Noise Dampening Foam

[arch_linuxos]

My radiator fans are loud. They look cool and work well, but they're loud, and I can't make them not go 100%. Sigh.

 

This new case improves upon the noise of my old one because of the closed top, but it's definitely still audible at idle.

 

So, does anyone know of good noise dampening foam or inserts of some kind to put in my case? Preferable kind of thin so they can fit in the top section without restricting airflow too much. Case is Enthoo Evolv ATX, other specs in signature if you need.

what about in-line resistors for the fans? like noctua includes.
and your Asus motherboard should allow you control all your fans....?

do you have a lot of fan filters installed? if so removing or replacing them might be a better option

Acoustic foam will literally do nothing if you have loud fans.

Instead of spending money on foam, spend money on new fans and either connect them to your motherboard (to control them) or sue a fan controller.

I want them to be able to go full speed if they need to is the thing. And yes, it does :). Just not the ones on H110i GTX.

What do you mean? Like dust filters? If so, yes, on every intake. But not exhausts. Would rather not remove them over intakes.

Are you sure? I've heard it dampens noise... The issue is not the fans vibrating or anything, it's the noise of the bearings. And foam is way cheaper than two good new fans friend ;). 

 

I've tried connecting these to my motherboard, but it always gives CPU Fan Speed Error (I disable that, of course). Then, though, I get super long boot times for some reason. So some way to lower the noise level seems like the best option.

It is meant to be used in rooms to reduce echo and reflections off walls.

If you put it inside a PC case it will barely make a difference.

 

Having silent fans makes a MUCH bigger difference than foam.

And (real) acoustic foam is $10-40 per square foot which could buy you new fans anyway.

 

If your motherboard doesn't work properly then use a fan controller, those cost less than $30.
