While it's not as easy as changing a CPU cooler, it definitely works more effectively than you can imagine.
Major Hardware Demonstrates "Superdome" Capabilities in CPU Cooling by Deploying 15 Fan Arrangement on His Chassis
Enthusiasts do weird experiments, but they sometimes do work. Achieving high thermal performance is something most PC builders are after and from traditional air cooling to custom liquid cooling loops, enthusiasts have tried many, but not all. The YouTuber Major Hardware thought out of the box, and made something that few would have imagined.
The YouTuber wanted to make a dome of over a dozen chassis fans, particularly from Noctua, which are well-known for high cooling performance and silent operation. Thankfully, Noctua agreed to send him 15 Noctua NF-A12 fans which are one of the best cooling fans available. With a 3D-printed dome, the YouTuber deployed all 15 fans on it, which required careful planning.
The total power consumption on the silent or normal mode remained under 30W, which isn't much, but the impact of the Noctua Fan "Superdome" was quite apparent. Major Hardware first tested his rig with the default glass panel on his chassis. The temperature for the AMD Ryzen 9 5950X remained around 86-87°C as per Ryzen Master's reading. Keep in mind that the rig already had a custom liquid loop installed that performs way better than air coolers and conventional AIOs.
After replacing the side panel with the Superdome, he tested again with a couple of games and saw a dramatic drop in the CPU temperatures. Unlike previously, the Ryzen 9 5950X was running at just 66-67°C, which is a 20°C drop in temperature. A 20°C difference is quite huge, which is usually not achievable unless you do some crazy DIY cooling. Last time we saw a 20°C temperature drop was when the Thermal Grizzly Deltamate was installed on the ROG Astral RTX 5080, which is one of the finest DIY coolers made for a high-end GPU.
Not only was the YouTuber able to reduce temperatures by a significant margin, but noise levels also remained very low. He didn't try the high-performance fan mode for the Superdome, otherwise, the temperatures would have dropped even further. However, this was unnecessary particularly when the 20°C is already adequate and increasing the fan speed would result in noticeable increase in noise.
