Question about Dell (6F858) Cooling Fan
Fan makes too much noise... What can I do???
If this is something that started recently, then start by taking the fan out and cleaning it, also clean the heat sink while you're there. Sometimes a dust will build up on or around one blade more than the others and cause the fan to wobble creating excessive noise. Also check the blades for any nicks or cracks, and check the fan blades for excessive play, the play should be minimal. If there are nicks, cracks or excessive play in the blades, the it too cad create the noise. nicks can be taken out by shaving of the raised part, and sanding the area smooth. Cracks or play will require fan replacement.
Now if this has always been this noisy, it may be that this is the normal amount of fan noise for this machine, I could tell you if I could hear the fan. You can try replacing the fan, some fans are louder than others, even the same make and model. You can also try the tune up from Dell's support site for your machine. I placed a link bellow for the application. Some tune ups have fan patches that decrease the noise level, this one doesn't give specifics to what it fixes, so give it a try, it may work for you. If not, then you can always contact Dell and have them take a look, I imagine this machine is still under warranty. Anyway, give these a try and let me know.

Same issue, had a loud as hell screaching noise coming out of the machine suddenly. definitely the cooling fax, I squeezed the case and seemed to have actually stalled the fan, the quick fix. Took the 1525 apart, no fun task... had to remove the main board assembly and everything above it. Found a nice chunk of dust on hte heat sink, but it was not interfering with the rotation of the fan blades. Tried manually spinning the fan and definitely noticed resistance and contact that was obvoisuly causing the shrieking noise at higher speeds. Was going to call it a night and head to radio shack tomorrow praying that I could find a replacement when for the fun of it I tried stretching the fan casing. Suddenly silence and free spinning!!!
The Sunon brand MagLev fan that came with this has a 3/4 plastic composite body with a very flimsy adn maleable back metal plate. Try prying it up a bit and the blades should spin freely.
Ongoing risk, if its so easy to bend, and the fan assembly is under the case in a place where you likely cup your hand and squeeze to carry the machine, we will likely inadvertantly squeeze this area again and cause teh same problem. I'm not willing to put this back together another hour ordeal, and pray that my wife won't squeeze the charmin again...So as mentioned off to radio shack tomorrow hoping they have something on the shelf.
Hope this helps.

Good luck. I have this model, brand new, but Dell support had me send it in for repair, didn't repair it, sent me a new pc, worse than the first and with a defective wireless card as well. They refuse to let me return it. Do not buy this pc.
