Fan on Dell Inspiron 9200 was making a lot of noise

posted in: Fan Makes Noise | 55

I have a dell inspiron 9200 and about a month ago, when I turned my PC on, the fan (not hard drive) started making this huge noise and the whole computer slowed down. After taking the whole thing apart (I was so proud cos I’d never done that before…I did desktops but never my precious one and only laptop!)….and having cleaned the fans completely, the noise still persisted. I tried doing everything from windows too but nothing helped.

I found an online forum like this and it was such a simple stupid solution…….You can make your fan go at a higher speed if u find ur laptop over heating by pressing Fn+z (Keep Fn pressed and then hit z). Do the same to slow it down.

This solution is for a Dell /any machine which has a Fn key. So try it out. If you are lucky like me, it was a error on my part. I play PC games so Fn is right next to control (shoot) and next to Z (lie-down/crouch) for my FPS! So I must have hit that combination in terror when a monster jumped out at me or something.

    Thanks so much for this tip! It worked like a charm for the same problem on my Inspiron 9200 as well. The only other way I’d gotten it to stop was to shut down and let the machine cool off before rebooting; very annoying!

    So thank you, thank you, thank you!

    Brilliant… thanks so much… had the same problem.. even though I have it on a wire baking rack!!

    thank you .. thank you!!!

  3. incognito

    oops..
    only works for a few seconds though… I have an inspiron 6000 and it’s not even over heated.. will have to keep looking..
    thanks anyway.

  4. Fantastic, thanks so much! Really useful tip. Works on inspiron 1300 too.

  5. Thank you so much!!! I was about to reformat my HD if this tip doesn’t work!!!

  6. ok guys im having the same problem but not sure if making my fan go faster or slower. Like the original poster i have a problem where my computer slows down when My fan starts making noise. I recently started to play a FPS on my pc and it was slow as shit.

    Function+Z does make the fan go but how do i know if its going faster or slower?

    I have a gateway m305CRV laptop and just replaced the heat sink because the fan would run a lot. The new heat sink is just as noisy as the old one. The constant white noise is driving me nuts. How do I get the fan to throttle down? Please help!

    I have a Dell Latitude C840 and the fan is making noice. I bought a new fan but now I need to know how to take the laptop apart and replace the fan. Can you help me do this?

    Thanks

  9. OMG! That was ridiculous… that fan noise was driving me insane.. and my girlfriend too… ridiculous… thanks a bunch

    It’s good after press Fn+z,the fan stop and without noise,but it just can maintain some seconds or minutes,(depends on the hot of the computer i think).after the fans running in a high speed and make a big noise also.how to solve it.

    Thanks.

    YOU DO NOT EVEN REALIZE HOW MUCH I WANT TO HUG YOU RIGHT NOW! xD This is amazing…I thought I was making my computer do this, and that I broke it or something. Now my iPod can have a break from blaring, and overriding that ridiculous sound of my stupid computer. Thanks! :)

    Hi. Having a lot of problem with my Dell 9300. Fan running and very slow. I did the FN Z thing and that worked. Don’t know about the speed yet. I paid $35 for someone to check it and they told me they did not know what was wrong. It still runs slow so I will have to get it checked but these repair people don’t seem to be able to repair. Its unreal. Thanks at least the fan stopped running. Now i need to speed it up.

  13. Barbaracape

    OK, WOW, thanks so much. I just checked and considering I was a hair away from throwing the computer out and buying a new one, it is much faster. Its amazing. THANKS SO MUCH ! ! ! I have been pulling my hair out for months. THANKS.

  14. Pamela

    You are my hero. I spent months on this random fan problem with Dell support! My prob (Inspiron 9300) was the fan would constantly and randomly kick in at high speed for no apparent reason. Dell replaced both my fans and the motherboard and it kept happening so they told me I should reinstall my OS (didn’t do it). I found this post and then confirmed it here: http://comcap.free.fr/c640.html These guys say that what Fn+z does is force the BIOS to re-read the temperature. That’s reassuring, because it means you’re not turning off the fans permanently. Dell. I’m getting a Mac next time anyway. Thank you from Pamela in Paris! Oh, and I sent the info to Dell tech support. Duh.

