The FlowFX noise.

[Basic]

One interesting experiment for modders.
As you can see, the duct is clearly separated from the rest of the card. The only thermal interfaces for the duct is the in/outlet on the backside, and the Cu bridge to the GPU. So it should be rather easy to add some soundproofing material to it without disturbing thermal transfers. Here in Sweden you can get cheap soundproofing material that should stand the heat at "Biltema", the one I'm thinking of is classified to be used in engine compartments on cars.

Then add a duct for the air outlet. Just one bend or two with the same soft soundproofing material. You'll reduce the sound going out at the back, and as an extra bonus you'll separate the in and out flow.

Well, you'd have to be careful not to coat any circuitry, but sure, I suppose it could be done. However, the external ducting would probably be far more effective, even if it is ugly as sin, as most of the noise produced inside the case should be muffled out by the case itself anyway.

But I'm not really sure you need a soundproofing material that is classified for the engine compartment in a car

Well done for pointing that out. Psychoacoustically spekaing, 85dB is about twice as loud as 77dB.

Actually, 85dB is roughly 7 times louder than 77dB.

58dB is over twice as loud as 54dB, and 77dB is precisely 20 times as loud as 64dB.

There isn't an insignificant difference here folks... that thing is just damn noisy.

Actually, 85dB is roughly 7 times louder than 77dB.

But you can't think in those terms. The human audio system, just like our visual system, works (roughly) on a logarithmic scale, so 85dB does not sound roughly 7 times louder. It only sounds somewhat louder (depending on background noise). The dB system is a logarithmic system for a reason, not just for kicks.

Yes, I should have stated "intensity" or "power" instead of "loudness." Apparent loudness doubles roughly every ten decibels, and my hastiness resulted in that mistake on my part.

MuFu was correct in his statement. I should have known better!

Our hearing isn't "rougly" on a logarithmic scale though, or a doubling of apparent loudness would correspond to a doubling of decibel level, and that certainly isn't the case. It is somewhere between linear and logarithmic.

I listned to the mp3 on thg (only thing useful in that review ). Reminded me of delta 60mm fan that I used to have running on the full 12v (I had it at 5v most of the time). It's got to be bad when it starts to drown out the beep :|

I just listened to the mp3's again and remembered reading this comment... the fan couldn't have drowned out a beep in the FX sound clip. Since the fan only kicks into high speed when a 3D program is started, they must have already had the computer booted into Windows when they recorded it. They just put the beep in the 9700 clip as a reference point for volume comparison during playback.

Lets not get technical guys/gals..it was loud..no need for 'spin'.

 

[Simon F]

What's generating more noise?

This thread or the FX?

As long as it keeps the "hahaha loud fan" jokes out of the rest of the discussions, I'm all for this thread.

Good point.

BTW, what will this do to the meaning of the derogatory term "fan boy"?

 

[Riptides]

all i want to know is..

will the GFFX come with a bag attachment for the outflow
and a good hose for the intake with the hardwood floor attachment and the crevice cleaner ?

That way my woman can vaccuum while i am gaming.

 

[Ante P]

just put it on a stick and plug it in, then go get rid of those pesky leaves on the driveway

Found another clip of the NV30 noise.

Pretty ridiculous, I think you'll agree.

At Tom's, they said the fan revs up at boot then reduces to 2d speeds. I hear a beep about 12 seconds into the clip, right after the fan slows down.

Well it was actually a home-made jet engine, but close enough...

Ahh...that explains the lack of the characteristic FX "whine" then.

 

[Nappe1]

ahh.. back from home...

the reason why I started this thread with so extreme comment was that during last few weeks I have noticed that only extreme comments gets full attention. So, all that I did was read few Chalnoth's and Hellbinder's comments creating massive amount of posts and used same formula for mine and it really worked.

Maybe I'll continue on this line on the future too... though, it's not the nicest way, but at least most efficient to get good fight/conversation to up and running.

I was doing a bit of mixing in my brain

My point was the whine reminded me of a 60mm delta at 12v. Comparing the noise of the fan to the noise of the beep shows it to be an unacceptable noise level for me.

Guys, sorry to pull my audiophile knowledge out here, but the human ear percieves every 3 db as twice as loud..... at least those of us that are refugees from the 60's have no hearing left for the GFFX to irritate...... well maybe.... hehe, we still hear fine at 1KHz...... it's just the top end that's gone........
