How to fix eerie wind noise from case fan

[element059]

Hi guys,

Weird question but this is bugging me. I've got two Corsair static pressure fans mounted at the bottom of my case and they are producing a really eerie wind noise. From what I've found it's caused by the width of the grills in the case. From experimenting placing the fans under a push configuration or moving the fans 2cm away from the grill fixes the problem. However, none of these are real solutions as they can't be mounted in this way.

Would a different fan type such as a airflow fan or maglev fan solve this issue?

I also have one of these fans vertically mounted at the rear of the case in a push configuration and it doesn't have the same issue, so seems to be the placement and grill type that's doing it.

Thanks

If there's space for the fans 2cm away then they can be mounted like that. I've done it before by taking another fan of the same size and cutting out the actual fan, leaving only the frame. The empty frame can then be used as a spacer for mounting the other fan.

That's a good idea thanks ill try that
