GeForceFX 7db cooler

Does anyone really think that a company like Gainward, Leadtek, MSI, or PNY would be happy to sell a card with a 70dB FlowFX on it?

We know ABIT is capable of intelligent cooling designs. The others have the capability as well, it's just never been flexed.

I'm quite certain that the designs being sold in volume with be much different than FlowFX.

This is pretty much what nVidia has said all along. Many people on these forums acknowleged it, most can't see past their nose or haven't followed this industry long enough.

That being said, I'm also pretty sure that if the FlowFX got a warm welcome from the community many AIB's would probably consider it for their Ultra parts.

But for mainstream, it's too impractical, and by the looks of it, too expensive as well.

On the contrary hexus.net has pictures of the Abit Siluro Geforce FX and it uses the same noisy cooling as the reference design GeForce FX.
I'm betting my Radeon 9700 Pro that it will be a heatpipe design. Peltiers will not work without water cooling, water cooling is out of the question, vapo chill etc is just an impossibility. 7 db means nothing, they might as well say noiseless.

I would like to see some pictures of this 7dB FX.... If it´s something possible, the reference card is a piece of sh¡t compared to this one...

I'd fully support ANY card with quiet cooling! If this thing is quiet and reliable I'm 100% for it! Hope they use the same quiet tech on all thier other cards too!

Hope they also give you back your PCI slot! (in the case of the NV30.)

that is doubtful as they still have to dissipate as much heat, but they just arent using the same cooler, the may be using a massive hs w/ a low db fan and it will have to exhaust somewhere and most enthuasists dont want that much heat in their case

A fanless heat removal system for a GF4 was in the news a couple months ago. Basically 2 massive aluminum plates as large as the entire card - and on both sides of the card, connected to each other - with cast-in cooling fins over the entire surface = massive heat sink + massive convection cooling area - with flow driven only by thermal density gradients.

Well what really doesn't make sence is that anything under 24 db isn't really worth going for imo. 7 db sounds like a joke to me since anything else inside the pc will be louder than that (any other fans or moving parts).

Depends what freqency the sound is at, in a specific wavelength it is possible to hear 0db. But for all intensive purposes anything less than 20db is inaudible.

IMO I think they forgot to put a 5 in front of that "7db" I don't care how high quality of fan you get the only way I could see a GFFX being halfway quiet is to use a TMD fan and even then your talking 20-30db.

Honestly though I want to see some engineer get like totally crazy and put the card backwards. Put the GPU on the opposite side of the PCB. Then you could put a very large heatsync without too much issues as you are not stealing any PCI slots. Of course that is putting more heat near you CPU but when your putting off the kind of heat the GFFX is you have to do something extreme.

I am moving to a entirely ATI graphics cards on all my machines (Rage Mobility (heh laptop), AIW VE (Theater 200 chip on it!!) in PVR, Radeon 9500 with 9700 hack on primary desktop) I know they are still the underdog but I am very happy with their products, and their driver support is getting there.

Practically? 7db is freaking silent. I don't think I hear well enough any more to be able to hear that from close up.

Hope they also give you back your PCI slot!

Or do you lose both PCI 1 and now...PCI 2? :Q

if they lower the sound of the fan doesn't this have a direct relationship to the amount of heat left in the case?

i guess waiting for the reviews are necessary to see if this solution makes a viable recourse for gainward.

He means that if it is not using the whole air duct contraption to expell heat directly out the back where will the heat go?

I have a 50% overclocked Celeron (and overvolted) with a miniscule 23.5 cfm fan. Mind you the heatsink is MASSIVE, and I've got quite a few case fans. I just ripped one of them out though because it was too loud. I'm thinking of replacing the power supply too with a quieter one.

How much heat is the Geforce FX going to put out anyway? 75 W? I think my system would handle that in its current state (with 2 case fans an a power supply fan), but my CPU probably puts out half that. I dunno what an Athlon XP with Geforce FX would be like in my case.

However, if you're concerned about the case temp and noise, I suppose you could just rip out ALL your case fans and just take the cover off. Works well, although I'd never do it.

Why don't they do that? Then you could have an almost CPU style cooling system on it surely?

With 7db fans, people will complain more about the noise of their hard drives!

I'm sure this comes down to how gainward measures the card.

Even a Delta 6000rpm is 7dB loud somewhere. They never specified dBA,dBC, linear, distance, etc. Basically, 7dB is a meaningless number since it's a ratio and we don't know what it's a ratio to.

This is very true. Giving the intensity reading is meaningless without distance or frequency data. For an extreme example, a jet engine can be as loud as 160dB @ 1m, 1000Hz. Now measure this same sound at 10,000m or 1MHz, and I doubt you'll measure more than 7dB. Just saying a sound is 7dB does not specify if it was measured at 1ft, 10ft, or 1000ft, nor does it specify if the measurement was even taken in the audible frequency range.

The only way I can envision 7dB in the audible frequency range and at a reasonable distance is by going fanless. To do this requires the use of an exotic heatsink. This may be a problem as the heat must be dissipated by free convection inside the case. Those 75watts of generated heat must go somewhere. The most likely result is a temperature rise inside the case with a resulting rise in CPU temp.

That being said, I can't think of a cooling fan used for computing devices (case fan, vid card, processor, hard drive, etc) that only throws off 7db.

By using

these maybe?

Is that technology ready yet though? And can these only be used in conjunction with other nosier fans or can they be used with a heat pipe?
