    Odd noise coming from the horizontally placed fans

    Houston, we have a problem.
    I have quite a few fans in my second rig, and only two of them are horizontal.
    At first the one at the top of the case started making a weird sound sometimes. Hard to describe it. Reminds me of the pump noise a bit. I could stop it, then let it run again, and it would be silent. I got tired of this and removed it.
    Now the same started happening with the second fan. The problem is that this second horizontally placed fan is on my graphics card, and I cannot really replace it.
    Is there any idea what I can do to fix it?
    Any help would be much appreciated. Thanks!

    The first fan that went bad was similar to the one I linked above.
    The GPU fan is this one:

    Any more ideas what to do with the GPU heatsink fan from the picture above?
    What can be causing the noise anyway? It doesn't have the noise all the time... Can suddenly start and stop... And it's constantly spinning for sure.

    Sounds like its starting to give up. I'd buy one of those pci-slot fans, pull out the fan and glue it in place on the gfx card, should work

    This. I had that same problem awhile ago when i had an aftermarket cooler on my gpu. It will make sound when it gets off balance and starts spinning weird and one day it die out soon afterwards.

    Meh, thought so.
    It's kind of funny that horizontally placed fans are dying first, though. Interesting observation.
    Ah well, going to look for a replacement!
    Thanks everyone for your feedback! Even though we couldn't find a fix, but it is still very much appreciated.

    sleeved bearing fans ........ assumed
    they normally meant to be place on vertical ... if placed on horizontal, the lubricant doesn't retained correctly and thus causes extra noises ... sometimes, even burning smell may occur ... not to mention it shortens the lifetime of the fan

    get ball bearing fans if you wish to place the fan horizontally
