    When I start up my Dell 1525, the fan rattles/grinds, quickly turns off
    and repeats several times before it stops running for about 10 minutes.
    When it comes back on, it is quiet. However, off and on during the day,
    the fan will suddenly emit the LOUD grinding/rattling sounds again.
    Dell Support claims this is normal and that if were a problem that they
    would fix it. Am I crazy to expect that the fan should always run
    quietly, as it sometimes does? The computer is six months old and has
    been doing this for about three months. Now at Level 3 support with
    Dell, who promise to "call me" if they find a solution to my problem
    (which they still insist is not a problem). Not very hopeful there!

    I also have the same problem. I have had it repaired once but the problem seems to have returned. It goes away once the laptop has run for a little bit and the heat pipe has heated up. I haven't tried discussing it with Dell yet but plan to after the holidays. It's now a make or break decision for future laptops. If Dell doesn't have a good answer - goodbye Dell.

    I have the same model 1525 Inspiron. I have had it now for maybe almost a month. I am also experiencing the same problem with it. Or one that is very similiar to yours.
    the fan will run smooth when I have it on for a little bit , but eventually it will run non stop and make this rattling sound like it is not secure or something. I am surprised I am having this problem already. I would not recommend this model to others. I don't think I noticed the problem for the first couple of weeks. I think the past 2 weeks is when it started. I don't know if I am going to let it continue or take it to best buy, but I really don't trust my laptop in the hands of the Geek Squad. I do know one thing, this sound doesn't sound like something that should be coming from a brand new computer.

    I have a Dell Inspiron 1525 laptop that the cooling fan comes on high speed every 2 minutes. Any ideas on reducing thi?s

    I just bought an Inspiron 1525 after reading good reviews - on Dell (obviously) and a few other sites.  I never read one that mentioned the fan noise.

    I have had the computer for three days and the fan kicks on every few minutes and runs for a few minutes.  I work on other laptops (including an older Dell) and none have as noisy fans.

    This fan is way to lousy.  Too bad because I really like the computer.

    I've had my Inspiron 1525 for less than a year and the past couple weeks there has been a buzzing and/or clicking clicking sound that comes and goes, but seems to be getting worse as time passes. HALP.

    I have an Inspiron 1525. I bought this after reading good reviews - on Dell (obviously) and a few other sites. I never read one that mentioned the fan noise.
    I have had the computer for almost one month and the problem started around 15 days back. The fan kicks on every few minutes and runs for a few minutes. I work on other laptops (including an older Dell) and none have as noisy fans.
    This fan is very noisy. I really satisfied with the Laptop except this. i am afraid if this leads to crash of the system. Can anybody help me fix this. is memory upgrade will do. currently I am having 2 GB.

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.

Do you have to follow all these steps to get to the fan???

Just wondering if I am missing something.


Posted on Aug 28, 2009

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.

Dell Inspiron 1525 does not reboot after cleaning out dust from fan.

Take it as a loose connection, go through all the connections and ensure they are making good contact. The only other explanation for this problem is Electro Static Discharge, or ESD. In which case some component is fried.

However the loose connection theory sounds like a winner.

Check the RAM modules, Hard drive and CPU as well as the CPU Cooler fan is connected.

Thanks and take care!

I have a Dell Inspiron 1525 and recently the fan is showing some noise and its heating up the Lappy

Get a can of compressed air and blow out the vents on the bottom and side of the laptop. The fan could just be out of balance with dust. It it still makes a noise afterward, the fan itself may be going out and need to be replaced.
