    Video here.

    What really interests me is that crossfire works and they show the silent RX 460. While it is certainly more cost-effective to buy a RX 480, with two silent RX 460s, a Nofan cooler, and a fanless PSU, you could have a totally fanless gaming rig that can hold its own.

    Cool that it works. It would be interesting to compare against a rx 470 and having the shaders unlocked to 1024. The main reason is that the rx 470 has 2048 cores vs 896/1024 so if it would be cool to see the real potential gains or losses that crossfire introduces ;) .

    Don't get me wrong I am digging my rx 460 in the htpc, and it is holding its own in 1080p. However with a couple past deals you could score a rx 460 2gb for $60 after rebate vs a 470 4gb for $125, so the value proposition is not exactly there unless you come across 2 cards.

    And all the times CF doesn't work. There is in reality no value in RX460 CF and its just plain silly. You just buy a RX470.

    You can't buy a silent, fanless, RX 470.

    An RX460 is a pretty powerful solution for a silent, fanless setup; but I'd still be leery of attempting a Crossfire build unless I'd already mapped out the applications to be used and ensured support. For a general gaming rig, this'd be a no-go, and I'd be looking to find a quiet but not necessarily silent single-card solution with a little more oomph.


    (on the other hand, if a single RX460 is enough, and for many popular games playing at 1080p it most certainly is, then having the second card around for only some cases wouldn't be that big of a deal, if silence is paramount)

    Putting 2 fanless cards next to one another is a pretty bad idea. Also cards are not fanless as such, they require airflow from somewhere else.

    You can make a fanless 470 is you wish.

    And again, RX460 CF isn't going to perform like a single RX470. You also sit with 2 75W cards vs 1 120W card. That's 30W more heat to deal with in your "silent" setup.

    I dont understand how it will be fanless and not catch on fire. Cpu generates heat, psu generates heat, two rx 460s generate heat -- it has to go somewhere... The rx 460 i put in my fathers computer... fan runs pretty hard while gaming. Also, i still have not yet found a game i want to play that ALSO supports crossfire -- so theres that too.

    Project cars for example i get 45fps with a R9 390, for the first time since geforce 9800 gt i find myself about to switch back to nvidia

    thats very true seems games devs just dont care to get crossfire working anymore.

    Put everything in a rotated case like the Silverstone FT02 or FT05 and the heat goes up and out. Convection rules.

    also could use some low rpm 140s to push air thru the case silently. I just redid my file server/transcode box and only put in 140s and its silent now and running super cool idling at 20c right now rooms 17c.

    Depending on the case and air intake it won't be that bad. Enterprise servers do it all the time.

    Yes, with 10000-15000rpm fans and AC :p

    I guess it's cool that it works from an academic standpoint, but it would be really pointless to do this in a real system when you can get an RX 480 for probably less money than two 460s.

    You think that our forum users cant figure out what they need? Also some of these cooling systems are fairly anemic for the hardware in them. I think you are greatly underestimating what the hardware can take and what our users are capable of building.

    Not sure how that is related to context since you mentioned enterprise servers.

    But its certainly easier to do a passive RX470 than 2 passive RX460 on the DIY front and you avoid 30W of heat assuming CF works to begin with in the app/game. And as said, RX460 CF serves no purpose besides from an academic standpoint.

    You did not respond to what I said at all.
    Also some of us find configs like these interesting. Hell I know I have run SLi low spec cards for fun before.

    You make it really hard to understand the flow of the conversation when you ninja edit like that adding more content than originally posted.

    If enterprise level systems (shit hardware for most companies) can maintain dual passive K80s with dual 2660v3s passively cooled by 6 tiny fans (Some DCs dont even have active cooling, I work at one like this) and some moderate AC, then I have no doubt our forum members can plan out the exact amount of air flow and AC they need in order to have said passive system.

    Dunno why you wanna shit on this thread so hard. I hardly ever see you shitting on SLi this hard when people are going dual Nvidia GPU.

