Should you roll back to pre heat-pipes days?



Why would anyone invest $70 into CPU watercooling kit, but refuse to TOLERATE free* watercooling kit on GPU? GPU takes easily twice the amount of power of CPU. It clearly is a first part of PC to be watercooled.

Anyone who has watercooled CPU and bashes GPU watercooling design should be checked by a doctor after being hit in his empty skull with a banhammer.


Dude that last one is signature worthy so awesome

You say are okay with it, but people in here are acting like this is a bad step in the wrong direction and that it should not be used. How can we get improvements if people are not open to new ideas.

There are new ideas, and then there are "better" ideas. Throwing water cooling solution at something to try and solve a problem, isn't really addressing the problem. Too much heat to use a far less expensive cooling solution.
I'm all for new ideas, as long as it is a step in the right direction and I feel that water cooling, isn't one of those directions.

Now if the water cooling isn't really necessary for the GPU and it's just an extra gimmick/feature/coolness factor that the GPU manufacturer uses to differentiate their products, then that is fine. All companies should try to differentiate their products. But if it's "required", that isn't the most ideal thing.

I don't know where you guys get the idea that water cooling is required for R290X class of power use. Even the old Gigabyte Windforce design is capable of dissipating 450W and advertised as such. Anyone who has owned a 780/ti Gigabyte Ghz ed can attest it can handle massive OC with lots of vcore (to the point where 780/ti suck down 400W+ of power!).

I don't think watercooling is a problem. I agree both AMD and Nvidia must focus on power efficiency but performance needs to be the primary goal for flagship desktop GPUs. We are in the era of 4k gaming and 8k is on the horizon. The rate of progression of GPU performance has now slowed down as 28nm has the lifespan of 2 traditional process nodes. By the time the first 16/14nm FINFET GPUs we would be past 4 years on the 28nm node. Process node transitions are getting more and more difficult and costlier. In fact the roadmap beyond 7nm is not yet clear.

Today even two flagship GPUs cannot max out the latest games at 4k.

Thats quite telling. I doubt even two Titan-X or two R9 390X cards can max out the latest and most demanding games of 2015 and 2016 like Witcher 3 and Star Citizen at 4k. If thats for a single monitor imagine how bad it is for multi monitor 4k. Multi GPU scaling beyond 2 GPUs is erratic and most titles do not scale well beyond 2 GPUs. With variable refresh technology like Gysnc or Freesync improving the experience at 40 - 60 fps, the road to 8k is looking promising only if GPU performance can keep up.

Watercooling has lower noise, temps and allows better overclocking as it cools more effectively than air cooling. I don't know why anyone would complain with better acoustics, temps and higher overclocking ability as a result of better heat dissipation. Another advantage with AIO CLC is the ambient temps do not raise so the other components like CPU do not get affected in terms of overclocking. Frankly there are no negatives with AIO CLC as even the most basic ATX cabinets have a 120mm rear fan exhaust which can be used to place the AIO CLC radiator fan.

If they're released with reference AIO units, you can bet your ass it's for the same reasons the FX9590 was. I'll leave it up to you to decide if that's a good thing or not.

well said :thumbsup: the R9 290X Vapor-X was designed to handle well in excess of 400W.

There has been liQuid cooling choice for some time offered by AIB's. I have trouble understanding offering a potentially third party liQuid cooler translates into engineering prowess or innovation for the IHV. There is nothing really new here.

LiQuid cooling has always been a welcomed choice -- and why AIB's offer it. If the point is more value for the potential AMD sku with a closed loop cooling reference solution -- can see this point but where is the innovation? Reasons for such hype and excitement? I'm excited about HBM or potentially architectural changes or improvements but actually disturbed a bit by the potential perception of needing liQuid cooling to tame it. Think this is a fair point.

Halo products may offer a perception for their entire products -- Too big -- Too hot - Too loud --- words that defined the first iterations of Fermi -- instead of investing into third party cooling solutions -- invested in architectural advancements and innovation -- focused on performance/watt -- seems to be paying off by revenue, margins and share. Lessons learned.

I think a reference closed loop cooling solution, while welcomed, offers some value, may be a band-aid on their disadvantages with performance/watt.

The reason industry keeps coming out with new methods and technologies for cooling is because they are addressing the problem. As you well know, GPUs keep getting more and more complex requiring an increase in heat dissipation over the same surface area. If a passive aluminum heatsink would suffice to keep a modern day, high end GPU cool then I'm sure that's all that would be in there. Instead, we have complex and expensive copper vapor chamber, heatpipe, blower equipped monsters. In fact, given the materials and complexity that go into modern high end GPU coolers, I wouldn't be surprised if a simple pump/rad solution is comparable in price to produce.

AIO coolers are just another tool in the toolbox for manufacturers to help dissipate heat.


Now if the water cooling isn't really necessary for the GPU and it's just an extra gimmick/feature/coolness factor that the GPU manufacturer uses to differentiate their products, then that is fine. All companies should try to differentiate their products. But if it's "required", that isn't the most ideal thing.
It should be obvious that the 390X won't require liquid cooling when dual GPU cards like the Titan Z and PowerColor Devil 13 (dual 290x) are fan cooled.

