Yes, because for heat exchange you need to aboid laminar flow and encourage turbulent flow to prevent border layers and maximize the Ξt [in Β°C] between intake and exhaust flow and thus increasing the heat efficiency.
Given the limitations of a finite-sized heatsink that needs to fit into an ATX case with a finite-sized CPU heatspreader and finite-sized heatpipes, #Noctua's NH-P1 basically is peak efficiency for a passive, fanless heatsink.
OFC when you have a forced, turbulent airflow you can go way closer in terms of fin stack, as you can see with the NH-D15.
As for @N33R's original #shitpost: That "improved" design can't be realidtically manufactured and most mono-material #PassiveCooling heatsinks for electronics like amplifiers also rely on the thermal mass of the heatsink to carry away heat.
#Yamaha for example in their #amplifiers and stereo systems did optimize passive heat transfer by having widely spaced, mounted-on sheetmetal fins that attached to a big aluminium heatsink with vertical fins to increase heat transfer surface area
In some models these did literally fill out most of the chassis volume and could thus generste quite a "chimney effect", mandating ventilation openings on the sides and top to be kept clear.
These innovations are driving the tech industry toward a more sustainable future. As demand for efficiency grows, so will the need for cutting-edge cooling solutions that reduce energy use and environmental impact. The future of tech is not just about powerβitβs about smart cooling! π±

Using a flagpole was much easier than previous methods, but the aluminum flagpole is kinda bendy. I connected some string from the window in the middle to take some weight off the pole, so hopefully it'll hold through summer. I also taped around the edges, so the tarp should catch less wind in general.
It's that time of year again when I add reflective covering to the back of my house. Last year I got a big tarp that reflects 99% and attached it with twine to a window on one side and the gutter on the other. That worked well through the summer but pulled my gutter off in early fall during a storm. This year I'll be using the same tarp, but I've ordered a 12 ft flag pole. If it works well, I might consider putting up a second tarp with two flag poles on the other side.
How are #NaturalDisaster-resistant design elements integrated into #Solarpunk buildings?
Publication date: 2023-09-02
"In Solarpunk buildings, natural disaster-resistant design elements are integrated through a combination of passive and active design strategies. Here are a few ways in which these elements can be incorporated:
1. Site selection and orientation: Solarpunk buildings are typically situated in areas that are less susceptible to natural disasters like #floods, #earthquakes, or #tsunamis. Careful evaluation of the site's history and potential risks helps in choosing locations that are more resilient. Additionally, the building orientation can be optimized to maximize #NaturalLight and minimize exposure to prevailing #winds or #storms.
2. Structural reinforcements: Solarpunk buildings embrace resilient construction techniques to withstand natural disasters. This may include reinforced foundations, earthquake-resistant designs, hurricane-resistant materials, and robust structural systems that can withstand high winds, seismic activity, or even #ExtremeWeather events.
3. #GreenRoofs and #RainwaterHarvesting: Green roofs, which incorporate vegetation on the rooftop, offer several benefits when it comes to natural disaster resilience. They can help mitigate stormwater runoff, reducing the strain on existing drainage systems during heavy rainfalls or floods. Additionally, rainwater harvesting systems can be implemented to collect and store rainwater for future use, serving as an alternative water source during emergencies.
4. Passive climate control: Solarpunk design emphasizes #PassiveCooling and heating strategies to reduce energy consumption and reliance on mechanical systems. Natural ventilation through well-placed windows, louvers, or #RoofVents can help regulate indoor temperatures. By not relying heavily on air conditioning units, Solarpunk buildings can maintain habitability even during power outages caused by natural disasters.
5. #RenewableEnergy systems: Solarpunk buildings integrate renewable energy systems like solar panels or wind turbines to generate electricity on-site. This reduces dependence on centralized energy grids, making the building more self-sufficient and resilient in the face of power disruptions caused by natural disasters. Battery storage systems can also be incorporated to store excess energy and provide backup power during emergencies.
6. Water management and flood-resistance: Solarpunk buildings employ strategies such as permeable paving, #RainGardens, and water retention ponds to manage stormwater. These features help minimize the risk of flooding and prevent damage caused by heavy rains or #ExtremeWeather events.
"By combining these design elements, Solarpunk buildings aim to create sustainable and resilient structures that can better withstand the challenges posed by natural disasters."
