CPU cooler stone age edition
Aluminium was discovered in 1827. The more you know
Was 1827 in the stone age then or not !!
NLwino The stone age started before modern humans had evolved. It ended 1000s of years and began millions of years before 1827
I think the point was that the end result looks like a rock somone from the stoneage might've made an axe out of, not that aluminium is somehow "stoneage"...!
Putting the Rock, in Asrock
That moment when you give up... and you put a ROCK on your CPU!
Reed Elenz lol i almost choke on my pizza reading this 😂
HAHAHA
thermal conductivity of materials
Diamond 1000
Copper, solid 400
Aluminum 205
Rock, solid 2 - 7
lol i hope they make a diamond one ^^
hahahahah.. That was my thought as well. :)
from all the previews and thumbnails I thought that it will be an actual rock
im pretty sure that the guy from primitive technology can do it better with only some wood and stones
That's a severe burn. If only they had a better heatsink to dissipate the excess heat.
i don't think so ......

So bad is it not.
Should do a Liquid cooled system that uses a full sized car radiator
They did in one of the Scrapyard wars
EDIT: with a car heater core
Brandon Cline stfu nyan
it wouldn't matter how big the radiator is. It would ultimately be limited by the ambient temps.
op3l yeah but it wouldn't heat up as easily
So then why dont they use tiny CPU heatsinks in cars instead of massive radiators?
I hope this series progresses over the years until Linus and his gang create their own self-made sketchy computer, complete with weird ternary CPU with worse performance than the Intel 4004 and papier-mâché case.
angryDAnerd wouldn't be surprised if they eventually made a salfmade computer that does less functions than a $1 calculator, is harder to use than a stock Altair 8800, and would probably be blown out of the water by ENIAC, yet requires a whole air conditioner to cool
Search Ben eater
Too much off-the-shelf components. Search for Jeri Ellsworth
If all you're going for is a calculator that doesn't have to deal with storing data or loading programs, it's actually pretty straightforward. You're just describing what amounts to an ALU and a keyboard taped to a 10 digit display. The knowledge required to build something like this "from scratch" (i.e. from raw logic gates on breadboards and wires) is taught in university computer science courses. I got it my first semester of Sophomore year.
You joke but that's not actually that absurd. Yeah they won't be able to build a machine that runs windows but the expertise to build from scratch a simpler computer is a pretty common thing for computer science students to learn at university. Say you wanted to implement a subset of the MIPS instruction set (as opposed to ARM or x86, the popular instruction sets for phones and computers today), I had a class second semester of sophomore that was all about the hardware/software interface, and the textbook walked us through doing just that. We designed (but did not physically build) a CPU that could add, subtract, read from and write to memory, and branch (make decisions).

Working with a lot of engineers and development teams I can say that "Our engineering department realized that he needed to do something" is exactly what engineers do, If they didn't then they would just be conceptual designers.

You ... can't just pour metal on top of PLA... you have to melt out the PLA in a forge and wait for it all the drip out. Like ... did you guys even research this before you tried to do it? XD
Research? RESEARCH??? We're _men,_ we figure out how to do things on the fly!
Also they should have used a liquid casting clay, not "green sand"
I know nothing about it but even I was skeptical one should just pour the metal on it. Felt wrong.
Why would they research it if the point is that it's SUPPOSED to be terrible, and because it's bad it's funny? The title is called "sketchy heatsinks." They weren't really trying.
Yeah, I was wondering where they thought all the liquid PLA was supposed to go.

