Re: Are 2 fans noisier than 1 blowing the same CFM?

I know this is an old topic but i thought i'd throw in my piece. The +3dB doubling only applies when you have coherent wavefronts. In the case of two subwoofers next to one another, it is possibly to achieve because the frequencies are low, and the wavefronts combine to produce a higher pressure wav...

perhaps i asked too many questions in too little space and became unclear.
startup/dvd playback noise
This is the only noise i am concerned about. I presume cd playback would be as quiet as dvd playback.

Upgrading my case and DVD

i must say, i speak to two people regulalrly who like to have loud fans so "they can hear it's working"

It also means cd/dvd burning doesnt irritate them, as it cannot compete with the cooling fan noise.


Personally i think they're insane.

Excellent, looks like this is the card for me.

i'll be using phono outs most likely. I also have a stereo system, so game's shouldnt be an issue should they?

Sure they'll load the system down less than my nf7s crappy onboard sound.

I'll be baggin this

Perhaps you should mod a couple of test points for the fans voltage - if it reaches 12V regularly then the fan probably isnt providing enough cooling and you should switch it back?

if you intend to overclock, you should get one with a higher rating, at least a 350W model, though that may still hold you back.

Inspiring work as ever bluefront - I've been thinking about the "emergency" fans idea for a while, glad to know it wasnt foolish.

The other thing that caught my eye was the foam or whatever round the i/o panel - is that to stop noise dust or both?

Yes it's pretty easy.

All you need to do is hook up a 12V relay that'll close two pins on the 20 pin atx connector that isn't plugged into a motherboard.
I can't remember which pins but google knows.

I'm trying to think of a good way to do some real objective testing - it would be lovely to come up with a reuseable, thermally invisible micro-coolpak to replace thermal compounds.

i believe it stands for native command queuing. Something to do with holding commands in a memory and executing them in an order that will be most efficient.
