Identify each of the fans in the chassis in terms of its square size and thickness, is it 3 wire or 2 wire, confirm its voltage as 12 volt and what current it draws if it tells you on the label. Unfortunately due to the nature of Dell chassis design it its normally difficult to fit anything other than the standard size in the space provided and they mostly use either 80mm or 120mm fans. You than need to look for replacements with the highest airflow in cubic feet per minute (cfm) versus noise (dB). Zalman are normally credited with producing the quietest fans and if you can replace a 80mm with a 120 then you could use a separate speed controller to reduce the speed of the 120mm fan to a slower revs as they by default have a higher cfm (bigger area). This is where the current comes in as 120mm fans generally draw a higher current at full speed but you can normally get away with 1.5 times the stock fan current.

Beyond this requires some serious case mods but the most critical is the CPU fan. If the PSU is the problem them some Dell cases will allow you to fit standard models with bigger temperature controlled fans.

First you need to tell us which fans are the loud ones you are talking about but normally it is the cpu fan. Any computer parts store should have various fans available for different chipsets.
This link will take you to a page to find a fan. You will probably have to get the model number off your current one to find an exact match

Card fan makes noise

Turn off your computer, if your familiar on how to open-up you CPU do so, then,

Try cleaning the fan.

What you can do is clean it with a bush (ex. paint brush-a clean one) or a clean cloth.

you can also try to remove the fan then at the center of the fan there's a sticker, you can safely peel it off then you will see the center of the fan, you can apply machine oil on it, then put the sticker back. Then turn on your computer, let's see if you still has the problem :)

I know that there are many of these types of system boards out there, What I would do is contact Tiger Direct either in Canada at or in the US at and send the sales team an email [email protected] - They will usually find anything that you need and have very quick and reasonable shipping rates.

Give that a try and see if it works for you.

What diameter is the processor fan?

its not a standard diameter for a pentium4, ime not sure of the diameter as dell does not list it and the actual fan is on the case , ported to the pentium4 cpu covered with a heat sinc. Your best bet is to physically measure it or take it with you when you buy a new fan. If you have the outside dimentions ,the correct screw hole pattern and it fits under the plastic shroud, you have the correct fan..
