The CPU fan in my Dimension 3000 stopped running, shortly after I vacuumed out the dust from inside the computer. I purchased an off the shelf fan that powers directly off the power dongles, and have been running OK, except that the Dim 3K has a fan monitor on the fan, and gives an error each time you turn the computer on. I purchased a "new" fan on eBay of the same model that came outta my computer (I say "new" becuase the fan I bought actually is even older than the original that came in my computer). I installed it, and it does not run. Weird. So I bench test the "new" fan, and it runs fine when powered directly off the power supply - AS IT TURNS OUT, SO DOES MY ORIGINAL FAN!!! So, conclusion, the problem is not the fan, it is the fan power coming from the motherboard. So the question is, other than the socket where the CPU fan plugs into the mother board, is there a fuse or other connector, or a software switch I can set, that controls the power to the fan?
I cannot seem to find any setting in the BIOS for the fan, I have looked pretty hard. It's not that big a deal, getting an error on reboot. My only concern is that the original fan is rated at 120 CFM, while the highest off the shelf model I could find was 82 CFM. Now when I feel the CPU heatsink (with my off the shelf fan running off the power supply), it feels cool to the touch. So I think I will ignore the error message at boot up, and hope for the best.

You can turn the fan monitor off in the BIOS, or at least disable the error message. There is no way to repair the faulty connector in all likelihood. There MAY be an unused connector on the board for an optional case fan. If so you could plug your processor fan into that. I would be comfortable running a fan directly off the power supply, exactly what you did.You can turn the fan monitor off in the BIOS, or at least disable the error message.

I agree with both of you. As long as you are not experiencing any heat event (shutting down and rebooting) just ignore the error message. If the fan is on and running at a fair speed, you shouldn't have and problems. Now should you start to have heat problems, don't boot the computer until you have a larger CPU fan in place...and too you may be able to add an additional fan to the system for reassurance. the added noise is worth the security of not having a CPU meltdown. Those large 120 are very quiet and move air, if you can find a place to hang it. Good luck, hope this helps. please leave rating -thank you kindly

Make sure u can open the casing well to expose the interior parts without causing any damage. Then by close look at the processor area , that is where the heat sink is located. Normally the dell dimension 2400 has a green channel shaped structure that acts as a passage for the air that enters in and out for cooling the heat sink. It has a locking parts that slides into the casing back by slight pressing to the back of the casing just behind the processor area, be so observant to notice the locking parts. then the fan is just fixed behind that green " channel like" and its fixed on the rear side of the casing,
This is what happen to me also, but after i do some clean into my fan processor, fan graphic card, and do vacum inside my computer ( because has too much dust). Too much dust also can make your pc performance going bad.. settle about cpu performance.
Regarding you cant play mkv file and other video format. Did your computer has a software to make all video can run that we called codec code? Try to install it and play it. Maybe this software can help This is a link to download the codec code. Codecs com Downloads for Lite Codec Pack 10 2 Full Standard and Basic
Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail. A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust. Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.
You can clean or replace the fan.
Get the manual from www.dell.com/support You can download it free and look up the fan repair instructions.
Hope this helps.
Your CPU may be overheating. Open the case, vacuum all the dust and
inspect all fans: Power Supply, CPU, Chipset, Graphic Card etc...
If all are operational then maybe the CPU heatsink compound (grease)
has dried up over times, and need a fresh new replacement.
Download a copy of Real Temp 3.60 and run it continously to monitor
the CPU temperature in real time.
That's because it heats up more easily and faster, which usually makes the fans spin faster and results in being noisy. Have you ever cleaned out the interior of the computer? If not, or if it's been awhile since it's been done, then buy some canned air for dusting electronics, open the side of the computer case (while it's not powered ON), and blow out the fans and the heat sink. If you get alot of just clogging up the heat sink, then it will not dissipate heat correctly; which results in the fans running more often. It that doesn't help any, then I would try to figure out if one of the fans is making alot of noise because it's going bad. You can find replacement fans on ebay, or at local electronics\computer shops.
has the cooling fans been cleaned lately?PC's shouldn't be noisy to the point you're asking for advise about it. Is it a grinding noise, a clicking noise..more info plz.
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)
This happens when it is getting too hot inside your computer. Take a can of compressed air and blow out the dust inside the computer, around the heatsink, fans, and any vents you see. Follow the instructions on the can for maximum efficiency. This will allow your computer to run cooler and the fan won't have to run on high speed quite as often, if at all.
If your fan is not turning at all then it is probably dead, the bearings are likely clogged with dust and such. The PC is shutting off because of heat buildup on the processor chip. You need to do an Ebay search for your model and order a fan right away. Continued running of your sysem without a fan will kill the processor and motherboard. You should be able to get a replacement fan for your computer for less than $15 including shipping. Your local computer store may have one to fit your system but they may charge more for it. To change the fan is very easy, the left side of the case will come off your system, right under the power supply is the processor and heatsink and the fan. Disconnect the old fan and reconnect the new unit.