To be the "No Man's Sky" of heatsinks, you would have to keep updating it for another 5 years to finally include the features you originally planned, in all fairness ;)
they promised a golden turd and delivered diarhea
And like No Man’s Sky, noobody except those emotionally invested cares by that point
Holy crap, a video whose clickbait title actually lives up to my expectations :D That "heatsink" was just hilarious :D
The problem with stuff like this (and the reason manufacturers prefer milling the aluminum blocks using CNC instead of casting) is all the fine details (which won't cast too good using the methods you've tried). You might want to give it another try using a 3D printed part, casting it into plaster of Paris (adding the heatsink upside down), melting the plastic out of the mold after the plaster hardens, then drying the plaster in the oven for a couple hours (to drive out as much moisture as possible). The best is to keep the mold hot in the oven right until all the aluminum is melted (and you're ready to cast). This will give you the finest details possible with casting and the least amount of cleanup. And if you do it well, the result might actually resemble a proper heatsink even :)
I'm looking at attempting this myself but with a water block. Though, I have had fairly good experience with proper casting for small statues and jewelry, so hoping those skills convert over to water blocks. Jewelry investment captures such small details that I have actually accidentally captured my fingerprints before when casting a ring, it was from me packing clay at the base to form the reservoir. Plaster of paris may work, but I've heard it's components break down in the heat required for a proper burnout, so you risk cracking if you try to burn it out (burn off the PLA/ABS/Wax into carbon and then into CO2). If you don't do a proper burnout then your detail capturing and surface finish will likely suffer.
I'd agree about the mold though. There are casting temps suggested per material being used. The temps specify the best range for both your mold (flask temp in jewelry casting) as well as the casting temp for the metal. Beginners make the mistake of trying to cast as soon as it's liquid, but that isn't usually the proper pouring temp. Too low gives you poor casting details as well as risk an incomplete cast. Too high causes more oxidation issues, more gas absorption causing gas porosity, and potentially shrinkage porosity. The temps get more complex when you're discussing alloys too.
You also want to be mindful of the cooling rate so that you get the proper metal grain structure.
they don't machine heat sinks afaik, either they press thin sheets over heat pipes or they extrude a really long heat sink shape and cut it into pieces.
dat cooler deserves RGB lighting

Nothing could make that sellable.

Casting technique tips:
For best results run the following early stages simultaneously due to low success rates of you amateurs:
PLA print with the riser designed as part of the print> sand and smooth surface with added filler (wood filler or wall filler) > Silicone mixture vacuum chambered to remove air bubbles > set the PLA in the silicone mold > carefully cut out the PLA and close up the mold (single axis of cutting if possible and through the riser) > Melt wax and vacuum to remove air, pour into silicone mold (set in fridge if its warm weather) > Remove wax and inspect quality to pick the best ones. > (optional dip into a fine plaster mix and set to capture a good surface finish) > set in a vacuumed plaster mix (if coarse is easier to get, use the last step) > once the plaster is set turn it upside down with the riser over a borosilicate glass container and roast in the oven for a few hours (3-5) to melt out the wax and get rid of moisture. disturb the mold often during the first hour to make sure all the wax is out of the mold and remove it from the oven. > whilst mold is still hot pour in the molten alu.
don't forget to tap the molds a bit during each casting stage to remove bubbles between the thin fins in any poured substance such as the wax, the silicone, the plaster, the aluminium- this is why the sand is useless and it sticks to the surface. Course sand/viscous clay mix that you used would not fit well between the fins.
For quicker less shit results:
PLA print with the riser> sand a little > make a plaster mold > once cured, burn out all the PLA, just use the furnace setup until there is no smoke coming out of the riser (might take 20 - 40 mins) > wait for mold to cool a little and wash with some water > repeat burning and washing if required > roast in the oven for a few hours (3-5) to get rid of all the moisture > pour alu whilst still hot.
The plaster molds aren't reusable because you have to break them. so don't use much more than you need. PLA is low density so think about how you want to secure it in place.
If using the quick method and you have access to ABS capable printer I would suggest printing in ABS and using acetone to dissolve it and pour it out rather than burning it.
Get some casting quick release sprays as well, its a lot easier to remove cast items without damaging them, especially for the wax inside the silicone.
The plaster might be a pain to get out of the cracks so here are some plaster removing tips:
- cool it down (liquid nitrogen works well) or heat up a bit, shrinking and expanding the aluminium will help loosen the plaster between the fins.
- Ultrasonic cleaners
Why are you casting a heatsink?
Mill it and it would be done in a few hours and much cheaper assuming you re-purpose your 3d printer with an attached milling drill etc, much better surface finish, thinner heatsink fins.
"Sketchy Heatsinks"
dissidify its gotta be sketchy
Acetone for the win. Though in my experience they would get a pile of ABS mush not liquid. But maybe I just have not had access to a large enough amount of acetone. *Looks at glass milk jug full of acetone*
I think I meant melt out the majority of it like the wax but ABS is too viscous to remove it all. Then fill up the mold with acetone to dissolve the ABS that has coated every surface. I haven't tried with such a complex shape of fins though so I don't know how much ABS would actually leave the mold.

