Ok, I understand changing your whole standardized setup for testing passive coolers maybe not a way, BUT how about simply extend you standardized cooler tests for temperatures on combination cpu idle + manually set 0 RPM, I would LOVE to know what cooler to actually get for next build so that I can run passive for idle/office work. Who cares how low the temp can get for some of these coolers if that means 35+ db on staring to excel spreadsheets or similar. Start making charts for 1) cpu idle 2) cpu load 3) cpu idle + 0RPM.
E.g. as professional (casual gamer, but still have 64G of ram for work and other crap, you get the point) I have a build at home that was specifically built with fanless operation most of the time: seasonic fanless PSU and CPU and GPU fans configured to be 0 RPM in idle / casual office work and only start spinning (even that limited to 600-800 RPM) on 80c mark when load comes. That is achievable with of the shelf components and no crazy whole case is a heat spreader . I do have 55-60c on CPU in idle this way, but why the hell would I care.

well,... i guess passive cooling would be interessting for me, especially with upcoming cpus that are even more power efficent than whats available today. Allways wanted to build a passive cooled system, but the amount of heat that cpus produce makes it a very difficult (If not impossible) thing to do. I guess when 3nm cpus or even 2nm cpus will be on the market, passive cooling could be a nice thing to have.
Correct me if i am wrong, but the smaller the transistors gate gets, the less voltage you need and therefore the less power will be consumed wich results into less heat. If i am correct with this assumption, passive cooling could be right around the corner, to be an interessting choice. (Sry for my englisch, its not my native language.)
The only thing that bothers me a bit is, that a fully passive cooled system wont be possible ever... at least i couldnt see a gpu to be fully passive cooled ever.

When the passive Noctua cooler comes out, could you do a comparison with big air coolers without fans and as a reference a big surface area AIO run passive (or a custom loop with a massive radiator, but with such a long runtime that the water reaches thermal equilibrium)? Or make a passive roundup video that you could use as a reference after the Noctua review comes out. I myself is in the crowd that runs the fans at the lowest setting until the heat rises and I then ramp them up accordingly to the specs of the parts, both air and water-cooled. Silent when idling and noisy when needed. A fan roundup would also have been cool, like the old Anandtech ones, just in video format and with newer fans. One for air coolers, one for water-coolers and maybe one for case fans.

At this point I'm assuming you are looking for things to point out. While the spelling errors are in fact avoidable and show lack of attention to detail. The ram sticks in those slots are clearly on purpose to show possible buyers how RAMs sticks will work under the cooler (occupying slot 1 and 2 instead of just the first) I completely understand why they did that, despite being the wrong way to put the ram, it shows important information for new builders who are not experienced. There's clearly an intention and point it as a mistake is a bit forced on GN part.

lol, i have some old hardware in my 10900KF and 3080 box, and that would be a cooler master 1000W PSU that is virtually sillent, as its passive almost all the time, and a Zalman CNPS10X Extreme , i cant find any info on it, and it would be super cool guys, if you can test that in your testbed, as it would be cool to see if i have to change it anytime soon, i have 33 degrees idle and 87 on a full real load, prime and other heaters , load it until 97 (still outside the Thermal Throttling zone), i cant believe it really :)

Would definitely like to see it tested passively but I don't think testing on your heater would be best way to test. Yes that's best way to compare passive coolers and should be tested that way but id still like to know if case fans would move enough air to keep it cool. Also I'm a bit disappointed in your thoughts on Fuma 2. If you account for everything including cost it's by far the best choice currently. Most people after air cooling aren't looking for biggest headroom. Also would like to see TDP limits tested

I picked up a Scythe Fuma2 about 6 months ago after watching some reviews on here and it does not disappoint! Works so well that I ended up completely switching back to air from AIO's! Has been nothing short of awesome. 3700x idling in mid 30s and gaming in mid 50's. All pbo limits removed! Love these videos! Always the first reviewer I search for when I am interested in a product! You definitely do the most in depth testing!!!! Thank you for the hard work and dedication and looking forward to many more videos!

on the note of the single use plastics:
if theyre using cheap plastic baggies anyway, i'd rather them just come in a single bag unless there are especially small parts or some special consideration. However, i think it's a neat move for more 'premium' products to come with a plastic parts box, that can be used to keep extra parts sorted/ be repurposed for other household bits and bobs.

I've never really understood why people go to so much effort to get a silent CPU cooler. I've never owned a PC where under load you can even hear the CPU or case cooling fans over the noise of the graphics card. Even if I go back to the 90s when passive cooled graphics cards were a thing, back then it was the drives and the power supply that were louder than my CPU cooling solution.

I wonder how well it performs with proper high static pressure fans. At that point you might as well as buy a better cooler with better design but simply out of curiosity someone should test this with 2 Noctua A12x25, Gentle Typhoons or Arctic P12's and see if they are able to overcome the high impedance of this cooler.
