"But, of course, the SSD gets quite hot during operation so I used one of the heatsinks from the PC and another made from part of carpentry square and some thermal adhesive tape to keep things cool." Instead of this i would suggest a fan. Even small ones create much more airflow than needed when please next to a device.

A block of metal is great heatsink, and a long ruler like that is both thermally conductive and has decent surface area to radiate heat away. More importantly, a fan is not a carpentry tool. Now, one could use a drill, shop vac, or circular saw to generate wind, but they'd be much less energy efficient than the passive radiator.

  I didn't understand the blog post as a challenge to only use carpentry tools but think he used what was available in his shop. (Most carpenter wouldn't have thermal adhesive tape or a thermal camera either ;-)

  For long term applications I much prefer passive cooling (AKA a hunk of metal.) I have one Raspberry Pi 4B in a case with a small heat sink on the processor and a small fan driven from the GPIO pins. It keeps the processor within limits even when overclocked and heavily loaded. Some day the fan will stop working and the processor will overheat (under heavy load) and throttle to prevent self destruction. I have two Compute Modules (CM4s) and found a passive heat sink that is finned aluminum that covers the entire module. There is no fan to fail. I can overclock the CM4 to 2 GHz and load it for stress testing and it remains well within limits. One of these is equipped with an NVME SSD and I was surprised to see it reach excessive temperatures under heavy loads despite the PCIe x1 connection on the Pi. I got a "hunk of copper" NVME cooler, cut it to fit a 2230 NVME and it keeps the NVME SSD within reasonable limits.

  Circular saws sure do produce a surprising amount of wind, but the thought of using one for cooling is horribly terrifying.

  Doesn't that really depend on the metal? E.g. copper is a great thermal conductor while stainless steel a really poor one.

    Combination square blades are normally plain carbon steel, not stainless. Actually, almost nothing in a wood shop is stainless because it sharpens poorly[0] compared to O1, A2, or any of the other tool steels you'll find in a wood shop. [0] Yes, I realize that stainless and carbon steel are two whole classes of alloys, all with different characteristics. Based on my experiences with kitchen knives, I'll stand by my claim that at least the common ones sharpen poorly compared to the common carbon steel alloys.

    Of course it depends on the metal! But for a hackjob like this, I'm betting it was run without any thermal management first, and then with the ruler as the first thing at hand... that the effort succeeded at that stage suggests that the alloy is sufficient.

  I was going to repurpose some small old tower fans for some windows in "vent mode" where the window is open slightly but has a latch to lock in in place for security.

  i AM LITERALLY IN TEARS I finally know what my grandfather was doing. He was repenting for his role. My other grandfather worked on the Enola Gay... FUCK - I have a nuclear curse on my family. I am serious - this is a wow to me, as this curse eluded me for all my life

    ...You should really check on a few things before getting too carried away. After all, nuclear material doesn't just end up in milk. You're implying an extra step of adulterating milk that was otherwise clean. ...Also, you're assuming that this adulteration continued throughout the course of your grandfather's life, and not just the duration of the (inarguably unethical if conducted as described) research. Regardless though, none of that is your fault. That was him, you're you. Don't take on your shoulders culpability that has no business being there, and just focus on being better. If you do find papers describing the research, however, there are worse ways to handle it than going to the press/Congress to possibly see if you can track down surviving descendants through application of copious amounts of FOIA. Unlike you, the Government absolutely does still hold culpability for any such research it did. That'd be right up there with the Tuskeegee syphilis experiments there. Vaya con dios.

      Its with weird realization at 48 years old I am finally able to understand some of the things that my grandfather was silently telling me. Its not my fault - but I didnt know until I was able to see ;; I have been a "conspiracy theroist" for many years thinking all was golden. My grandfather, now I know - through his gaze - through his eyes "the window to the soul" - He wanted to tell me, but couldnt tell me until I could understand. Now that my grandmother has passed at 100 - I now know. I now know. My fathers father built hanford. My mothers father was a weapons person on the Enola Gay. I now know the true extent of my nuclear curse. I need some time to process.
