AMD Shows Off Silent A10-5700 System

Where is the PSU ? This box cannot possibly draw more than 150W with everything maxed out (and is mostlikely under 100W, APU consuming ~65W, motherboard another 15W, SSD consumption is in low single digits and optical drive isn't using much more than 10W either) which is perfectly doable with a passive implementation.

that heat sink look nice

The PSU is a powerbrick, 12V, delivereing power to a small board with a few VRM's that's actually on the ATX power connector(Also known as a PicoPSU), and it's usually a 150W with Streacom(The Case manufacturer), they could probably even squeeze in a 5800K as well, but I know from personal experience that, it would be to push that 150W PSU to it's limit. In my own very similar setup I'm planning on getting a 250W CarPC PSU and pair it with an HP 230W brick to deliver the juice.

Too bad the 5700 isn't out yet. Only A10 I'd want.

This is Not new; while here the problem. It’s like any machine you’ll need ample breathing room to dissipate the heat. Pack it in a cabinet behind glass door an once the ambient inside there starts to elevates none of that matters, your just transferring in an ever increasing environment. You might get lucky and level off at a safe level, but you do need to consider it’s placement.

this isnt a server that you will place into a glass cabinet. try to think practically.

and there are pretty low TDPs. so yeah...

afaik it's just as out as the rest of the APU's? I can see it's set to arrive in the stores here in Norway in 3 days.

this is what you are looking for:

but that prototype didn't make it to the market i think :/

damn that would so cut my hands!

There is enough cooling on the other side for a decent graphics card too.

the cabinet argument is a balancing act, to me the only reason to hide an HTPC is either because its an ugly scrap build of random parts put together just to get access to media, or because you just want to get it out of the way in an effort to cut down on noise. A system like this you could put on display next to your receiver (if you are the type to have that on display) or next to your gaming consoles. I know very few people who hide their consoles for fear of them overheating or just because it is easier to keep them handy for swapping disks.

But personally I have had my HTPCs housed inside an isolated cabinet from IKEA for years, and a variety of builds ranging from my original e1200 celeron up to my current 2100T + HD 6400 (2gb/128-bit) and though I've added some ventilation for the sake of having weekend projects overall I've never had any real issues. Originally all I had was just a 120mm hole on the rear of the cabinet that I used for the wiring to the receiver and the only fan in the original build was on the e1200 (HD 5450 I had paired with that was passive).

So if you had sizable passive ventilation, I'd wager this would do just fine behind a glass cabinet door. Modern systems do quite well at throttling at idle and in sleep mode to cut down on heat compared to older systems. And use an SSD in here, and keep your media on a NAS somewhere to avoid mechanical storage dumping heat into there as well. The OS SSD in my server typically runs a solid 5-10c lower than the mechanical storage dumps, even the 1TB Raptor in my main rig runs between 33-38 vs 29-35 of my 240gb Kingston HyperX. So you can imagine the savings would be much greater in a case this size compared to a Corsair 600T that has a 240mm fan right in front of the hard drive rack.

But I really am anxious to get my hands on these new APUs for some HTPC builds, and see if I can shave some watts off my current system. 2100T + HD 6400 is pretty efficient, and I'm really disappointing AMD didn't release any 34/45w TDP parts, but I guess some later binning or undervolting/underclocking might get us there without any appreciable performance hit.

*edit*
Also, you'd wonder if they would release a heatsink adapter that would let you passively cool a GPU that you could hybrid crossfire with the IGP using the cooling fins on the other side of the case? AMD recommends using an HD 6670 with an A10 series APU, perhaps that could be passively cooled? Sapphire and HIS both have dual slot versions that are passive, but I guess you would have to share the CPU-side heatsink to get that same kind of surface area...

considering those fins are not filed to not have a sharp edge

That's what I considered, although the problem is getting the right heatpipes, mounting, and will it even work when the heatpipes upside down? From what I understand they usually have a kind of gas or water in them, and won't work properly if they're turned around.

well Heat rises, there is no way of changing that physical attribute of that form of energy

 

[Medallish]

I wasn't refering to that, more the function of heatpipes, when "cool" it goes liquid and to the bottom of the heatpipe(the source of the heat), and when heated it "turns into" gas that rises to the contact to the fins that cools it down again, I know it has a more appropriate name other than "turn into" but it escapes me completely right now.

its the gravity effect. pretty much too

Yeah, so in order to use the same system for the GPU(Going by the Streacom FC5 case) the heatpipes will have to point downwards to reach the fins, working against the gravity effect, unlike the CPU connection where the cooling goes on above the CPU. I never spend much time in chemistry(Wouldn't mind having done that by now tbh ) But for such a heatpipe to actually optimally cool the GPU it should have a gas that reacts opposite, turns into vapor when cooled, and liquid when heated.

Reminds me of this old zalman case, the Zalman TNN-500A:
