As for the size of the cooler, it doesn't make sense for it to be a 1x120. The article guesses what it is from the picture. A 120mm rad is capable of dissipating what, 100W with a fan that won't be silent? Think about this for a second - CPUs with TDPs below 100W are using 2x120 radiators. What does that say for a GPU that will be in excess of 100W?

Why do fanboys look at leaks and then *scream* at the top of their lungs as if the leak is the gospel truth?

You don't understand basic water cooling principles. Read up on it before you continue bashing a superior solution.

Do we have to remind you that the 295x2's 120mm rad is dealing efortlessly with 500w worth of heat, at lower GPU temperatures and similar noise (including the VRM fan) than *any* sane reference card (be it an AMD or an nV)?





And we all know the X (250-300w, similar power envelope as Hawaii) is gimped by nV's blower, it has almost no headroom at all. It throttles like crazy at nV's preferred temperature and fan speed settings depending on the load. If you decide to shoot for stock 290x noise levels then it's a fine cooler for such a GPU... going forward they're gonna have to do something about it.



Let's assume the 390x's absolute power ceiling is 300w which is 200w below the 295x2. The VRMs are included in that budget. If the block covers the VRMs, then we're looking at the best cooled reference card in history. Keeping the same 70-75°C target, that 50dB noise reading of the 295x2 then goes down because the rad is dissipating 200w less in our hypothetical 390x, less fan speed needed. Whisper quiet.

No matter how you spin it, the CLC *is* the better solution. On top of that it's been shown that such a load (290x) today can be air cooled quietly and efficiently (Sapphire's Tri-X editions and the like, which have load temps at around 70°C, just like the 295x2)


If you don't have a free 120mm fan hole where to mount the CLC version then you can always buy one of the air cooled versions which will do just as fine. I mean, in the leaked slides the watercooled edition is explicitly mentioned, it implies there will be other options. How it's cooled is a non issue, not anymore. It's all shaping up to be a great lesson for AMD on not skimping on the cooling, quite a needed one.

The 295x2 only pulled off it's solution with both a fan on the card itself, a heatsink plate covering the card on the front and then a loud fan on the rad as well. And even so, it didn't pull great temps.

Well, aside from any temperature complaints, what you just described is the entire design scheme of hybrid cooling.

The idea that there ISN'T a fan on a card cooled with a CLC/AIO is rather alien, because the CLC is always dedicated to the GPU/CPU, it doesn't cover anything else. No matter what you do, on high performance cards, those other components on the card need cooling too.

Look at the Kraken G10, it has a fan. It does nothing about adding heatsinks or anything, it simply creates passive airflow.
Corsair HG10 is not nearly as universal, but aims to take the blower fan from reference cards and incorporate it into its cooler assembly for the same purpose, but it runs at a slower speed because it doesn't have to work as hard.

Having a fan on the video card is hardly an issue, these solutions don't require high speed fans, so long as the card still has some attention paid to passive cooling. Thus, a heatsink baseplate; my 290X Lightnings have them, and one of them has the G10 on it, so the VRMs and everything stay cool.


Don't forget that the 295X2 is a monster of a heat producer. It has two pumps for two GPUs, and a single regular-thickness 120mm radiator, and I believe stock has a single fan. That's hardly enough, so that fan has to work harder than it should, but it produces less noise than a capable air cooled solution.

Such a regular-thickness 120mm radiator is exactly what I have attached to my 290X Lightning, though I have a dual-fan setup. Overclocked to 1200 core/1500mem, with the fans hardly crossing 50% on the CLC, the temps are always 10ºC cooler, or more, than the same-specced stock card I have below that one, which can reach into the mid 70s. I don't hear the CLC cooler, and it's hovering around 60-65ºC. (this wasn't true with stock Corsair fans, those fans sucked. EK Vardar F4-120s are the bomb, a spiritual successor to the famed Gentle Typhoons that can be hard to find (around 1800rpm or so is a popular GT, the F4-120s are around 2100rpm max IIRC).

Anyone remember PowerColor's Devil 13? It did a decent job of cooling the 295x2 on air. Mind you that the card was really heavy, thick, and ran pretty warm.

CLC really makes sense; but seeing how well some aftermarket coolers can dissapate heat makes me wonder of how far air cooling can really go.

just stay with nv? I don't understand you. you seem to hate water cooling and is 100% sure there will be no AIB air cooled versions for the 390x.

stay with nv you are 100% sure right? stay with nv. there is no need for you to join the discussion, at all. stay with nv, cause, you will never change your mind no matter what it seems.