  15. Thanks Man

    It works, greate !!!

  16. Thanks man, you saved my life! I paid a lot to get the fan cleaned and it still made noise. So much it drove me crazy some times. But this thing works eerily on my HP laptop. I cant thank you enough

  17. wow, instant fix to what i thought was going to be the last straw for me getting a new laptop. thanks!

  18. ph0dacbeit

    i’m having the same problem. Sure it shuts the fan down,but monitor your cpu speed and load. I am always running at 800mhz it never peaks to 1.73ghz and for some reason at idle cpu load is at 100% so it’s laggy as hell.

  19. Craig Toomey

    Dude. You’ve fixed it. This is simply amazing.

  20. this is not a fix for me- as some of the others my computer isnt even overheating the fan is just turning on at random times and then the computer starts lagging for no reason- this is right after i turn it on- and im just checking my email- sometimes it does it sometimes it doesnt. but i hit fn+z and it shuts off for 5 seconds to a min and then turns back on. very weird- if i find anything else i will come back and post it for those others who have the same problem as me.

  21. Man you deserve the craziest hug from me. It saved me hell lot of trouble. I just dont know how to thank you. Sharing is indeed caring.

  22. It’s all very well speeding up and slowing down the fans to stop the noise, but the fans are there for a reason and if you slow them down/stop them just to get rid of the noise the laptop will overheat (like mine did) and break something (the video card in my case). Is there no fine oil spray or something that will actually stop the fans being noisy without stopping the fans?

  23. Shingyyy

    Please someone help me with my nasty INSPIRON 9200. The fan never stops running after 5 minutes or so. I troed Fn + z stuff but it only works to speed-up but never speed-down… I’m thinking of replacing with a new fan but I don’t believe it is a problem of hardware that’s making problem but it is the matter of thermostat or some software which detects the temperature inside… I would really appreciate if someone could let me know how I should solve this problem!

  24. Amazing! Same problem with my Inspiron 9200 for months. I was at the point of giving up and buying a new laptop as had tried everything. Such a simple solution. Cheers!

  25. Shingyyy

    sparky,
    Thanks for the feedback. What did you try to sort this out..? I do something else which you didn’t try before I come to the point to buy a new laptop….
    Shingyy

    Further proof that my BIOS absolutely despises me.

    Much obliged for the help, especially from the comments.

  27. Frank303

    Thanks, Inspiron 9300 fan problem solved. Just hit Fn+z.
    Who makes this function and not print it on the keyboard?

  28. It seems there are much people use Dell Inspiron 9*** series Laptop.I am satisfaction with this computer’s speed.that’s good.

  29. Unfortunately, this didn’t work for me…

    I have a Fujitsu Siemens Amilo L1300, and the fan is going absolutely crazy. It has been loud and coming on every second minute ever since I got it (about 3 years ago). But it has gotten louder and louder and lately it has taken to never stopping whilst being turned on. It is driving me insane. I wear earplugs because the noise is so distracting, and my fellow students run for their lives when my dear (and confused) Fujitsu Siemens and I wander towards their desk 3 minutes before the lesson starts. *sigh*

    Is there any program I can download to be able to control what temperature the fan starts on or something like that? Or should I buy a fan controller of some sort (or a whole new fan? But since it has always been loud maybe buying a new fan won’t save me..)?

    Thank you in advance for any answer that might help!!

    I have a Dell Inspiron 9200, works like a charm
    Fully customizable
    But remember if you want longevity you better keep that puppy cool.

    Just a reminder also
    CHECK YOUR FANS AND SCREENS
    I had a good friend who was complaining about his ‘NOISY’ Dell computer. When I dropped by to look at it for him I was shocked, not really I have seen way worse it just sounds funny, his computer was full of crap and dust. So a little compressed air, with a ground strap on of course, and 20 minutes later that DELL was as quiet as a church mouse.

