Assuming NDA expiration is midnight, midnight where?
Why no talk about X850 yet???

actually it's louder: http://www.hkepc.com/hwdb/r430r480-5.htmgordon said:

FWIW here are some more noise figures ...
Would have helped to know if those noise figures were taken at idle.anaqer said:
The power draw/noise data from hkepc above seems pretty reasonable. The x800xl actually looks a bit better in terms of power draw than I would have guessed. An ATI Silencer, or Zalmans new active VGA cooler, will probably be able to tame the direct noise from the x800xl, although they obviously can't do anything about the contribution to the total power draw. Still, better than expected. Will be interesting to see if ATI cut any performance corners on that part.
I guess I'm going to have to make a trip down to Maplin one of these days and do a bit of shopping...

Make one wonder how your wife managed to get a straight "yes" out of you. Hot tongs?
Anyway, in the interest of helping you with noise evaluations, I hereby offer to send you a Zalman 7700 for your FX-55. Should do the job even at its quietest setting. Just let me know. Someone else can donate an Antec Phantom PSU. Then you're good to go, for all practical purposes, assuming suspended FDB hard drives.
20dB? That's pretty close to silent, or at least ambient room noise, AFAIK. I thought stock X800 HSFs weren't as quiet as VGA Silencer v.3s?anaqer said:
Is there a difference b/w dB and dBA that I'm not taking into account? IIRC, a 3 dB difference is a doubling of noise. The 6800 HSFs are really 3x louder than the X800 HSFs?
The X800XL is the most exciting, IMO, especially since ATI said it could be passively cooled in a BTX system. Passive cooling for a 16-pipe GPU sounds pretty sweet.

Not this time. He's probably just referring to buying a decibel meter from Maplin electronics.
"probably"
Actually, as a fellow Baumann interpreter, I tend to agreen wth this hypothesis, which was why I suggested that a serious effort to quiet his current test-rig might be useful. (Not to mention enjoyable!) His comment in the X850XT PE review that he couldn't hear the graphics card fan over the noise of the CPU fan even running 3D applications kind of implies that unless he quietens the rest of the system, he'll never get any useful data from an SPL meter.
If this is true, and I'm inclined to believe it is, an SPL meter isn't much use. Going all passive cooling is awkward (but possible), but selecting the quietest fan assisted components is OTOH straightforward, cheap, and should yield adequate results to be able to evaluate the contributions of the gfx-card.
I was under the impression that a difference of 6 dB is percieved as "twice as loud".Pete said:
BTW, sorry for the sloppy linking - as max-pain already pointed out, the idle noise levels are labeled "üresjáratban" while the ones under load are labeled "terhelve" (and the rest run at a fixed speed).
There's 4 ranges - 40-70dB, 60-90dB, 80-110dB, 100-130dB
Oh, doh.
