I have a Dell Dimension 8200. Recently the CPU cooling fan broke down.
I replaced it with a 90 MM fan with three pins, same voltage.
When I turn the computer on I get a message sayng "previous fan failure. Press F1 to continue or press F2 to go to set up page"
Anyway the fan starts but it seems to run at a high speed and makes noise.
Dell does not offer a replacement for fans or any other solutions.
What can I do?
I very much appreciate any help.
Thank you

Re: CPU cooling fan
Hi...you can press the F2 key to enter setup...and scroll down until the fan is highlited...hit enter and then F10 to save and exit.This tells the computer its OK. you should have plugged the fan in the same pin port the old fan was in. Usually only 1,. If the new fan is not from dell..it may be faster and noiser..or it may be faulty..if you bought it locally you may try to return it. The purpose of the fan of course is to remove the hot air from the CPU to keep it from overheating. If this fan does it it is most likely ok. Hope this helps.. Squipps

As for the green shroud, I would not recommend removing it. The computer case is designed to correctly circulate the air through the system and safely out. As for replacing the fans you can replace them with anything you like, just make sure the new fans are the same dimensions they come in szies 40, 60, 80, 92, 120, 140 and a newer 200 mm form factor so you can just measure them if you don't know the correct size. Next look at where the fans plug in, if it is a three pin plug then they fan's are kept at optimal speeds via the motherboard and bios. So they are already controlled by heat sensors / thermostat so to speak. If they are 2 pin then they just run full speed usually. For the back fan just make sure it is the right size and pin out. You can hook a 3 pin fan to a 2 pin fan plug on the board it will just run full speed all the time. For the CPU fan buy a combo fan/ sink and just make sure the sink is the same as the existing one so it will fit on the motherboard. You could probably get rid of the green shroud if you went with a really high end fan / sink for the CPU but that's up to you. For the thermal paste it is easiest to put a small blob in the center of the CPU and then use a plastic card, such as a drivers license to spread it out to cover the entire CPU, thinly and evenly. Add small amounts if you need to to cover the entire surface. Try not to have a bunch oozing out the sides although it won't really hurt if it is.
Thank for the detail, it really helps... Most people forget about the power supply. If the power supply overheats, it will shutdown. When shutdown, it will cool off then operate again.
A power supply goes by WATT ratings, the average size power supply is now 450 watts for an average system and should cost around $60.
you a ed to re-grease the cpu.
take off the heat sink thats the big metal lump in the middle of the motherbaord under neath it you will find a it will have like a grey or white paint tye stuff on it chip claen it off with some tissue re-apply new grease from maplins or pc world under thermal heat paste the deerer the the better quality the price is between £5 - £10. then put it back together.
The fan settings can be found in the BIOS. On a Dell machine, when you turn the computer on repeatedly hit F2 until you are brought to the BIOS. Search through there until you find something named Acoustics, change the option to run at a lower level. Remember to save the changes before you exit.
you can contact online for techsupport at dell at www.support.dell.com this a live tech support session totally free they have helped me out numerous times keep me posted on how this goes ok best regards mike
hi, i also hav a dimensions 8200 which i recently uprgaded to a 2.8gh, but i discovered there were two versions of this system one which supports a 400FSB and the other 533FSB, these can determine the speed of ur cpu. Like you, I havent been able to unlock my clock speeds in the bios but i think you should be able to get more from ur new cpu by updating ur bios version to A09. check the dell site for more info on how to do this.
All computer fans have a general design. The name in front of "fan" really refers to the designation. You'll see case fan, processor fan, CPU fan, cooling fan, etc. In the case of CPU/Processor fan, some are sold with heatsinks (the metal block sitting on top of your CPU).
The first thing you want to do is make sure the fan is clean. Chances are dust buildup is causing the excess noise.
If that's not the case and you're looking to replace the fan, then you first need to find out the size of the fan. General sizes(diameter X width in mm) are listed on this page:
http://www.svc.com/case-fans.html
Generally, you're looking for something that will match the size of what you're replacing & push enough air at a reasonable noise level to cool the heatsink/CPU. You want to stay in the area of 30dBA max for noise. You also want to see if it has a 3-pin or 4-pin connection.
For example, if you have an 80mm fan, I would suggest something like this:

It's pretty quiet with good airflow. Also, it has a 3-pin connection, but includes an adapter for a 4-pin connection.