would of probably achieve better cooling if it had. XD
yep I agree
Please, for the love of Hoth; if you ever attempt to do any casting, do not use any wet sand or moulds. Aluminium is cast at relatively low temperatures, but even then the risk of steam throwing around how metal is real. If you cast other metals with a higher melting point, this is actually on of the biggest dangers. Water and metal casting do not mix. A steam explosion is always nasty and a steam explosion that throws incredibly hot metal around is even worse. Be safe!
Sagrotan don't be a spanner they're obviously taking inspiration from Top Gear, scripting projects to go as badly as possible for our amusement and to make us feel superior
Thank you! I cast bronze so even a little bit of water on the ground can result in craters in the concrete.

...what the hell are you going on about? if you want to make fun of minor spelling mistakes then make your comment at least somewhat legible... trolling 101
I'm actually in Trolling 202, and the first subject we covered was sarcastic illegibility. Trolling 101 was super easy. I actually made the honor troll. In fact, my academic performance was so spectacular that the dean offered me a job and requested that I teach Trolling 101. So really, I am in con-troll of what is and isn't taught in that class. You sir have no such authority.
Next time (if there is one) just flip the foam model upside down to get it into the fins then pour from the top
Not to mention, sort out that horrible "green sand" mush. That was so terrible.
Justin Gould
I thought my green sand was bad, but Linus had to go and make a pile of goo.
Lost foam casting even works with dry sand.
Come on, man. Just use a whole engine block next time. Maybe... just make part of it fit first.
Oh. Use a car radiator too.
Slaxbox
Nah, it has to be castable aluminium. Hdds bodies as prefferable to an engine block. Has lower thermal expansion due to the added silicon, helps with casting with greater presision and avoids thosed holes linus had in his heatsink
when doing lost pla casting, you're supposed to melt away the pla BEFORE pouring the melted metal
I would have went with 2 stage , low temp plastic casting , would have been much easier and better results
ikr
Red Ninja dont know if true. makes sense. ppl dont research
well, yes but then it would have not been such an epic fail.. And that is a whole lot more fun than a partial sucess...
they did attempt to melt the pla away...
I laughed so hard at the casting joke in the beginning. 😂😂😂
cody phillips same
SAME!!
1:07 casting couch teens lol really...
It looks so dumb in the computer lol
Linus, when you want to make an aluminium casting, you have to compact the sand as much as possible to get a very dense sand. You must also provide an air outlet and a pouring hole.
that blowtorch was a waste of money. make a metal forge, which only needs a large clay flowerpot and some cement, add fans for air and burn charcoal, and you can cast a lot better
I was thinking similar. 5 minutes of youtube searching isn't hard
"A face that only a mother could love"
Damn.
Just like mine... *feelsbadman*
Apocalypse YT Rip heatsink
If I were going to make a curiosity-driven DIY aluminum fin heatsink, I'd try bolting some flat stock together. Two sizes, one the thickness and width of the fins, and the other the thickness of the desired spacing and width of the base overlap with the fins. Getting a good thermal bond between the layers would of course be very important (right surface finish, clamping force, and maybe thermal compound?), and machining the base to be flat seems like a good idea. Aluminum angle on the edge would allow for easy mounting, though there are many ways to go there.

Or maybe just use the radiator from the car they took the engine out of for a watercooling setup.
Water cooling's so last year, nitro cooling the new thing,
"our engineering department realised HE should produce something useful" why am I getting so many Cave Johnson and Apperture Science vibes??? XD
You guys made this so much more difficult than it had to be.
I absolutely fucking lost it when they piled on a small mountain of thermal compound. Completely ridiculous.

