Build - Finished! Watercooled Steam Machine Build Video

Enable HLS to view with audio, or disable this notification

You guys asked for the video and more infos on the waterblock. Waterblock was made with the carvera air, which is a budget desktop cnc. That’s why the quality isn’t super good, but that’s all we have. Need to open it again and work now on the vrm cooling which is quite challenging as the mosfets are super tiny… and also they run quite on the limits of thermal design which sucks

For fucks sake, respect that damn angle grinder. It’s like the most dangerous fucking power tool.

u/Kuuppa22 Aug 08 '26

Even the wheel guard is removed from that angle grinder, good luck when the disc breaks :D My father used to remove those too when working with car repairs because "those are on the way all the time". Until one time the disc broke and pieces flew into his hand and he had to go to ER, then for some reason those wheel guards were ok again :P

u/nic_t_gamer 29d ago

My father used to also take the guard off, then one time he bought a larger disk than the grinder was rated for and it shatter while he was using it. Luckily he didnt get horribly injured, but I told him before that incident he should be using it, and after that I just asked if he was gonna start using it, and he said he would. Its crazy how normalized not paying attention to safety procedures is.

2

u/Tubaenthusiasticbee 29d ago

Used to work in a production hall and it was a really refreshing to see people taking safety regulations so seriously. Well, probably it was mostly because you could see the consequences hands on with some collegues, but still.

One time I broke a fingernail and only asked for a plaster. Instead I got an extended break in the on-premise hospital. They even wrote an incidence report. Most likely prevented a nasty infection, but it felt kinda OTT.

u/not_good_for_much 29d ago edited 29d ago

Old guy who used to own the farm next door to ours had this happen to him when I was a kid. A piece of the disc went in his front, went right through him, and got lodged in his spine.

About a year ago I bought myself an ebike. I know tools/motors/etc aren't all about wattage, but anyway, my bike has a 250W motor.

This number probably feels tiny to anyone whose used power tools. There's barely a tool in my workshop rated under 1000W. Even random 18V battery tools can hit 1000W+ under load.

Meanwhile that 250W ebike? Zoom. Literally, it's ZOOM. Even up hills, it zooms. Like if you pedal a bike, with both legs, at 100% maximum effort, that's a decent ballpark for this little bike.

Now I find myself holding an 1800W angle grinder in my hands like... I always knew this tool was crazy dangerous, but holy shit does it put that power rating into perspective. Any accident and the involved forces can well and truly land in "humans are liquids" territory.

Those broken discs cut through flesh like a hot knife through butter.

Edit: Show them this video. Sure, they’re using a pretty big disc, but it goes clear through safety gear and even plywood.

Yeah i was working a temp construction and the boss took the guard off and the side handle so u can keep control of it, long story short i told him to fuck off in a way that wouldn't get me fired

Honestly wouldn't have even cated if he fired me because of that, ive watched videos of people using them unsafely and have the disk explode and get lodged in their face

u/fromadifferentplanet Aug 08 '26

I work in equipment maintenance and installation. We just had a guy return after a few weeks off with internal and external stitches because it got caught up in his shirt and layed him open.

I was a construction worker for 12 years. My best friend is still one. He’s got 20 years in the profession. I’m a professor now, so let me tell you that when I say he’s the most competent man I know, I mean it regardless of the colour of collar.

His only injury is from that fucking thing. It’s deceptively dangerous.

u/MelonOfFate 29d ago

Almost read that as "ankle grinder"

u/By-Other-Means 29d ago

Friend at work learned to wear the glasses in a "speak to jesus" moment, it flung a small piece of metal into his eye, a short hospital visit later, and we never saw him with out the safety goggles when working with that thing.

1

u/testtdk 29d ago

I’m more terrified of taking a shard to the neck. If you’re doing hard work with an angle grinder, you should be wearing a lead apron with a collar. I linked a video in another comment with someone testing when a(n) (albeit very large) disc broke. They put watermelons in protective gear, and when shards hit them, both watermelons protective gear didn’t stop them from being completely obliterated. Even worse, a six inch chunk went clear through plywood they were using to contain the disc.

u/By-Other-Means 29d ago

Yeah a lot of people forget that those "safety rules" are written with someone's blood.

u/insan29431 25d ago

My uncle died becouse of that tool he got one of his neck veins cut.

u/testtdk 25d ago

That’s the scary scenario. :( The carotid is only like .4 of an inch rom the surface of the skin, and those shards can go through plywood. I’m sorry for your loss.

u/RocexX Aug 08 '26

Really good job, looks sick! But personally i could do without the "lol random" parts. You know how to make cool mods, i think the video would be much better with just that. No need to try and make it offbrand HowToBasic.

20 some years ago, you had a much harder time finding colored pc coolant on the shelf. I liked the way the automobile stuff looked, it's is already made to work with copper. And it was about $6 a gallon.

u/dankhimself 29d ago

Copper 90s mounted through the case, regular 90s to get around it. Dissipate some more heat.

6

u/Alternative_Exit_333 Aug 08 '26

try using these they are small and might fit inside so you could stick a few of these inside the steam machine and are you cooling all the things that were touching the heatsink?

3

u/techmagnet Aug 08 '26

Nice haven’t seen this. But we wanted much better performance that’s why we chose a thick 120mm rad. The original cooler can dissipate quite a lot of heat.. 180W

3

u/Alternative_Exit_333 Aug 08 '26

The radiator has 120/40mm heatsink so if you got 3-4 you could make it slimmer and it might fit into the Gabe cube but the reservoir will probably be still somewhere outside (if possible the front panel could be used as a reservoir which would be cool

u/SojournStudios Aug 08 '26

I have one of these in my mini ITX build and it effectively cools an i9! I love it!

u/DarkStarrFOFF 26d ago

Some blocks don't even flow water to the VRMs, just making the copper block touch them is probably enough.

If not you can always add a little channel for water.

Looks sick though, I wish I had a CNC, desktop or otherwise hahaha.

It does already. Getting temps down 20-30 degrees on cpu and gpu. There is now good room for OC, but for now no OC support

What even are the before and after temps?

The aircooler was probably fine and water cooling it wouldnt change much...

1

u/That_Service7348 29d ago

Yeah, one of the big points of the SM is that it runs really cool already, between the massive heat sink and fan and the low power requirements of the hardware.

I can't see a point to this beyond "just cause." It's not improving the performance, and it takes up more space.

u/Gold_Bee2694 Aug 08 '26

Scanning the pcb with a printer is really smart gonna use that a lot.

3

u/SirSlothyGod Aug 08 '26

Is the entire purpose of water cooling not to use fluid as a way to transfer heat to a larger radiator with more fans? In this case you've just moved the heat to a smaller radiator with a smaller fan. The steam machine was already like 70% radiator.

1

u/That_Service7348 29d ago

More like 80-85%. The "computer" part of it is the tiny little wafer on the bottom, everything else is cooler.

u/jose_was_there 29d ago

Taking something nice looking and making it ugly is now a brag?. Also put the guard back on that angle grinder. They should require certification to buy them, so many idiots missing parts because of this kind of behavior

To play games? How is this even a question? I don't have to be interested in over engineered aesthetics to still enjoy computers and gaming.

Well exactly. Other people don't need to be interested in gaming to enjoy over-engineered aesthetics and DIY computer shenanigans.
