AMD Shows Off Silent A10-5700 System

[btarunr]

AMD Japan teamed up with ASUS to display a concept 100% fanless (silent) HTPC build to buyers at Tokyo's Akihabara electronics shopping district. The build uses Streacom FC5 chassis with a CPU base modified for socket FM2. The base conducts heat from the processor using four copper heat pipes to the aluminum chassis, which doubles up as a heatsink. The build utilizes AMD A10-5700 APU, ASUS F2A85-M Pro micro-ATX motherboard based on AMD A85X chipset, 8 GB of AMD-certified DDR3-1866 MHz memory, and Corsair Force GT SSD. The concept build shows buyers that AMD's "Trinity" APUs are ready, willing, and able to power silent HTPC builds.

nice

Kinda cool. I really hope AMD shows more and more of these niche item's that these APU's are bringing about.

So they've finally used my idea to utilize chassis itself as a heatsink... i like it. It's silent, efficient, dust free and also heats up the room nicely during the winter.

Now they need to figure out the way to do the same for discrete graphic cards so they can still be rather simply replaced with new ones. That would be awesome.

[Mussels]

not bad, using the case as the heatsink.

[NeoXF]

Sexy...

[damric]

heat pipes to the aluminum chassis

oh, yes.

[RejZoR]

I wonder why they don't do the same for nettops... It would be far more efficient.

people tend to think a hot chassis means the unit is hot.


OMG THIS PLASTIC LAPTOP FEELS COOLER SO THEREFORE IT IS COOLER


i''ve seriously had people argue with me, saying that LCD monitors use more power than CRT - because they feel warmer to touch.

[HammerON]

Very nice idea

Cost, space, weight that's why. Forced convection is more efficient than passive.

that heatpipe array looks like a laptops

[Ikaruga]

sweet!

If it's already packed in aluminium case (some nettops are), why not use it as a heatsink and you don't need to stuff one inside... besides, it would actualyl be even lighter. Instead of having chassis + internal heatsink, you'd just have external heatsink and chassis in one piece.
Space? You'd only need it for heatpipes, not the heatsink itself.

A case as in a thin sheet of aluminium? I think you would definitely need some fins to increase the heat transfer. Besides, you don't have enough surface area for it to work, on top you have the keyboard, sides have ports and bottom needs to be removable anyway (and hot air rises thus rendering the bottom useless).
Maybe it could work with some very very low power CPU's but not with 35-45W CPU's and similar TDP ranged GPU's.
A good example are passively cooled GPU cards where they pack as many fins as they can, I never seen one that has heatpipes attached to a sheet of aluminium.

I don't know how you argue with people, i just tell them this is my line of bread and butter, so STFU. Works every time

[Animalpak]

now this is DEAD SILENT

[Bjorn_Of_Iceland]

Smexy. pretty sure I've seen the same thing way back before.. with an itx form factor I think (or was that a sound equipment). Also noticed, a horizontal slot is readily available.. would be sweet to place a fast GPU with it.

Streacom and a few others have already been busy doing it for years. The article itself mentions that the "CPU base" was adapted for FM5 socket and that's about all the modding that was done.

[tacosRcool]

I wonder how hot that case will be (literally!)

HFX mCubed has been around for 6-7 years and done cases with integrated heat sinks.

They must pay you royalties.

Probably not very hot to the touch. The heat transfer is over a very large area, it might feel warm at best.

[Medallish]

lol damnit! I have the case, the Streacom FC5-OD, with a blu-ray drive, I'm testing it with an A8-3870 as I'm waiting for the 5700 and motherboard to arrive! I'm literally building this machine and have been working on it before this came out :P.

Btw. the case works really well! Even with a 100W APU it's able to run without overheating, during idle it goes to around 36-40 degrees, and during games it gets about 63 degrees, although if I stress everything it can get to be about 70 degrees.
Personally I'm planning on forcing in a passive 6670 as well to run Hybrid Crossfire, this is however quite a task as the gfx obviously gets quite hot, and there's currently no way to use the case for the gfx as far as cooling.

Just to prove I'm not lying, I made this thread(On S|A) just before I bought the case.

*Edit* This case is the newer version called FC5-OD Evo or something, as it has the button in the middle of the Optical drive, and "only" 4 Heatpipes for the CPU, otherwise it's nearly identical.

this is what you are looking for:





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

[Casecutter]

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.
