As fans with ball bearings in them operate, they gather dust. this dries out the lubricant in the bearings track. normally cleaning the fan would suffice to restore effectiveness just run a vacuum over the fan on a regular basis to stop the dust building up.

if you have added lubricant to the bearings you may find that more dust is now sticking to the dust that was already there reducing the fans effectiveness even more and causing more noise.

another possible reason for the increased noise is that when lubricating the fan, depending on how you did it, you may possibly have bent the fan's axle slightly again increasing vibration and noise.

personally I think it unwise to add lubricant to a ball bearing track such as that on a cpu fan as lubricants vary in viscosity and suitability for use and I wouldn't know which one to buy. If the axle has become bent, I believe it is possible to have it straightened but with the price of fans being so low I feel your best course of action would be to replace the fan and then make sure that your new fan doesn't get clogged.

I have an acer aspire ax5900. The video card fan vibrates loudly for the first 10 minutes after start up. I am told I need a new video card. Is this correct and where is the best place to get one?

Your Acer Aspire, like any other desktop computer system, contains fans inside the case to help vent the heat generated by the internal components.
These fans generally operate quietly and reliably, working in the background to prevent your computer from overheating.
A fan that sounds excessively loud could indicate a problem such as overheating or loose internal components, or it could simply be a normally loud fan.
The key to differentiating between the two involves looking for additional clues from your computer.
Normal Operation
Due to computer configuration and build quality, the fans in some desktops sound louder than others.
Depending on what other brands of computers you've owned or have had experience with, the fan in the Acer may sound louder, when it's actually functioning perfectly.
The fan will run to keep the inside of the computer from overheating, so periodic runs are normal. If the fan runs for long periods or very often, you may have a deeper problem.
Fan Damage and Overheating
A fan can sound loud due to damage, such as broken blades or to a build-up of dirt that impedes normal operation.
This dirt, as well as normal wear and usage, can wear away the lubricant coating on the fan's internal shaft, causing the blades to make excessive noise as they turn. In many cases, a loud fan indicates that the computer is overheating, causing the fan to run more often than usual to try and cool the system.
Depending on the types of components and upgrades within your Acer computer, your current fan may be too small and weak to handle the heat output, and require upgrading to a larger, more powerful fan.
Take note of when the fan turns on and how long it runs to determine any distinct patterns, whether if it occurs only during certain processes or programs.
Your computer's CPU generates a large amount of heat while in operation, so programs that require large amounts of CPU usage may trigger the fan more often.
Watch for additional signs of overheating, such as sudden shutdowns or computer crashes. Check inside the case for signs of other components touching the fan and causing vibration noise.
Do not overtax the CPU by opening numerous processor-intensive programs at once.
Check that all screws, cards and wires are securely fastened and away from the fan.
Keep your computer clean inside and out, to prevent the build-up of dirt on the fan blades or air vents and minimize the threat of overheating.
Apply a drop of oil to your fan's shaft to give it proper lubrication and smooth, quiet rotation of the blades.

My emachine t1090 is making extremely loud whineing noises( like my bathroom fan when it is dirty). I took the casing off of the machine and cleaned it with compressed air, alos took casing off of the fan...

you have a ball bearing fan, after awhile, the fans ball bearing move around, thats were you are hearing the whining noises. All you have to do is replace the fan with the high piched sound.
The fan is $2.99USD and $1.99USD Shipping, no tax. Fan Total = $4.98USD

Have a nice day

I Have a Gateway GT5622 computer, recently the CPU fan has been rattling, I was told to lubricate the ballberings, which I was given instructions to do and I have the oil to use. however noone knows how to...

The fan is usually either screwed to the heatsink. They might have used some sort of epoxy to hold it in place. Usually when these type of fans start making noise they need to be replaced at only a couple bucks its worth it.
I'm not sure that you could lubricate the bearings they are probably a sealed system.

Dimension 3000 gets noisy when the weather gets warm

I'll have to guess exactly what gets noisy. I'm afraid the crystal ball is in for a service :-)

If you put your ear close (NOT THAT CLOSE) to the rear where the cooling fan sits is the noise much louder? If so, it could be a fan about to dry out and fail. Many of them are cheaply built and don't use a ball type bearing. I don't normally recommend this trick but what I do is inserta plastic probe or the end of a plastic spoon just inside the grill just enough to stop the fan from spinning when you switch it on. Switch on the computer with the fan stopped and if the noise isn't there you have a fan requiring replacement. Don't leave it on for anymore than a few seconds. It's a cheap and nasty way of doing things but us techs tend to prefer this approach.

If the noise sounds internal it could be a hard drive with bad bushes if it is back up all your data and replace the drive before you lose all your info. Or possibly the fan which cools the CPU is heading to meltdown. If it is the cause of the noise, replace it immediately.

Another trick I'll let out of the techs bag is to get hold of a short (18inches) piece of rubber tubing. Hold one end near your ear and the other near where you think the noise is coming from. once you find the right spot you'll know it's the right one, believe me. Just don't jam it into fan blades even the small cpu fans can cut your finger open. Also check for larger cooling fans dotted around the case.

I'm a betting man and I'll lay odds it's the power supply cooling fan at the rear of the computer near the power inlet.

Dell Demension runs great but loud fan noise that takes a long time to shut down. What going wrong?

I had a similar problem with excessive fan noise on my Dell Dimension 5150. The solution was to replace the worn heat sync compound that was between the cpu and the heat sync itself. (£0.99 ebay)
