Question about Dell Mini Fan. Dimension (W x H x D) in. 8.7 x 12.2 x 8.2 in.
We have a Dell Dimension 4700C too. We had it on a 3-year warranty and the only problem with it was that from that to time it would become abnormally noisy, too noisy in fact. Dell sent a repair guy twice, and they changed the heatsink/fan assembly unit both times, and the third time we did it ourselves (it's not that hard to do), but here's the thing, we noticed how DUSTY it was when it came out, we wondered how it even worked with all that dust. So, now our warranty has expired, and guess what, the computer started making that terrible racket again, so this time, we opened it, armed with the vacuum cleaner and a can of compressed air, gave the whole inside of the computer a good once over, removed the heatsink/fan assembly and cleaned it thorougly (you can't do this unless it is out), and it worked like a charm, can't even tell the computer is running. Hope this helps.

Wife's Dell Dimension was noisy. Noticed the shelf it was on was leaning a bit. Moved computer to a perfectly level surface and now the Dell is very quiet. Check yours by placing a spirit level on top of the case. Check that it's level both front-to-back and also side-to-side.

Identify which fan you got 2 maybe 3 or 4.
A fan for the power supply that removes heat from the over all system, a fan on the case that also removes general heat and one on the cpu.
The core of this fix is...wait for it...hold the excitment...da... da .da da. WD40.
If it's either the power or case fan try and remove the fan itself, the centre hub will be covered with a simple sticker, removing this will expose the shaft the fan spins on, squirt some wd40 here, if the fan can be attached and actually powered while you do this it will draw the grease down the shaft, otherwise if it's off it will just get a little. Generally this will shut the thing up for another year or two.
Same a appliesto the cpu fan but usually you have to remove that from the heat sink it's attached to get at the stick/shaft.
WD40 is pretty non conductive so you can be kinda sloppy with it, this is my experience anyway. But you don't want to coat your entire computer in it is highly flamable, aka try and just get it on the shaft of the fan.
If your worried look at the hardware store for some other type of lubricant spray, squirt bottle, pretty much anything will do the trick if you can grease up your fan.
