    Dell 5150 has started making loud fan noise. I dusted the entire inside and it didn't help. Do I need to replace the fan, and if so, is it difficult?

    I have the same issue. Everyone tells me to replace the goo between my heatsink and fan. That would be great if I knew what a heatsink was and what type of goo they were referring too

If the fan is only making wind noise it is ok. If it is making matalic noise replace fan. It would be a good idea to clean (blow)out the dust and dirt for the inside of the computer at this time.

Should my fan run all the time on desktop dimension


Yes, the computer case fan, and the Power Supply fan should run constantly.

If this is in reference to a Dimension 5150, there is one computer case fan in the front. This fan pushes air through a plastic tuned port, (Shroud), onto the Heatsink, which sits on top of the Processor.

http://support.dell.com/support/edocs/systems/dim5150/en/sm/index.htm

The above link is to Dell Support, and the Service Manual for the Dimension 5150.
Technical Overview shows the inside of the computer.

Processor's have a thermal limit. Once they exceed this thermal limit, or temperature, the Processor turns off. (BIOS turns it off)
This is a Fail safe feature built-in to keep the Processor from burning up.

Desktop computer fans run all the time, unlike laptops.
However the fans should not run at full speed all the time.

If your desktop computer fan sounds like a 'jet engine' constantly, there may be internal hardware problems, for one.

1) It may be that the thermal paste has dried up.

The top of a Processor's case, and the bottom of a Heatsink are not perfectly smooth.
There are 'Pits, Hills, and Valleys'.

The above mentioned imperfections cause a void. This void is an air pocket.
Air is an Insulator, not a Conductor.

Thermal paste fills these voids, and is an excellent conductor of heat. Transfers the heat from the top of the Processor's case, to the bottom of the Heatsink.

Example of a typical Heatsink/Fan combo,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3451342&CatId=493

The Heatsink is the finned aluminum looking object under the fan.
(The Dimension 5150 does not use this kind of Heatsink/Fan setup. I included the link to show a typical Heatsink. The front computer case fan, pushes air through a plastic shroud which encases the Heatsink, in a Dimension 5150)

Solution is to Thoroughly clean the top of the Processor's case, and the bottom of the Heatsink, and correctly apply fresh, new thermal paste. (Average cost of thermal paste for this application is $6)

[NOTE*
Observe Anti-Static Precautions!]

2) If the inside of the computer is dirty, as well as the inside of the Power Supply, this will also cause the cooling fan/s to race at high speed.

Solution is to use a can, or two of compressed air for computers, and clean the inside of the computer, (Especially the fins on the Heatsink), and the inside of the Power Supply.

[Again, observe Anti-Static Precautions]

Dell dimension 5150 the fan is really noisy and sounds like its going full blast all the time.we can hardly hear the telly over it.


Your fan is most likely in need of a cleaning, or straight out replacement. You can remove the retaining screws and pull the fan out as a complete unit and blow it out with a can of compressed air. If the noise is a high squealing sound, then I would purchase a replacement fan and install it. Fans can be purchased from Ebay, just remember to check and make sure that you are ordering the correct fan (case or heatsink) before you commit to buy.

My DELL Dimension 5150 fan is making a great noise, how can I fix it?


Turn the computer off.
Disconnect the AC power.
Remove the side-panel.
Buy a can of compressed-air, and give your computer a "blow-job" to remove dust from "everywhere", including the fan(s).

If you still get noise, then it's time to replace the fan.
Take the computer to any computer-store, so that they can sell you a new fan that matches the current fan.

Where is the microphone on a dell dimension 5150?


You have to buy an external mic and put it in the sound card - the machine doesn't come with a mic installed on the unit. Some lap tops do but desk tops do not.

Dell dimension 4700: top fan makes a lot of


some fans are just loud, they tend to speed up and get louder when the computer heats up, it keeps it from over heating... if it always runs hard and loud the internal thermostat could not be working right.

My Dell Dimension 5150 fails to turn on when i press the main power button. It makes a jarring noise about five times and then nothing, no connection with the monitor, no activity. Any ideas?


My first inclination would be to check the power supply. There is a fan within it. If it is not turning and pushing out air, the supply will immediately fail when it gets hot. Upon starting PC, you should hear that fan and feel air coming from the vent holes. I would also check to see that any case fans inside are clear of cables. Hard drives and other media drives could also make the sound, but they shouldn't prevent PC from starting.

Noise from unknown source


Grrrrrrr - Could be CD running, Could be Fan on the CPU, which if not fixed will kill you main chip, could be power supply fan, check in the back and see if fan is turning consistanly ( I think that is how you spell that) If you know how to remove covers, take side off and look at fan on the CPU or other fans and when you hear the Grrrrrrr se if you can tell where it is comong fro, also some hard drives will make a sound as they get older.. Good luck....

Dell Dimension 5150 no sound - please help


You should be able to download the original driver files from Dell Support Drivers & Downloads.

However, this may be worth a try:
Go to Start --> Run, and type in services.msc.

A window will pop up with a list of services. Scroll down to Windows Audio. Right-click
and click on Properties.
Make sure that "Startup type" is set to automatic. Also, make sure, under "Service
status," start is selected.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
