Sound dampening acoustic foam?

post #1 of 5
Thread Starter 
My current system (in my sig and build log) is pretty much silent at the moment. It's at the point that during the day, with ambient noise, you gotta really listen to pick out the any sound that comes from it.

Early in the morning and late at night though... the noise is there and will typically bother me. So I just want to try to minimize the noise even further.

The point of this thread... anyone ever used something like this acoustic foam for dampening? I'm guessing I could put a piece right between the inside of the case and side panel. Then also by the bay areas where I have my reservoir/pump and in other areas I could cut out little blocks to fit in.

Just wondering if anyone has tried it and seen a different. I'm guessing it should... but would love to hear first hand what some of you think. thumb.gif

You could get some low db fans, and some rubber mounts for the fans, but it highly depends on your case, especially if you have a lot of grilling on the case/plastic mesh front pieces, etc. For better dampening, I wouldn't spray foam in the case, but use something like dynamat, which is use for car audio dampening. There are cheaper alternatives to dynamat which are better though, so I would just do some research on that.

It is 100x easier to reduce noise by not producing noise rather than trying to absorb noise. It also kind of depends on the nature of the noise you hear as to whether it can be absorbed, dampened or otherwise attenuated.

I would start with trying to figure out what is making the most noise in the system, and see if there was a way to reduce that specific noise output first.

^ What he said.

Low db fans and an SSD can do wonders.

Yea... I appreciate the advice but I'm way beyond that. Like I said... the PC is nearly dead silent as it is. I wanted to get rid of the slight hum that the water pump makes while it is on....

SO! I bought the foam that I linked to in the first post. Then I set it up all around the areas I could and now... I can only hear the PC if I put my ear within 2-3 inches of it. Otherwise... there's no difference in sound while it's on or off. biggrin.gif

Extremely happy!