    You may work in the only datacenter in the world without active cooling then :)
    The fans may be tiny but that's why they spin at that rate,

    Maybe because there isn't any threads about someone trying to SLI 2 90$ cards instead of buying a single faster 140$ card instead that uses 20% less power and have no problems associated while having twice the VRAM.

    For the passive RX460 with 2GB its 105$ a pcs. And 130$ for the 4GB.

    You can get a long way with a 140$ RX470 and 120$ extra to make up a passive solution if that's a must.

    You think my DC is anything special? Lord no, this is hardly the only DC in the world like that. Hell if you knew who I worked for you would probably re-think Data Centers entirely, as all our new buildings operate without active cooling systems. Then again, I guess you can research the best stuff when you are number 1.

    And you think no one ever made a thread on [H]ardOCP about SLi with two low end cards.... Thats a stupid assumption. Perhaps you should dig a little deeper into the forums before suggesting something so insane.

    Please send me some info about that type of datacenter. And yes I do work with it. Datacenters here generate so much heat its used in district heating infrastructure as well. :)

    Example:

    We are not allowed to share much information about our DCs. Not even photographs.
    Please though, next time people are genuinely curious as to what two low end cards can do, dont shit all over the thread.
    No one needs to be reminded that a more expensive card would be faster. You miss the point of the thread if that is all you are thinking.

    Way to narrow down on a niche, and create another niche within itself.

    Why does it need to passive if you can just find a card that runs quiet?

    Fun fact: a passive Zalman CNPS10X Performa have trouble cooling an i5 530 under 100% load.

    The same cooler with 1200rpm fans can cool a FX6100 at 4.6Ghz no problem.

    The video was done with 4gb cards which are 100 bucks ish, making two not any sort of deal at all.

    This is like putting two inline 4 in your rat rod, when you know the cheap V8 will be a much better deal.

    You are artificially limiting yourself just because you wanted to have 2 fanless GPUs that only give comparable performance when crossfire is not broken.

    How about 3 460's in CrossFire?

    While, yes 2 460's would fall short of one 470 in virtually everything except one: Some folks need a lot of monitors, so having extra cards for that purpose and yet have option to use both cards for CFX (limited to the monitors on the master card) may interest a few (how ever small that may be).

    i used to love to crossfire 2 cheaper cards but as of late its hard to find games that are coded for them and have crossfire profiles, it seems that games are becoming console garbage that is never fixed or optmized on pc and we just need the strongest single cards to brute force our way to high fps.

    I guess there are two types of datacenters then...

    Tier 4 Centers (Where I work).
    And people playing they are runnning a datacenter...no wonder our business is expanding, thank you for making it so easy :)

    The arrogance is strong In you. But regardless of what you'd like to believe the data center I'm describing exists and is hosting Netflix right now as well. Among many other things.

    Maybe you should read up on it, or get some more experience in the industry before telling others what exists and what doesn't.

    https://www.google.com/patents/US9414531
    "A modular computing system for a data center includes one or more data center modules including rack computer systems. An electrical module is coupled to the data center modules and provides electrical power to computer systems in the data center modules. The data center modules do not include any internal active cooling systems and cannot be coupled with any external active cooling systems. A data center module directs ambient air to flow into intake air plenums extending along intake sides of the rows of racks, through the rows of racks into exhaust plenums extending along exhaust sides of the rows of racks, and out into the ambient environment to cool computer systems in the racks. Directed airflow can be lateral, vertical, at least partially driven by air buoyancy gradients, at least partially induced by air moving devices internal to computer systems in the rows of racks, thereof, etc."

    "wherein, to remove heat from the one or more rack computer systems in the respective data center module independently of any active cooling system, each of the one or more data center modules is configured to direct a flow of ambient air from an ambient environment, through the front face, through the row of rack computer systems from the front end to the rear end, and back into the ambient environment via the rear face."