It's like the silver surfer took a giant shit on his die to let him know what he thought.
All I have to say is that was like Everest to an ant.
Jennifer Lynn esp since luke did video on that
well, it base of that heatsink wasnt flat in any way shaper or form, using that amount of thermal paste would fill a lot of those gaps if they can remove trapped air. without a lot of paster that heatsink would have very little contact with the die. its not a machined piece of metal like actual heatsinks.

Should have dipped the PLA mold in ceramic slurry, layered it up super thick (by letting it dry and re-dipping over and over), then fired that to harden the mold and melt the PLA.
Then just pour into it, and as long as the sprue and vents are in the right places, you've got a heatsink.
Or start with a block of aluminum, use a bandsaw to cut regular slots for fins, then sandblast the hell out of it-sandblasting more as you approach the distal ends of the fins to achieve a taper. If sandblasting doesn't work for that, sandpaper definitely would. Simply insert paper, and pull toward the end. That way the distal ends are being sanded by the entire stroke while the proximal ends are sanded much less.
Oh well, I'm four years too late, but it isn't as if typing were difficult or time consuming. I enjoy it.

So, when casting glass, we use a mixture of silica and plaster. The silica softens the plaster so that it can be more easily chipped away from the cast product. With this you can use materials like wax to create your positive, and melt out the positive before casting the metal. Once your mold has an empty hollow, you then have to bake it in a kiln in order to remove the water from the material. If you are pour casting you could then take the hot mold from the kiln and pour in your metal. It should flow into all the nooks and crannies very easily, assuming you use ventilation holes to let the air escape from any under pockets. This is also result in a finer surface texture (once you get all the plaster off) than sand.
As far as the engineering/casting tips you were anticipating: First, your green sand mixture was WAY too wet. it should be**JUST** *BARELY* sufficiently moistened with oil to hold a shape when squeezed in your hand - that is to say nearly dry - with NO clay added. second, you might consider inserting pre-cut lengths of aluminum strapping (available in 3in' x 3/16in x 3ft straps at your local hardware store) into lightly packed green sand in one half of a two piece casting frame, level with the sand surface, then packing down the sand FIRMLY. Next, in the top half of the two piece casting frame, also in lightly packed green sand, In the area corresponding to where you inserted the the lengths of strapping to make the fins, create the contact pad of the heat sink by stamping a void into the sand with an appropriately shaped piece of wood. pack the sand FIRMLY & be certain it's level with the of the casting frame's top - this applies to both halves. flip the top half of the frame in order to cut your sprue/riser holes. ascertain there are no loose particles of sand inside the casting area & assemble the halves & secure them together. Pour the mold. You want the molten aluminum as hot as possible, in order to melt the edges of strapping exposed to it. It's kind of cheating to do it this way, but it should create a good bond between the fins & seating area. Might even be a good idea to have the exposed tips of the fins protrude into the casting void by perhaps 1/4 inch. Hope this helps...
That casting couch joke was absolute gold!
Actually, it was aluminum.
It was joke? I just wasted hours of my life.
Like Linus's hands.
Try soldering aluminum foil onto a processor. My friends cousin's sister did it said her iphone ran bloons better than ever.

Ben Bishop so your friends cousin?