  32. I tried what you’ve posted. Though I don’t know if I have the same problem as you. I don’t even know when I’m pressing fn+z if it’s even changing the speed of my fan lol. My issue is a little bit different. Though I’ve been told by many people that they think it’s my harddrive I think it’s a little bit different. I own a DELL Inspiron 1501. It’s about a year and 5 months old. There at first it was used constantly 24/7 even left on a few days in a row for downloading, which is why I think it’s a fan problem. But anymore my laptop HAS to be on a flat surface, and I mean FLAT. It can’t be tilted what so ever in a weird way or else the left side of my laptop, where the fan is swirls and whirls at a high speed, and blows more air then usual. Usually the only way I can fix this is if I put my computer into sleep mode or shut it down which totally stops everything, and I sit and wait a few moments before turning it back on.

    Now if I’m just sitting here, and have the laptop laying on a flat surface it’s fine, I have no problems with it at all. But if I tilt it my computer just starts to vibrate and where the fans at makes a weird grinding noise and more air ends up pushing out from the vent hole.

  33. OK this works good and well but what do you do when you want to speed the fan back up?

  34. Hi, I’ve been trying desperately to find out what is wrong with my laptop all of a sudden and no one seems to know the answer! Just a month ago, my laptop fan started making a lot of noise, and blowing out a lot of air – like it’s overworking.

    I tried pressing FN+z but it didnt work on my lap top. I have a Dell XPS M1330.

    I’d be so grateful if someone can help me fix this! I’m reluctant to use my lap top now because the noise is so annoying :-(

    Thanks in Advance,
    SiSi

  35. Erwin Bemelmans

    It worked for me, and my inspiron 9100. Thanks.

  36. Thank you for sharing the Fn z. Only the noise will go back after a while. My Dell laptop is only 9 months old. I cannot see dust from outside. Do I have to open up the laptop and check for dust?

  37. Great advice.. it worked on my dell inspiron 9300!

  38. hey i tried the fn combination..but it didnt work for me..i have dell 1420 and my fan is making lot of noise

  39. thanks
    it worked on my dell inspiron 6400 [30 months old]

  40. Brummy Rob

    I have an Inspiron 9100 and have bought new desk top to replace it at work as the speed had become such a problem and I gave up on resolving problem after I had tried everything and also the IT guy at work couldn’t fix it.
    Well tonight I dug it out for another try whilst watching Taken (great film by the way) and after reading this article I cannot believe I have fix the problem so quickly and easily, I am sure gameplay keys in Battlefield 2 was to blame.
    Thank you so much!

  41. Yup. Worked on my Dell Inspiron 2200. Thanx!

  42. romanita

    you’re my hero! I really did not believe this would work! cheers!

    SiSi and others with a Dell XPS M1330:

    My wife’s M1330, like many, maybe most/all, runs hot due to inadequate video card cooling. If your video card fan is going bonkers trying to keep things cool, try a notebook cooler pad to put the M1330 on. The first and cheapest pad we found at Fry’s knocked down the temperature by 15-20 degrees. So now the pad is noisy and the M1330 is quiet. Oh well . . .

  47. Hi Guys,

    This website is great!

    I have a dell Inspiron 9300 Core2 2.0GHz, 2 gig RAM, 256mb NVIDIA Geforce 7900GS, with a 160 gig HD.

    The computer still works and turns on normally and I can do normal work things with it but I cant play games properly. When I do play games the frame rate is very low.

    I found out that there are 2 fans on the this laptop. When looking from the top of the computer, like you would be working on it, the left fan is for the video card and the right for the CPU.

    The CPU fan still works, and I downloaded a program that forces all the fans to work at thier maximum. That did make the CPU fan work hard but the video fan didnt budge.

    So I thought that the GPU is overheating and that the low framerate is protecting GPU from damaging itself.

    Now the problem that I have is that I need to find replacement fans, I’ll replace both fans, and then I need directins on opening and replacing the fans.

    Thanks so much!

    John
