case fan replacement causes case to vibrate

[daggs1]

Greetings,

I have a vsk2000-u3 build. the provided case fan was to noisy so I've replaced it with a Noctua NF-A9x14, I've connected it using the rubber thingies and used the LNA cable.
now the noise is lower but the case vibrates when I touch it.
is it a normal behavior? if so, can it cause any damage to the hdds inside?

Thanks,

Dagg.

If your CPU cooler is installed properly (and if the fan isn't defective), it should not vibrate (especially with the anti-vibration pads on it).

I own around 15 different Noctua fans, and none of mine do that whether they are installed on the case or a heatsink. Maybe try installing it using the "rubber screws" instead of metal screws, and see if that helps with the vibrations.

I didn't touched the cpu cooler, the cpu temp is around the 38C~40C.
maybe I didn't inserted the anti-vibration pads good enough? it was really hard todo so.
how can I verify if the fan is defective?

You can try remounting it, and making 100% sure you did it correctly (or use the silicone mounts instead of the metal screws like I mentioned in my first response). This will further isolate any vibrations to your case.

If you are confident you did it correctly, it's likely the fan is defective. However, generally when a fan is defective, it will be noisy and not silent.

as said, I used the silicon mounts, I didn't used the metal screws, will try remounting it again, thanks.

If you used those, make sure you installed them correctly by looking at the pictures in the manual. Otherwise, you can try using the metal screws and see if that helps the vibrations. It all comes down to the thickness of the metal in your case. If the metal is thin where the fan goes, it could be the reason why. You can also always go in your BIOS and reduce the fan speed.

unfortunately, the manual's drawing is wrong, it doesn't displays the fan I have.

the fan that came with the case was connected using silicon mounts, what are the chances I can use that ones instead of the supplied ones?

the fan speed was 900 rpm in bios.

Why not use the ones that came with your Noctua fan? I don't know if the ones that came with your case are good quality or junk?

I don't mean to sound rude, but installing a Noctua fan with the included accessories, and following their detailed instructions is a pretty straightforward process, and it seems you are overthinking the process.

well I used them and the case vibrates, granted there is a good chance I missplaced them somehow but still I want to try to pinpoint the main issue, assuming I can use the ones which came with the case and the doesn't vibrates, then either something wrong with the mounts (less probably) or I didn't connected them well (most probably).

searching the case on line, I saw multiple clams that the fan was noisy and we replaced, I thought I test it myself and indeed it is noisy, at 3 meters away you can hear a humming sound

here is an inside look into the case:

as you can see the fan is hidden below the tool less mounts, I don't know how to disconnect it and the manual doesn't say how, even without the mb it is hard to fit my fingers there and pull the silicon pins, I'll try tomorrow after I take everything out of the case, maybe it will work.

Here's a post where a person details their build with the case you selected, and it looks like there should be plenty of room to get to that fan. If not, that whole assembly can be removed from the case:

Greetings,
I know that entry, I've followed it but it doesn't says how to remove it, anyway, I was able to remove that bay using a flat screwdriver (the case is rather flexible), I've placed the fans again (yanked the hell out of theses mounts without tearing them), the vibration is considerably down, it still vibrates a bit bot no that much, I think this issue is solved.

thanks for all the help.
