Before I'll tell more about noise assassination in the setup I'd like to tell a bit more about the heat sink, hope you're not tired of it. Well designed radiator is great and all, but it remains vaporware as long as you don't consider technological pipeline and the goal of commercial availability of the product just makes everything even more difficult. First thing that comes to mind is CNC milling thanks to its incredible versatility. But machining process takes a lot of time and, more importantly, money. Would be fine for one unit, but if we're going for a small series — it would be a disaster to make. All other processes require serious industrial involvement: casting and extrusion so I chose the second one for one main reason that is always on my mind: scalability. That's why I've divided one big-ass heat sink in segments by the way (and it looks just sick). The main difference between casting and extrusion for us in this situation is that casting mold is static and can't be changed, you will always get what you've ordered. Extrusion, on the other hand, allows me to order profiles of different length depending on my needs. So now I have a way to scale the surface area in two dimensions (even three if you'll consider snapping two profiles together smile.gif ) for little to no additional investment.

As a bonus for all the subscribers biggrin.gif - here are some shots of beautiful machines from our makersspace that will help us very soon with manufacturing! Stay tuned!



You guys got a factory, not a makerspace! tongue.gif I'm used to see makerspaces with drill presses and some lowly 3D printers, but you even have an articulated robot! Are you going to manufacture everything with the CNC routers? Is the arm involved somehow?

Haha, yeah, it's really packed. We will use water jet cutting mostly, heat sink manufacturing will be outsourced cause, well, extrusion is not really a "makersspace" thing biggrin.gif. 3d parts (like manifold) will be CNC machined. Not sure if we will need that ultracool arm, cause there are no parts *that* sophisticated, but it surely look awesome as hell, so why not show it off biggrin.gif

Thanks all for your responses, we're really working hard right now to actually start manufacturing asap.

This is pretty cool! and those CNC's drool.gif

I have to say though. aluminium & water rolleyes.gif it never goes well from things ive seen people do.
you should have it re-anodised after all the maching is done & it will be ok i guess.

Now Bring on the machining Pron wink.gif

Hello, people!
Sorry for such a long silence, we've faced critical production difficulties with Menhir back then (basically our aluminium extrusion supplier bailed out for reasons) and we've spent quite some time to find a new one that will suit our requirements in terms of quality/speed/cost. And the end of the year was not the best time to do that at all, that's why it took such a long time to finally figure all the things out. Luckly we're back on track with the project, orders have already been placed. In the meantime lots of great things happened, like EKWB releasing wonderful monoblock for the GA-Gaming 7 series motherboard. Since we're big fans of EKWB here we've decided to downgrade our motherboard choice a bit to be able to utilize that water block.
really hope to finally feed you with some tasty shots from the production ASAP.

Thanks!

This is going to be amazing! biggrin.gif

Get out of my head! I'm also building a fanless high-end gaming PC. Major differences are: (i) I'm using all off-the-shelf parts, and (ii) heat pipes. Not trying to produce at scale and definitely not trying to use water.

Mind helping on a few issues?
i) What software are you using to model the thermal performance of the heatsink?
ii) What software did you use to render the images?

Thanks and good luck!

Would be interesting to see what you'll come up with! Do you plan to deassemble market heat sinks to get heat pipes?
As for your questions: I use Solidworks Flow Simulation and Keyshot 5 respectively.

Thanks! Heatpipes are fairly easy to purchase separately in various lengths and sizes. I won't disassemble anything for them. The real challenge is finding the blocks for GPU and CPU!
post #49 of 95
Here is a source for heat pipes: https://www.enertron-inc.com/online-store/heatpipe.aspx


Does anyone know where I can find copper heatpipe blocks for the CPU and GPU? I think they are called "cold plates" or "condenser plates".
post #50 of 95
Are you looking for the normal blocks with micro channels or those with a copper pipe running inside a block? Or are we talking about those pipes used in Streacon pc cases for fan less operation?

www.myheatsinks.com could also help.
