close look of NV40

[Bouncing Zabaglione Bros.]

If you're going to produce that much heat and need a monster cooler that uses a second slot, venting it out the back of the case would have made a lot more sense.

Maybe the benefits of keeping the sound inside outweight the benefits of venting the air out this time, might at least produce fewer dustbuster jokes.

The VGA silence shows it can be done very quietly, and actually *lowers* the temperature in the case, allowing the rest of the case to be quieter. The cooler keeps the GPU cool, and additionally acts as something that extracts heat from the case, not adds to it.

The additional heat put directly into the case by the NV40 will make a lot of systems unstable - maybe even the GPU itself if it can't get enough cool air from the inside of the case. This instability will be blamed on the NV40 even though it's only the indirect cause.

The VGA silencer shows it can be done very quietly.

The VGA silencer has alot less heat to remove than the 5800 or 6800 pump out.

That's exactly why improvements such as using copper, better base finish, better fin structure, etc. have been suggested.

Doesn't anybody read here or look at temps??? Do a search on which whether ATI or Nvidia Ocs better. Nvidia by far. They dont NEED to put this big of a fan on. Nvidias temps are ALWAYS cooler than ATIs. Check out Anandtechs 20 card round up ATI's cards run (dont quote me) 80C nvidias are around 40-50C. They COULD put on a cooling solution like ATI's but then there wouldn't be as high of OCs and there would be a lot more heat.

It manages to drop my case temp by 10 degree. Early reports are than NV40 adds to case temp by 10 degrees (before system shutdown).

I'm obviously not suggesting that you could just put a VGA silencer on an NV40, but the idea of having the fan to the right of the GPU and then a covered fin that blows the air though the second slot position would make a lot of sense. You could probably get away with less noise if Nvidia used a larger fan or a centrifugal fan as they have now.

Instead what they have is a hot part that heats up the inside of your case, a (possibly loud) centrifugal fan that takes the hot air and then uses it to inefficiently cool the GPU, and then puts the heated air into your case where it helps heat up all the components - including the GPU you are trying to cool.

That just about redlined my Troll-O-Meter. :?

EDIT : you are probably referring to this - http://www.anandtech.com/video/showdoc.html?i=1955&p=18 Note the difference between IDLE and LOAD temperatures... ATi cards don't have clock throttling, hence the high temps in IDLE. On the other hand, look at how fast the temps are growing on nVidia cards when under stress.

You're half right and half wrong. In idle the HIGHEND ATi models are hotter, but under fullload the HIGHEND nVidia models are a good deal hotter.

 

[gamingphreek]

Yes, that is what i was reffering to. I overlooked the throtteling however... but also notice that (i think) those are OCed to the highest. Nvidias solutions OC much higher than the radeons and are a little hotter.

 

[Mark]

I notice that all 8 memory modules are on one side of the PCB...

 

[I.S.T.]

I would say more than a little. The hottest nVidia based card is 20 degrees Celceus hotter than the hottest ATi based card. Also, in the case of the nVidia's GF-FX line, overclocking them doesn't mean all that much, unless I am mistaken. The performence is still lower in almost all regards than the 9700 and up line.

I think I beat you to it, anaqer. Edit: Was replying to gamingphreek.

 

[nobie]

I dunno about the high end cards, but overclocking a 5600 gives pretty good results.

 

[Joe DeFuria]

Yeah, that's to be expected though for a GDDR-3 board that should be available in a 512 MByte configuration. We should see the same thing on Radeon X800 Pro and XT boards.

All of the GDDR-3 chips, AFAIK, are available in 256 Mbit densities, so 8 chips will get you 256 MBytes. Throw another a chips on the back (sharing data paths with the chips on the front) to get your 512 MByte board on the same 245 bit bus.

Agreed 100%. I just seriously doubt, with the quoted NV40 heat figures, that it could be done quietly in a 2-slot design - quiet being VGA Silencer quiet, not regular stock heatsink whine quiet. Even with a big slab of lapped copper, ultra fine fins, and so on - the best heatsink in the world won't help you if you can't get the heat out of it.

I'm eagerly awaiting the new VGA Silencer as the original heatsink is a pretty useless (but also cheap) design. I hear HIS/Hightech will be slapping it on their X800 line and it will have integrated memory cooling, so it could be a winner.

More and more people get sound conscious every day.

I will not buy any VGA which can't be made almost totally silent. I dont want extra fans in my case besides the two 120 mm low rpm ones.
Yes, you may say watercooling solves Nvidia's problem.
But I'll go for R420 even it is considerably slower than NV40, IF it will have more decent heat dissipation. (Well and if it performs 20% better as the 9800XT - somehow I don't buy that marketing BS that The 6800 Ultra is up to 8x faster than previous generation)

 

[anaqer]

That you did. It's kinda hard to write fast AND avoid mixing in Rob Zombie lyrics booming in me ears.

 

[gamingphreek]

You have it back ward Nvidia benefits MUCH more than ATI in overclocking. yes the temps are higher but what does that matter if it is overclocked so much higher.
As to something about Nvidia cards getting beaten by all the ATI cards...what the hell have you been reading. yes ATI is overall a little bit better but they are neck and neck. 9700 PRO beating nvidias highed... still dont know where you got all that from 9700 gets beaten by 5900XT. It is very close right now and ATI seems to be doing a bit better off than Nvidia but saying that the 9700 PRO kills thats way over the top (not that its still not a fast card)

Learn the world of marketing, they said previous cards not specifically the preceeding NV3X generation. I am sure it is 8 times faster than the GeForce 2.

 

[I.S.T.]

Um, several things.

1. 5900XT is not a high end board. It's a middle end one.

2. I've been reading several sites, including this one.

3. I never said or implied anything about ATi gaining mor performence via overclocking.

4. I said 9700 AND UP. That means everything from it to the 9800 XT. The 9800 SE isn't being counted as it's a middle end board.

5. Please read what I say, not what you think I say.

Edit: was replying to gamingphreek. Edit2: You do realize that the 5900XT is nothing more than a downclocked normal 5900, right? They used to call them 5900 SEs. Edit3: Here's some links that prove that the 9700 PRO is better than the 5900 XT. http://www.beyond3d.com/reviews/sapphire/9700proue/

The XT isn't in this review.

That one has the XT in it. Let's look at some benchmarks that are in both reviews.

Where do I start?

 

[gamingphreek]

Ok
I need to clarify somethings.
1. 5900XT is not an underclocked 5900 or 5950.. that is just a plain 5900... the SE and XT use slower 2.8 ns memory so they cannot achieve as high a clockspeed. and the XT goes even further by lowering the core clock by 10 mhz.
2. Comparing cards across reviews is not "right" you have to compare them in the EXACT same environment with latest drivers for all (i didn't look at the system and drivers they test them on so correct me if im wrong )
3. 5900XT is a highend video card... it may have a price like a middle end but it is a highend the performance results can show that
4. ATI and Nvidia are pretty much neck and neck... ATI is probably a better choice right now as it wins big in a few more than Nvidia does.
5. I wasn't saying what i thnk you said :? (lol) you said it

Also, in the case of the nVidia's GF-FX line, overclocking them doesn't mean all that much, unless I am mistaken

No offense meant to anyone... just explainin myself
