Running an Acer Aspire ax5900. The video card fan vibrates loudly for the first 10 minutes of startup. I'm told I need a new video card. Area is clean and dust free. Where is the best place to find a...


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.


Troubleshooting 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.

Solution

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.

Laptop making loud fan noise like its overheating,


Go buy a can of compressed air and blow out the fans and vents. That should get it running quiet again.

When I plug the unit into power, the CPU fan runs very fast but no boot, and then when I press power on the fan slows down and the PC boots normally. It shuts down in about 30 minutes with no sign of...


Sounds like you are overheating. One way to tell if it's overheating is you say it will run for about 30 minutes then shuts down. When it shuts down try rebooting to see if the boots successfully. If it fails to boot successfully right after it shut down then you are probably overheating. If you wait awhile to let it cool down for 30 minutes or so and if you reboot and it does it successfully you definitely have a overheating problem. If I remember correctly all those compaq sr series have loud and fast running fans. Computers overheat because of three reasons for the most part: 1) A fan has stopped working. 2) The Thermal Paste on the CPU and Heat Sink has dried up or is not thick enough to keep the unit cool. 3) Dust has clogged the fan vents and inside the computer. Fortunately for you desktops don't have to be completely disassembled like laptops to get to the fan, CPU and heatsink. Just pop the case and you'll see the components attached to the motherboard

I have a Dell Inspiron 1521. 6 months ago the fan makes a really loud noise when the laptop has been running for a while. It went in June to be looked at because my computer messed up and they had to redo...


Yes, the fan can be definitely be replaced. You can actually get a replacement fan for your computer at The Laptop Fan Shop online for about $22. The process of changing a fan is quite simple, so you should be able to do it yourself to save on labor. Although, if your computer is still under warranty you should contact dell directly at 1-877-694-3591 to see if they can replace it for you for free.

Screen not displaying. and fun starts and stops, remains stand by when restarted the fun runs and stops stand by.


hello there,

I got the same problem but it came gradually...

In fact for a full month when I first boot the computer, the fans runs, no extra beeps, the light blinked correctly but no bios at the screeen. I remarked also that the fans run full speed doing a lot of noise. Then I stopped the computer and wait 2 minutes and then it always works correclty at the second boot with the bios screen appearing. Also, the fan calm down after 1 second with less noise. So when I start the computer and hear that the fan calm down with less noise after 1 second, I know that the computer will boot correctly. That happens always at the second try after waiting 2 minutes. But since yesterday, the fans never calm down and the noise still remains high with no Bios at the screen. I'm suspecting the Power Supply...

i hope my i dea can help you.

Loud Noise on laptop when booting


Most likely it is the POST throttling up the fan to 100% during boot up. Then it switches over to ACPI(?) power manangement and Windows manages your fan speed to extend battery life.

Suggestions:
Go to Dell Support Site https://support.dell.com/support/supportrequests/create.aspx?c=us&cs=19&l=en&s=dhs
Download the latest BIOS updates and run it.

If it continues, try a can of compressed air, and breifly blow out any debris from the system fan. Bits of paper and critter-fur can get sucked up into the system.

I think the fan is making a super loud grinding noise.


I would not recommend this. You could fry your cpu and then you would have no notebook. If you are going to open the notebook make sure there is nothing interfering with the fan. The fan can be replace. Take the fan out and try to replace it, if needed. Do not run the notebook without a fan.
