computer fan noise driving me crazy, need help please!

The facts:

Edit: Still looking for help please!

- This is my computer: I haven't changed anything about it really since I bought it a few years ago, so all the specs listed there are still accurate.

-The fan that's making all the noise is a small fan in the front of my computer tower, just below the power switch, which seems to be aimed towards my hard drive. However, I feel very little air being generated by it. A (long distance) friend who knows a lot more about computers than me has told me this is not a majorly important fan and I could probably get by without it for a while.

-The fan that's making the noise is not the motherboard/CPU fan or any other fan or component of the computer. I've confirmed this by sticking a pen into this particular fan to stop it briefly, the noise stopped along with it and started up again when I released the fan.

-I am not a computer tech myself (obviously), I don't know how to disconnect the fan safely. I can't even trace the fan's wire back to its power source, since all my computer wires are bundled together. I've been told not to disconnect the wire from the fan itself since that could cause problems and that it must be disconnected from its power source first (the motherboard or power supply I presume), if I disconnect it at all. As I've said though, I'm unable to trace the fan's wire back to its power source.

-I have used compressed air to blow the dust out of my computer, it did have a large accumulation of dust everywhere, however, this has not made the offending fan any quieter.

-For various reasons, I cannot turn off this computer and have no other computer that can take its place temporarily, so I must leave the computer on and find a way to deal with the noisy fan.

-I really don't want to pay some guy $100 to come out here and unhook a wire or two. I'm not able to take my computer anywhere and have no local friends/family who could help. The only way I could get assistance is to have a tech come out to my place, which isn't cheap. I don't know any techs in the area so I'd be having to use a complete stranger which is unlikely to give me any breaks on the price or do me any favors.

My Question:

Since this is not the motherboard fan or another hugely important fan, can I stick something like a piece of cardboard into it to stop it from running for an extended period of time without causing any damages or electrical surges to any other parts in my computer? My long distance friend who knows more about computers than me has said that doing this could cause unforeseen consequences and he isn't sure its a good idea.

I don't really care about the fan itself burning out at this point, since it sounds like its dying anyway. I just want the noise to stop.

I guess I'm just wondering if whatever problems a blocked fan could potentially cause would be severe enough to make paying someone a bunch of money just to disconnect the fan the more favorable option at this point.

Would really appreciate some help, thank you!

  1. yeah, I would advise against just sticking something into the fan as well. in theory all that'll do is eventually wear-out/burn down the fan motor. but what'll occur when that happens is beyond me.

    see if you can find a local computer shop or find a friend who's a bit knowledgeable to remove that fan properly
  2. Why not use speedfan to turn off the fan or atleast slow it way down

    Edit: I have speedfan downloaded but I'm not sure how to use it really.

  5. speedfan is a piece of software, you can download it here:

    given that you said you know little about tech, I would call up your long distance friend while you do this. you don't want to turn off the wrong fan
