We set out to build the world's WORST CPU cooler... and boy, we certainly did succeed...

How about you use mayonnaise as the thermal paste to make it even worse.

[mariushm]

Oh man ...

 

Why not just make a CUBE of aluminum, then polish the heck out of the bottom and then use a somewhat high speed drilling machine to make A LOT of holes in the top to increase the area of heat dissipation

 

Aren't those fins usually made using extrusion? I assume they have a bunch of hot melted aluminum and push it out through a die into a chamber that slowly expands in one direction , and then they can just cut pieces of the extruded material

 

Here's an example : https://www.digikey.com/product-detail/en/advanced-thermal-solutions-inc/ATS-H1-30-C3-R0/ATS-H1-30-C3-R0-ND/4624535

 

Seems to me like they make a long strip of this with the fins unseparated, then maybe they go with a big wire saw to split those fins into smaller segments and then they just cut out three fins from each corner, drill four holes and then put the piece through some polishing machine

You could also do one with a CNC machine :

I think he did something like that for a scrapyard wars once, this series is meant to be crap people could do at home, not many people have CNC Milling machines.

"Ambitious but rubbish"

Hey Linus, I think you're going to receive a letter from BBC for that one.

[Fiat-Libertas]

Metallurgy expert checking in (not).

 

In all seriousness, I really like the attempt at casting.

 

I have a feeling you could've gotten the first method to work. I think you should've used a different 3D printing material. PVA is water soluble I believe? that may have worked better instead of trying to melt PLA through sand with that torch.

 

Also you so you don't have to fuss with the oxidation layer forming on the Aluminum, I think you could trying running an inert gas over the top of it while melting (like you do with any welding).

[madaday]

Would it not have been possible to make the negative of the heatsink and 3d print it, then cast in the gaps?

the metal would have melted that for sure.

[unijab]

I wasnt surprised it took your gang of misfits several attempts...but I was slightly surprised that after so many attempts their casting skills didnt improve.

dont like his videos / style of speech

[Taf the Ghost]

Thank God, I thought someone was going to let Linus cast metal.  But, hey, at least you would have gotten the follow up videos, "How Linus burned down his own building", "Arson & Insurance Fraud for Dummies" and "Why Sandals are not appropriate safety footware".

[SukaroBlue]

Honestly you would of probably gotten more success out attaching a fan on top cup filled with water to "liquid cool" your cpu than trying to cast a heat sink in your first few tries.

[iPolymer]

I see that your new engineer was put into action, no design skills tho. It does look cool like a rigid nature build. I think Luke should use it on his rock personal rig to accent all the MINERALS,

this could be the next episode? 

[SCHISCHKA]

I would get a sheet of copper, cut it down so you have a stack of rectangles; braze each layer only in the center; then bend the un-brazed edges up at different angles.

 

I think you should try the mold again but this time put sheets of ali into the mold and then bake the mold in an oven. The kind of molding you have done is really good for making simple shapes out of lead like fish sinkers & bullets

[crzyces]

Linus, your team is bloody ingenious at times. This was not one of them. First, the kiln to melt. You should have known better. This needs to be done again correct DYO style (Do it Ourselves style). This will cost about $25 usd, and 2 cheap stock or whatever fits fans.

 

You need this http://www.onlinemetals.com/merchant.cfm?pid=1910&step=4&id=1414&CAWELAID=120293320000030460&gclid=Cj0KEQjwuZvIBRD-8Z6B2M2Sy68BEiQAtjYS3K_dhSFkipTlUbSxgAvGuXG0rYWdpsLH3tmgdrFg5GkaAk0P8P8HAQ

 

Before you solder, skip to the bottom

As simple as possible. 3.1" length, 2.9" width, .021" depth (the thickness of the sheet). Make 3 of them. On the bottom one burn in 5 horizontal lines as thin as you can, @ .003 depth (Essentially just touching and burning the lines, as we want the bottom to be the thickest, absorb, and conduct) another, but with a tad more pressure on the lines. Last, the same thing with a bit more pressure. So you have your 3 very thin sinks on top of each other. A dash of solder in each corner where they touch is perfect (Both sides). What the heck, you had a square foot to use! I have all this extra! Well now you are going cut and slightly heat 3 strips (They are thin so already pliable, but this will make it easier, 100 fh should do.) Essentially make an s with an extra loop, so there are 3 main touching points, the starting and ending of the strip facing away from the sink) in the middle of each sink. Solder those on.

 

Now you have a 3 layer sink, with 3 side strips, and 1/4 of the metal left. Great, extra!

 

Make 5 posts, one for each top corner, and one for the middle, hopefuly 1/2" high each (They need to be the same height). Lay 2 of your 3 last pieces of copper across, with another dab of solder on the sides. Place any standard size cpu fan atop your mini sinks (old, new, Intel, AMD, Suplus r US... it does not matter. Secure it (pick a way, drill, zip tie, cut zip tie and heat, solder excess copper, again, does not matter). Do the same on the side without the "S's + the U". At this point, you have a two fan, copper heatsink that will make a Noc 3 times it's size and 5 times it's cost say "Sorry, I could not hear you, I was too loud, and gosh was I sweating".

 

All it took was an expensive piece of 12"x12"x.021" foil, a butane lighter, a soldering gun, and two old fans. And some Butt Cream.

 

*Skip*

If you happen to be out of Arctic silver, I bet you have a better cooling solution. You have kids and you're a geek. I know you read the ingredients for the diaper rash cream. Probably not Arctic silver though. Have you ever heard of Triple Paste Butt Cream? A dab of the paste, a dab of Vaseline, and a dab of Artic silver, and you have the best cooling transfer paste available. The Zinc Oxide is the key, as you will notice in Artic Silver and Triple paste, they are almost identical, except the triple paste is higher quality and less corrosive.

 

I'd make the video but I don't have the equipment, and, well, am still a tad camera shy. I am quite smart though. Ask Jake and his buddy to look at the idea after you say "Guys, this is ridiculous, but makes sense". Oh, and no need for the kiln!

should have built something like this to melt the metal.

 

[Space Reptile]

you guys poured the wrong way round , you want the Fins to be the last Thing the metal reaches as they are thin and Long

 

[Duderino]

Now here is what ya should look into.  Just thought this one up.

 

Should have taken a bigger (but small size coffee can) and set that aside and cut the tops and bottoms off of a bunch of coke cans so you can have super thin aluminum, then arrange the coke cans aluminum into a heat sink pattern where you have tons of coke can fins. Then pour a small thin layer of molten aluminum into the coffee can while the bottom of the can is submerged in water, then immediately set your complete heat sink made from cut up soda cans into the layer of molten aluminum at the bottom of the coffee can and whalla, you have a heat sink, you can cut holes at the bottom of the coffee can to vent the air and set a fan on top, or if your a real badass cut holes at the bottom of the coffee can, put the lid back on the can and rig a vacuum hose to suck air from the top, and you will have a reverse badass heatsink with super thin and abundant walls for dissipation, plus this way you can make the base very thin so heat can travel through it and up the soda can aluminum quickly and out the vacuum hose.
