not use oil on the fans as the dust will build up even worse on them.

I use a small artists paint brush, and a can of compressed air to get the duct out my of computers...

Blow the dust out with compressed air, then vaccuum it up off the floor. The reason you shouldn't use a vaccuum inside the case is because vaccuums tend to create static electricity in the hose.

The fan would have to be removed, then you would have to carefully peel up the round label/seal that protects the bearing. A single drop of oil is probably all it needs. Move the fan blade back & forth to work the oil in, then seal it back up again. You can use just about any type of oil...most recommend a light weight oil such as 3-in-1 or sewing machine oil. I see no reason why you can't use motor oil. Believe it or not, I generally use 90W gear oil.

If you have a CD or DVD in a drive when you boot, and the drive is noisy, the noise may be the CD or DVD drive spinning. Optical drives spin while booting if they have a disk in them, and when Windows first starts up, and the led on the drive doesn't necessarily light up when they do spin, and they may spin for some time after Windows loads as well before they stop spinning.
The cpu fan has ball bearings and it should not be making noise due to failing bearings if it is only a year old, but it's possible it and the heat sink for it are dirty, or there is a wire or something else rubbing on the fan blades.

if you really wanted to, you could probably ring hp and try and get it fixed under warranty if its under 1 year old. My not be the most efficient way to get it fixed time wise though.

Tried cleaning/dusting off and the sound grew louder.I just checked and I noticed it's almost 15months since I purchased it.I will call HP whether they might be able to help as the noise is so loud.

You could oil the bearing as jam suggests but in my experince it only helps for la short while. If you get another cpu fan or fan/heatsink combo, note that some of them tell you they're quieter on their packaging, and not all of them have ball bearings on both sides of the fan - if it doesn't say ball bearings with an s, it may have one, and the other is a sleeve bearing, which will cause you problems a lot sooner than two ball bearings or ceramic or fluid filled bearings will.
When you get a boxed set of cpu/heatsink/fan from the cpu maker, the fan almost always if not always has two ball bearings, but it's quite possible HP cheaped out and used one with one ball bearing, one sleeve bearing - if that's the case it's the sleeve bearing that is producing the noise, and it's the one under the label on the side you can't see the entire fan blade on (the bottom side when it's on the heatsink).

As I said in Response Number 1, replace the fan.

A new fan will cost up to $20.00 depending on the size / type , and you know how to use screwdriver...

"Will the phone repairs get it done..."

The $49 fee is probably just the minimum charge you pay for just asking them questions about what you should do - it will probably cost you a lot more for labour plus parts for them to come to you, if they even have someone locally that can do that for them, and replace the fan - $100 an hour or more maybe, minimum charge maybe an hour.


This is not something that requires you ship it to HP.
Any local place that repairs computers and has suitable parts (the heatsink and fan are a standard size) can replace the fan or the fan/heatsink combo for a reasonable fee a lot cheaper and quicker, if you take it to them .

This is not rocket rocket science either.
You could easily do it yourself.

Remove the AC power to your case by unplugging it or turning off a power bar it is contected to before doing anything inside your case. The ATX motherboard is always powered in some places as long as live AC is being supplied to the PS, even when the computer is not running, and merely dropping a screw can short something.

Do you have screwdrivers?
If you do, the fan itself is usually easy to remove - 4 cross (phillips) head screws usually, and you don't have to remove the heatsink if you just replace the fan, or if you get a heatsink/fan combo you don't have to replace the whole combo if the fan will screw into the existing heatsink no problem - if the screw holes are the same distance apart, and the fan is the same depth/thickness, it definately will.
If you're not sure which fan to get, take off the old one and take with you to a place that has lots of computer parts - heatsink/fan combos are more common that separate fans, but both are relatively cheap - you can get either.
......

Replacing a heatsink/fan combo is more complicated, but as I've said, you don't have to replace the heatsink unless the fan or the fan on a combo won't screw onto your existing heatsink.

If you look in your user manual for your model, which is probably already in the Start menu in the Programs somewhere, how to install or remove the cpu fan/heatsink combo is often in that. If you think you can handle that, you just need to get a heatsink/fan combo. If you don't know which one to get, take the combo off and take it with you to a place that has computer parts.

Geez, glad I found this site. I have the same problem. It's annoying to the point that my daughter can't sleep at night because of the noise. I will have to try cleaning it first or will likely change the fan if the noise gets worse. Thanks for all the help here. You all are wonderful people! :)