I wanted to check the scaling potential of the last GCN version and compared 285 vs 290 with the help of hardware.fr's benchmark : http://www.hardware.fr/articles/926-1/amd-radeon-r9-285-tonga-sapphire-dual-x-oc-test.html

Their conclusion was that the 285 was 30.2% slower then the 290 in average, and with 30% less CPUs (28 vs 40) this gives us an almost perfect scaling. The 285 consumes also +- 30% less power then a 290.

If we suppose that the 390X is "just" a big Tonga without other optimization and that there's no bottleneck not allowing the optimal usage of all CU's, this would place the 390X more or less on the same level then the TitanX (~30% from 980). It would also be around 350W.

Agreed, my WF 290 OC had no heat issues and my case sucks.

Quoted for truth. It's frankly quite absurd and reeks of personal agenda

So you think that the card's going to dissipate well over 400 W?

That's a courageous opinion.

Me, I have a modern case and a very nice quiet setup that is going to be happy to have more performance without much more noise because just like overkill coolers like the Windforce 970 I have now, it's going to be cool and quiet.

Because it's AMD that's debuting it, not Nvidia.

If your water solution gives you lower temps at lower noise with a higher perf/price than Air Cooling, then you are addressing the problem.

You forgot the lower power consumption that goes along with it.

The big concern some people have, myself included, is the idea that this "solution" is now increasing the footprint of the GPU in the system, now expanding beyond the idea of a double- or even triple-slot cooler in the expansion slot area, and going for space elsewhere in the system. Some will be happy with this, but you cannot tell me you don't understand why some will not be happy.

This isn't the same as moving from simply heatsinks to heat pipes to duct-forced external exhaust to more extravagant heatsink/fan coolers. This is now going beyond that, moving from direct-mounted cooler assemblies, to placing the brunt of the cooling effort somewhere else entirely in the system, requiring tubing to that place and taking up fan slots. In many cases, to maintain proper airflow, this may often require a user to already subscribe to the idea of closed-loop cooling, because some cases won't fit the radiator/fan combo when the user is using a large CPU heatsink.

I myself an limited in what I can do, and for these card+AIO packages, I can't fit them, at all. I find the idea that I have to change my CPU cooler to now accommodate a GPU cooler a little absurd.
I am looking at getting AIO for my top (crossfire) airflow-starved 290X Lightning, which to minimize cost and have something fit, that would have to be an H100. That allows me to keep my NH-D14, and that would fit above it in my case. I can't fit one of the thicker rads, and I certainly can't use a rad like the one in the 295X2 on the rear panel, not enough space at all with the CPU cooler.

My next build, which I might make with Skylake (which might be a fitting time to move from Sandy Bridge), I may transition that H100 to the CPU and a) have a motherboard with more slots between the primary GPU x16 slots, and b) have a case that offers more room from the start. Though the Corsair Carbide 400R is not tiny by any means, I rather like the size.

I find it very odd that people will spend over 1k on two video cards but will not dish out the money for a better case and then use that as a reason why AIO is bad.

We all know aftermarket cards will have none AIO options, why are people so quick to pick up the pitch forks and torches to bring down the AIO.

My case can't fit the AIO coolers that would be included with GPUs, like the one in the 295X2. It is a certain size, too large for my setup. An H100 is thin, and while it is a 240mm versus 120mm, it's thin.

Perhaps this wasn't addressed at me, but I suspect it was. I just bought the 290X's, got them both for about $650 post rebates.
When I put my system together in 2011, it was with SLI 560 Ti and an OC'd 2600K. I just upgraded my GPUs for the first time in this build.

I've also readily stated I expect there to be standard coolers released. I'm merely addressing the idea that CLC/AIO cooling is not a "natural evolution" for GPU cooling as others have stated, and spelled out why not everyone will be happy with such a cooler and need a different solution. I figured my own case would be fine, instead someone got all hot and bothered and apparently offended that I could ever let my system get into this situation. My bad, man, my bad.

The discussions of AIO vs air cooling kind of reminds me of the late 90's when the Voodoo 5 came out and it had active cooling vs the Voodoo 3 which was passive. Or the Geforce 256 vs earlier TNTs. While most were fine with it, there were some that called it out as lousy design. That however, was the difference in 11W vs being able to explore 30W+. AIO are being used to move to 300W+. I don't see that being sustainable. It may work this gen to edge out the competition, but we can't keep moving up the power ladder to extract more performance.

Sorry, your build is 'wrong' and is not compatible with how others here view a build 'should be'.

I feel your pain. This is why there (hopefully) will be a AIO/CLC option alongside a standard air cooler. The latter not being months later, either.

390x looks to be a GREAT card. Not sure how some dismiss a CLC-only option as 'not ideal'.

Why not ??? there is no law to prohibit increasing the power budget of the GPUs/CPUs/APUs etc.

There are people with triple of even quad CF/SLI using 200-300W GPUs, why not a single 400W GPU ???

Where does it end? Every gen we go up 100W? That can't happen.
