InfinitySink Development Thread - 2020 Community Influenced Universal Heatsink

the plates do not line up for unity and storm core dual. They made the wrong plate. The holes are off by just a bit as shown in the pic

all of the other ESCs fit without issue. Your TB6 escs will fit no problem

No need for expedited shipping on my end.

UPDATE:

The factory is unwilling to remake the parts (this is what I get for using a new place). So I will be making them at a place that SMFG works with (where we have our robotics shop). This is also where I have my CNC enclosures made.

It looks like I may be getting a refund for the bumass ones, not super sure what is going on (this part is not super fun lol).

I will just have to pay for shipping and stuff.

I am working as fast and as hard as I can. I am dhl expressing the new ones, so it literally could not be faster lol.

Again, if you need your heatsink now (not using unity or dual stormcores), I can ship your units now. And later we can see about getting you the replacement plate at a low cost (if you need it)

My order doesn’t need to be any faster, thanks for the transparency and update.

@surfnacho you’re good with my buddy, just keep us posted. I have a feeling once people start actually getting their heatsinks we can help chip in on whatever overhead costs you ate in the process

Thanks for your kind words, but this is my deal. I have to take full responsibility for this. Not a problem, I got you guys.

But its not our goal to leave you at a possible loss if you’re done with it.

I will not be at a loss. Thanks for your concern though.

Anyone know if this will work with the Maker-X Mini Foc Plus?

it won’t i guess, the hole pattern seems to be in weird places (for the heatsink)

Got this mounted and @surfnacho pointed out the other mounting holes :slight_smile:

So the plate attaches to the heatsink with these (4 x M3)

Is thermal compound recommended between the plates and/or under the ESC? I’m leaning towards not using it because it’s messy and seems to be a tight fit. Any thoughts?

there is graphene thermal pad if u don’t want to deal with the mess :joy: but i heard they don’t work all that well

Thermal pad will be beneficial. if you are experiencing thermal throttling without the sink I would highly recommend. Generally not using a thermal interface would be “wasted potential”

From what iI’ve read , thermal paste > thermal pads.
thats of course not always true.
I will be using Kryonaut on my setup.

In fact, I would highly recommend thermal compound between plate and sink as well as esc and plate. The sink isnt thermally optimal for a few reasons, though Im guestimating itll still help a good amount.

if anyone cares, the anodized layer is essentially an increase in porosity and if you learned anything in thermo (congrats) you learned that air is a shit conductor of heat ,in fact, thats how "insulation works. I digress though. The anodized interface needs help to overcome this and I think thermal interface grease will help a ton.

@surfnacho if you want to do a thermally optimized version of this at a later date and higher price, I would recommend polishing the interface surfaces and removing the anodized layer.

Funny I was about to ask if raw ones were available

Im getting conflicting sources on wether or not anodizing is good for thermal sinks… brb

from what i understand, emissivity goes up, but thermal conductance goes down,
so raw on the side with psychical contact to the heat source, and anodized on the fin side is probably the best way to do it. also happens to be the easiest combination of the two.

8x to 10x emissivity for oxidized over raw,

10x reduction for thermal conductance for oxidized over raw:

I guess the next thing to figure out just how hard is it for us is it to remove it from the inside for those that want to do it

My guess is fine sandpaper, a wood block, and a few liters of elbow grease