bloons lolol
i love the way you explain that as a kind of tutorial as if ANYONE would EVER redo this haha :D its great man i really love ur guys sense of humor keep it up!!
For your second attempt at making a cast aluminium heat sink I would recommend you use the cope and drag method. Here's a very basic rundown of the process
Step 1: flip drag upside down and place pattern (heat sink) inside in the centre of the drag
Step 2: fill the drag with green sand an inch at a time making sure to pat it down in between each time
Step 3: flip the drag right side up and place cope on top
Step 4: insert the riser and reservoir, pack green sand around it
Step 5: remove riser and reservoir, remove cope, remove the pattern, draw gates connecting the pattern cavity ad the runner and reservoir
Step 6: place cope on top of drag and pour metal
Step 7: remove sand from cope and drag to reveal your heat sink
make sure to add draft angles to the heat sink fins so that they do not touch the green sand when you remove the pattern, you might want to use talcum powder to make it easier to remove the pattern (don't use too much though excessive amounts will lead to defects)
There's a few more details but I'm sure that your team can research the rest
Good luck guys!
I would love this to become an actual full series, maybe broaden it to homemade parts in general? I'd love to see attempts on other parts like water radiators, fans, etc.
Michael Low This is a full series!! they will make more, it will take long tho, cuz the fails :(

No no no, you got it all wrong.
You put the cpu on top of the molten metal so it fits the CPU perfectly for optimal thermal conductivity.

Have you tried sticking the plastic proto hs in that 6:34 upside down and then pull it off before the thing dries up, wait for it to dry and try pouring the stupid Aluminum in it?
Alright, you need some serious help here. Fortunately for you, I’m a foundryman and here to help!!
Your PLA will certainly work. Model your casting in solid works and print it out along with your gate and sprue system. Place in large steel cylinder that’s capped at one end. Your sprue needs to be longer than the tube. Mix some plaster of Paris and fill the tube. Once it’s set, simply invert the whole mold and bake it with something underneath to catch the melting plastic. Now melt your aluminum and pour it in. Wait 10 minutes, submerge the whole thing in a bucket of water to dissolve the plaster and cool the aluminum. Casting done.
This is painful to watch as someone who does aluminum casting...
You should give them tips to improve their process.
This was painful to watch for everyone involved. Larry. Moe, and Curly do Aluminum casting...
They need to watch some AvE. :P
This was painful to watch & I've only seen a few videos on aluminum casting. Just, like, did any research at all go into this before hand at all?
if there wasnt, thats not a problem is it
please contact "the backyard scientist " to make a more decent casting, he cast aluminum in all kind of staff, and i belive a coop video will be very very nice. He also have a slow mo camera for cool view points
Ohhh no. Call "Grand Thompson - The King of Random". He also coop this but HE MAKES ALUMINUM SO PERFECT! :D
YESSS THIS, I WANT THIS. I seriously was like what would Kevin think if he saw this video.
Tito4re also did lots of good castings on his channel.
Tasos Vatistas very good shout. wonderful if he has some good heatsink ideas
AND!!! He cast things with SOLID COPPER!!! omg I wanna see that
Hey just thinking about using the case for cooling which would be like setting everything inside the heat sink, it might actually be possible to provide a larger radiator surface area for cooling if of-course it's not all nuts...
You will have a lot better luck using 8 or so 2"x2" 1/8th inch aluminum plates bolted together with washers in between
A few notes
1) Aluminum Heat sinks are not cast but I guess you figured that out
2) Aluminum Heat sinks are extruded and then machined as needed.
a)Machining processes include drilling holes or crosscutting the fins producing a pin fin style HS
In my past life I worked for a major computer manufacturer and the way we would prototype an aluminum heat sink would be as follows.
1) buy a chunk of 1100 series aluminum
2) Use a Wire EDM or RAM EDM depending on Fin pattern
3) Machine as needed (note when machining use a cold gun to keep the aluminum from gumming up)
Who ever came up with the idea to cast aluminum needs to apologize to the staff who tried it. burns from Molten metals are bad very bad!
Yeah, it would have turned out fucking terribly if a bubble in that clay popped molten aluminum all over the people around the "art project".
Come on. The guy can't even use a reciprocating saw correctly. You're asking too much of him.
exactly
how many blocks do you think they'll destroy before knowing how to use the cnc I'm guessing 5
if you mean CNC mill, than it can be done with 6061T6 aluminum but you have better thermal properties if you use 1100 series. when you mill 1100 series it can heat up and the chips will load up the end mill and then fill up the slot you just cut and eventually break the end mill. if you use 6061T6 you have a better chance at being successful but only if you are making short fins. If you want tall enough fins you best bet is to use a wire EDM.

