CNC Routing service for custom, low-profile copper heatsink? 🤔 (and maybe some AutoCAD help)

[Jaeson365]

Good evening/day all

First, a little laugh at my ignorance, till now I did not know where the "General and Off Topic Discussions" sub-forum had gone since the forum was redesigned. Facepalm.

But, I'm here now and I want to "tweak" my laptop's cooling and so I call upon your combined wisdom...... inb4 repaste/laptop cooling pads/propping the laptop up/cleaning it etc.

So:

-> I'm looking for someone who can recommend/assist with CNC routing services (for copper).

-> I reckon I can get the copper, no problem (but if someone has suggestions as to where/from whom please chip in)

-> Preferably in the Gauteng/JHB area (but if I have to courier back and worth, I will - looking at you @ENDU1997)

-> The heatsink will need to be low-profile - as in < 3mm but, if I have to provide something thicker and then sand it (or something) I'll make a plan (side quests...)

-> Ideally something similar to what is pictured below but with much smaller fins.

-> I'm working on the design/shape and will upload what I have when I'm satisfied with my effort. (if anyone thinks they could put it into AutoCad for me, please give me a shout)

• If there's something I've left out/ more info I ought to provide... please let me know!
• If anyone know where I could get heatpipes locally please let me know.

Please, let me know your thoughts!

Hey guy,

Super cool that you wanna do this yourself but I'd recommend going far more precise. Most CNC routers wont give you the best finish or cut. For something like that I'd actually recommend using a wire cutter/eroder. They are extremely precise and the cuts are super smooth. As far as sanding down, a surface grinder would provide the best thickness uniformity although these options are a bit more expensive but will def give you the best possible results.

I'm super happy to draw this in SolidWorks for you, just send me some sizes and viola. I'll give you detailed drawings and 3d models to use

I've worked in a jobbing shop so am familiar with things like this.

What are the dimensions? It might be possible to buy something off the shelf, and would be a heck of a lot cheaper

Did you find someone who does it? I might be interested in this service too for a VRM heatsink

@Spectaitor @rinners

Thanks for the input gents.

For the sake of... completeness, I just want to update you

What I ended up doing was getting a heatsink for a similar model, one that has a copper fan shroud, copper radiator and PCH heatsink.

The result is 8-9 degrees drop on all cores and PCH when using Small FFTs (max heat) in prime 95.

If you don't need funny shapes cut - i.e. if you just want little squares (or big ones I dunno) or something, I recommend these guys Copper Sheet Metal

They cut some pieces for me to overlay and they did a great job.

So no CNC stuff to increase surface area?