I for one am extremely looking forward to it. I can't wait to see the temps n noise graphs. I am 90% sure the wce version is what I will get

Going forward, as long as we're on the same 250-300w upper limit, air cooling has a place for cool and quiet... at least open air designs that rely on case airflow to work. Blowers on the other hand, I don't think so.

Powercolor's 295x2 has shown that it gets a bit difficult for air cooling to dissipate that much heat under the constraints of a GPU cooler's dimensions. I'm pretty sure that if we could somehow slap two noctuas NH-D15 on both GPUs it'd be just fine if you can sacrifice all the expansion slots :biggrin:

They claim its 100% confirmed official blah blah. Its possible to cool the vrms and other hot components with water, the vents being for the rest. This design investment could account for the rumored $700.

If AMD is really going to charge $700 for this, it will have to beat the Titan X and win the performance crown outright. The rumored 20% over GTX 980 won't cut it.

That's only one rumor. It's not THE rumor like you say. Also, do you have an AMD source for the price since you are attributing that price to what AMD is going to charge?

No, I don't. That's why I spoke in the conditional: if AMD is going to charge $700 for it (as Azix had apparently heard) then it's going to have to beat Titan X in order to sell well. Now, if it costs $499 (and to be clear, that figure is 100% speculative on my part), then it could beat GTX 980 by 20%, fall short of Titan X, and still sell well as long as power consumption wasn't totally crazy (i.e. <=250W TDP).

Dude, the 295X2 also had x2 GPUs! This is x1.

You can't just say "It has to beat Titan X or its teh failz". It's going to come down to price, performance, acoustics, power draw, etc. Just like always.

Considering Hawaii beat GK110 and it what, a 438mm2 vs a 551mm2 chip..

Now it should be a ~550mm2 Fiji XT vs ~600mm2 GM200 battle.

Fiji XT should beat Titan X given its close parity in die size and with a major memory advantage. If it can't, it's a failure.

Now lets be careful. While I agree the X's cooling is subpar the chip does have a 1000 mhz base and 1075 mhz boost. Anything over 1000 mhz is not throttling.

That said a good aircooler can handle 300W and Fiji should have no trouble under air.

Not necessarily true. Regardless of the 390X's performance you still need at least two for 4K. And Nvidia is on the ball usually with SLI profiles, game-day patches. Crossfire still doesn't have support in a lot of titles even a year+ after release. Anyone looking for 144Hz/1440P or 4K might have to consider that when factoring a dual card purchase.

What does it matter if it's faster than a Titan X or not? It's not going to have a four digit Titan X price tag so why does it have to be faster? If the 390X can provide the majority of Titan X performance at a competitive price, then it's not a failure.

I honestly don't understand some people's "logic".

Hawaii didnt beat GK110
GK 110 fastest GPU was 780TI/Titan black and 290x beat only cut-down GK110.

alot? you have a source for that?

I went ahead and looked at some of the featured mid tower cases on newegg. Most have a single 120 or 200mm fan rear mounted. Until you go full tower, you don't see 2x120 become common. Mid towers just won't have the space.

As for the size of the cooler, it doesn't make sense for it to be a 1x120. The article guesses what it is from the picture. A 120mm rad is capable of dissipating what, 100W with a fan that won't be silent? Think about this for a second - CPUs with TDPs below 100W are using 2x120 radiators. What does that say for a GPU that will be in excess of 100W?

Why do fanboys look at leaks and then *scream* at the top of their lungs as if the leak is the gospel truth?

Then how do you explain the 295X2?



Unless you're trying to imply that this will use more power than the 295X2? You're vastly underestimating the effectiveness of GPU watercooling.

...

I don't know if you're trolling or not, come on. Just... COME ON! You need to check yourself before you start talking about other people being fanboys, my friend. Looks like I have a list to add to...

What about driver quality and release cadence? Don't forget multi GPU profile updates which AMD drags its feet on. They have to catch NVIDIA on all fronts, not just the hardware.

Well, I guess we'll have to wait and see. I haven't had any AMD single card driver issues in years, so I'm optimistic. I've never tried Crossfire, so I can't comment about multi-GPU.

So an 8GB HBM card that's 20% faster will have to sell for less? That's only what the people who wouldn't buy AMD anyway think. They only want the price of nVidia to come down which is how they price AMD cards.