"hey man, stop linusing!"
"my girlfriend linused so much yesterday"
polymerizedrecords or dropping something expensive on accident.
"Oh crap, I linused my watch yesterday!"
Considering how LTT subscribers are, I wouldn't be surprised if this actually caught on hahhahahha
polymerizedrecords Post it on UrbanDictionary
@Vedal THAT would be linusing! ;-)
YES! :P
It deserves a proper name. May I suggest the LTT 212 CHUNK
More like the LTT 212 JUNK
tesla007 LTT 212 THICC
Shini Selune LMAO XDDD
GOOD ONE XD
I don't know why I laughed so hard at this
tesla007 LTT Evo THICC
when you talked about the warehouse it really made me want a tour of the lmg building

"not perfect by any means"
lmaoooo dont kill me.
looks cool!
You need to build a PC in the style of the Stone Age!
alex mutovin Yabba Dabba Doo!
alex mutovin use a pentium-90
He should just buy a console if thats the case.
Linus needs to do a "Sketchy PC Cases" series.
this heatsink would look right at home inside a pc case made out of stone
One o those cases for $30 that come with a preassambled PSU.
brick and mortar case with rock heatsink ?
That's almost just scrapyard wars
HappyBeezerStudios - by Lord_Mogul I think they call that a Dell PC.
The best part of this is that it looks like you glued some rocks together.
I learned casting 20yrs ago at school and what you did was so wrong in so many wans... funny! Stay with what you are good at... making such amusing videos.
Damn, and to think I spent all this money buying heatsinks when I could have simply made my own.
Matt Herdel or as they did just put a rock on it.
Thats a fucking rock
Oh Linus, Linus, Linus. What a fun video. I'm not a professional metal worker, but even I know there are some basic mistakes. Firstly, your crucible is too small to skim impurities, try a broader form factor then transfer it. More importantly, just like most manufacturing... you mentioned 'Pressure' for your casting.. (not being able to fill the cast UPWARDS). Even in industry to avoid using pressure to push upwards to create moulds (including Chocolate) you need to create the mould 'Upside Down'. This allows the natural flow to penetrate the fine details of the mould without pressure. Love the work tho, give it another try, I'm sure you could 'Crack' it wink wink lol.
Hahahaha... this could be an SNL sketch..
The reveal of that chunk of aluminum in an actual pc is hilarious.
who needs to spend $20 on a cpu cooler when you got yr own diy $100 cooler
Companies who make video content to feed their employees' families.
I would like this comment, but... (it had 69 likes at the time)
who needs a free stock cooler when you got yr own diy $100 cooler
Took way too long, preforms poorly, looks bad, no features as promised. Yep LMG product alright haha.
You spelled performs wrong...I'm only commenting cause the way you spelled it still works and me chuckle =)
Craftypiston you had me thinking about hello games for a while there!
if trying to fix grammar you should at least try to fix yours and use because and not cause
If you didn't get his joke there is no hope for you randomsprinkles.
if you are going to try to make a grammar joke like that it cant be that subtle where most people wouldn't even notice it
you should build a dinosaur-themed PC and this would fit right in.
I'm laughing so hard right now. Nice try with that heat sync though. The nomans sky joke slayed me😂😂😂.
a round of applause for the engineering team tho, thanks for trying
trying really hard x)
Loli I can imagine them receiving a 'you tried' star each.

