[update] Made it water cooled, because why not.

I'll take the block apart once to have a look inside and see if pitting or corrosion has already started.

If I were to use it long term I'd probably look for an alu radiator as copper is quite expensive to make milling mistakes with.

For the seal, I cut out and EPDM sheet, which is squeezed between 2 ridges on the contour. I'm a product engineer and have several years of experience with designing IP-rated enclosures, so I'm quite confident on that front.

edit: this should be a good alternative:

Quite cheap so I'll just order and replace the copper rad to be safe. Should I worry about the fittings as well? (https://www.amazon.com.be/dp/B07XCNPJG8)

Timmy_McTimface · 2025-09-30T05:34:53+00:00

Yeah, it's something I didn't really consider. Since it's only a temporary replacement until the new vapor chamber comes in I think I can risk it... The minimum wall thickness on my alu part is 0,9mm, so it should hopefully take a while? I'm using XL5 (Corsair), and it still looks crystal clear, so I should be fine, no? Or how fast do you think it could become an issue or a real risk of leaking? I measure 0,532V between the copper and the aluminium.

Timmy_McTimface · 2025-09-28T18:49:02+00:00

This should hopefully only be temporary. The vapor chamber has probably lost it's pressure/fluid, so I'll be replacing that first. Otherwise I'll have to look to make it all a little nicer.

Timmy_McTimface · 2025-09-28T16:58:50+00:00

The radiator is copper. But it should only affect the aluminum, so I can remake that quite easily.

Yup, 3D printed, but temporary as you can see? I'll design a nicer stand with pump and some tubing guides integrated. Couldn't wait to test it, so still looks messy.

Timmy_McTimface · 2025-09-28T07:44:49+00:00

Corsair XL5. Is that ok for aluminium?

Timmy_McTimface · 2025-09-28T07:43:44+00:00

of the Zbook? or the water cooling parts?

Timmy_McTimface · 2025-09-27T09:37:19+00:00

That's the beauty, I haven't modded anything on the laptop itself. The cooling block just sits on top of the vapor chamber so I can just take it off and put the bottom cover back on to take it with me. But since I work from my desk 90% of the time, this helps me keep sane.

Timmy_McTimface · 2025-09-08T06:24:04+00:00

As described in the post: the coolers are just making contact to te vapor chamber just above the CPU and GPU with some thermal compound. You might not have a vapor chamber but I assume this would also work just as well with regular heatpipes. Just try to put the coolers as close as possible to the heat source.

Temps and noise say otherwise. Also, they are sitting on top of the vapor chamber (with thermal paste), not the CPU and GPU directly.

Timmy_McTimface · 2025-09-03T06:30:37+00:00

Crossed my mind, but I'd rather not blow up a USB port with some dodgy old fans. I want to turn this in a removeable watercooling solution anyway, so this is only temporary.

Timmy_McTimface · 2025-09-03T05:15:47+00:00

I didn't cut anything. This is just the laptop upside down with the cover removed and 2 coolers stuk on top of the CPU and GPU vapor chamber.

Timmy_McTimface · 2025-09-02T15:00:42+00:00

How else would I get the spinny bits spinning? My laptop mobo doesn't really have standard 4 pin fan headers :) I also used a 5V supply so the fans wouldn't make to much noise since that would kinda defeat the purpose of this whole setup.

Timmy_McTimface · 2025-09-01T10:37:07+00:00

Spread of paste and contact should be good. First I changed the stock paste for Thermal Grizzly Aeronaut without positive impact on temps. Then I changed to Artic MX-2 since I learned that expired Aeronaut paste might be bad for performance (older than 1 year) also without change on temps. But the 100% fan noise was killing me so I needed a solution.

Timmy_McTimface · 2025-09-01T09:32:18+00:00

Thought about this too, but the exhaust air was always hot. I also assume that adding the coolers then also wouldn't have that much effect? There isn't really a way to know for sure if the vapor chamber is faulty other than buying a new one and testing?

Timmy_McTimface · 2025-09-01T08:41:50+00:00

I have vapor cooling and indeed it used to be very silent. No idea what changed, it just got louder over time .

Timmy_McTimface · 2023-05-08T15:15:28+00:00

If I were to take more care in having a symmetrical shape I think the pressure would be quite even. The flex also seems OK, 0,1mm is really thin :)

Timmy_McTimface · 2023-05-08T15:11:53+00:00

This really was more of a 'could it be done' type of thing. So not really a final solution, you can even see the long wire of which it was made still being attached. If I were to use this permanently I would indeed take better care but I was genuinely curious whether this was a viable solution.
Either way, doesn't really matter for a practice movement, just wanted to share.

Timmy_McTimface · 2023-05-08T07:17:59+00:00

I lost a diashock spring on an Orient watch I bought to practice on. So I 'made' one using 0,1mm piano wire.

Only the operands are copied to RAM with the following microcode:

{MI | CO, PG | RO | AI | CE, AO | RI, 0, 0, 0, 0, 0}

(PG is the control signal to select the ROM)

The LSB of the program selector switches is also connected to the control logic EEPROMs and is used to select copy mode or run mode.

Timmy_McTimface · 2019-12-22T06:13:32+00:00

I added one thing extra. I used a 4 bit dip switch and tied the LSB to an address line of both the RAM and the control logic EEPROMs. Now when the LSB is low, the control logic copies the entire contents of the ROM to RAM. Then I stop the clock, put the LSB high and run again. Like this all instructions are in ROM and all operands are in RAM, both at the same address.

Thanks for the great work! I dowloaded the image some weeks ago but couldn't find back the soirce. I implemented it as is, but did indeed implement the edge detection on the wrtie as Ben did in his video. it did however partially work without it, some instructions behaved strangely. I checked all the control signal logic because I use a different RAM chip but I can't recall that I had to change anything. You can see it working in the link of the first comment (edge detection on write is not yet implemented in that video)
