    Default Corsair CX450M - Grating/Grinding Sound from Fan

    Hello

    I recently purchase a CX450M. When the fans spins, there is a noise that I can best describe as a grating or a grinding coming from the fan. The PSU was orientated with the fan at the bottom so that air is being sucked up into the PSU. I reversed the orientation so that the fan is at the top sucking air down into the PSU and now the sound is louder.

    The sound is relatively soft with the fan noise from my HIS 6670 being louder than the PSU fan. However, if I remove the 6670 I can hear the grinding if I listen for it, even when the computer's side panels are on.

    Please note that I haven't opened up the PSU to look at anything more closely since I don't want to void my warranty.

    Is the PSU fan faulty? Is something misaligned that I can fix or oil? Do I need to RMA? (I am in South Africa.)

    Thank you
    GDI Lord

    Probably bearing noise, if you don't like it RMA the PSU.

    Similar thing happened to my Vengeance PSU.

    Here is the video that I recorded: https://www.youtube.com/watch?v=Izcc0UbHkjI

    See if you can push down on the hub of the fan. You'll need to remove the grill to do this, but that won't break the warranty void sticker.

    Push down on the hub firmly in the middle to help "seat" the bearing. I hope that would fix the problem. It usually does for me.

    Thanks Jonny, but that did nothing.

    RMA it.

    I can try to help the process if you want to go ahead and make your ticket at corsair.force.com and then PM me the ticket number.

    Thank you Jonny.

    How long does the RMA process typically take, bearing in mind that I need this PC for work, I am in South Africa, and that I bought it from a (very reputable) online store? If the questions sound silly it's because I've never RMA'd anything before.

    It might just be a fan blade hitting the grill. Make sure all fan screws are snug, then back them all off 1 turn to see if it goes away. If not, you might need to RMA.