honestly you guys were casting it wrong the fins should been pointed down at the ground instead of facing upwards
milodudeful why did this not get more likes?!
ikr
Wow 71 likes it would be nice to know if someone likes my comment THANKS UA-cam agh lol
it was easier to get a flat bottom this way
megaspeed2v2 nothing was easier the way they did it... lmao!
I'm thinking, along with any improvement your can find for your moulding, you could try working with copper rather than aluminum. It shouldn't have any dross problem, and you can source it easily enough from the plumbing section of the local hardware store.
With the foam one why didn't you place it upside-down so the metal could run down into the fins?
Anyone else think AvE should make a heatsink for LTT?
1MBStudios can't think of anything to joke about this.....
+1MBStudios You're joking right?
ave would make a kick ass cooler
idk man. After they tap a few holes, beat the crap out of it with a Swedish nut f*cker, and make some sort of A-dapter for all those Metreek fanboys out there, they may have a viable way to measure the Chooch Factor (TM). It will be a blond one away from breaking poor ol' Aida, but functional.
All through this video I was wondering what he would say watching this. I imagine it would be funny.
Why is there a *WHOLE DEAD FISH* in the engine block 3:04
Axe Avier hajahabahahahahahah
It's a heatshield
lol i see it now thats hilarious
That comment was hilarious. Props to you, you deserve top spot.
I thought the same thing when i saw that lol
Oh my God.
xD looking at that zoomed in shot of him using that rotator sanding paper hurts...The sheet isnt even rotatating.
Should have put the mold upside down so that molten metal runs with gravity into the fins from the base.
LMFAO! This was great. So the moral of the story is to just strap a rock shaped piece of metal to your cpu if you have nothing else and use and entire tube of ic diamond lol.
Keep making more vids like this, but maybe turn this into a 'homemade pc parts' section instead of just cpu coolers?👍
If by "home made" we mean with only what's in the average toolbox, it's down to cases and varying cooling options (and even fans would be borderline)... maybe cables. Add some basic electronics supplies and a PSU is conceivable, though perhaps not one you would want to use.
To clarify 'homemade' I only mean without the help of professionals (This doesn't mean they couldn't research or ask questions, just no out sourcing). They could use any tool that a person may have at home, I have friends that have fabricated tops onto their drill press to make them a basic mill. So outside multi thousand dollar specialty equipment, I'd say they could use whatever they want.
For other parts, the sky is the limit! Water cooling with stuff only found at a hardware store, cooling the entire pc with non-pc fans, custom cases, cables, dare I say a PSU! Some of these guys are engineers, so they shouldn't have any issue with this. I'm a senior in mechanical engineering at my university right now and all of this would be super easy and fun to make; however, would it work better than professional R&D pc equipment? Who knows, but that's fun part!
why not put the cast upside down in the sand so that the metal can seep through easier with gravity?
Then, if you're going to have to sand something down, you know where to start - the top, where it would connect with the cpu!
Bipolar- Bear Because they wanted the flattest bottom possible and that wouldn't be it
If they using an upside down model, I'm sure gravity would have filled way more gaps and it would have a way flatter surface for the mounting.
TheFPSPower Not the gaps that need to be filled though
as long as they have a bottom that cover ALL of the fin gaps, it would work much better, not even a question, I can find the answer to that in gravity logic.
Now do one where you use a rock as a heat sink!
keeping in mind, I haven't cast anything since high school and we used sand molds for the process (and this was about 30 years ago), the way I would of done it is, with a two piece mold putting in the proper vent and pour holes. The sand we used was just slightly damp, just wet enough to hold together then it was packed into the frame. The "heat sink" would then be placed in the mold, second frame added to the top of the first frame and then the sand would be packed in (gently, no need to pack too tight). The mold would then be separated and the master part pulled out of the mold while you make the pour paths etc. Then pour the aluminum into the mold.
An alternate method would I might try ; make a silicon mold of the part, then make a wax cast of the master and then use that to make your sand mold and just let the wax melt off like you were trying to do the PLA.
Your sand was way too wet and using clay? Liquid water is just a bad idea around molten aluminum.
I really would like to see you guys design a head sink and have a CNC machinist make it tho.
use tin foil next
if you can layer tin foil and fold it with a hammer or press into a solid structure than this might work.
Aluminium foil*
i foresee a lot of thermal paste...
That No mans Sky burn
Trying to think outside the (Noctua) box, how about using some old radiator cooling fins cut from a defunct A/C unit, refrigerator, or car radiator (any of which might be cheaper than a used car engine). Possibly solder/weld them to a square of aluminum or copper.
Lol casting....u needs couch lmfao that was sick Linus
