SuperDome: The Ultimate 15-Fan Noctua Cooler That Drops CPU Temps by 20°C

For PC enthusiasts concerned about high CPU temperatures during demanding tasks like gaming or heavy software usage, this is an interesting development. While many prioritize performance components like CPUs, GPUs, and RAM, other parts of a PC build often receive less attention. This can include basic motherboards, entry-level SSDs, stock CPU coolers, or very inexpensive aftermarket options. Many users even settle for the stock case fans that come with their chassis. However, one YouTuber has taken cooling to an extreme with the creation of SuperDome, an astonishingly large assembly of Noctua fans.

Achieving optimal PC temperatures typically involves a robust CPU cooler, whether air or liquid. Crucially, effective cooling also depends on fans that ensure constant airflow in and out of the case. Without adequate circulation, hot air can become trapped, hindering temperature reduction. While standard PC builds utilize 120mm or 140mm fans, projects like the 'Fanhattan Project' showcase more unconventional approaches, such as combining 15 mini Noctua 30mm fans to create a unique, albeit not overwhelmingly effective, cooling unit.

SuperDome: Major Hardware's Latest Creation is a True Beast with 15 Noctua NF-A12x25 Fans, Sized Like a PC Case

The Fanhattan Project, developed by Major Hardware last month, showed promise but offered only a marginal performance improvement over a standard 120mm Noctua fan. More significantly, it generated a substantial 73 dB of noise, indicating that the concept of clustering many mini-fans wasn't ideal. Undeterred, Major Hardware has now unveiled its larger successor, the 'SuperDome,' which integrates 15 Noctua NF-A12 120mm fans. This design essentially scales up the previous concept to a much grander size, to the extent that it occupies the same space as the side panel of their PC case.

The accompanying video reveals the sheer scale of this fan assembly. When attached directly to the side of the PC case, it moves an immense volume of air. Despite the system utilizing liquid cooling for its Ryzen 9 5950X, temperatures under stress reached 86-87°C. However, with the SuperDome installed as a side panel fan, temperatures dropped by an impressive 20°C, settling at 66-67°C under the same load conditions.

Mounted on the Case Side Panel, Temperatures Drop by 20°C with Minimal Noise and Only 28W Power Consumption

Beyond its impressive size, concerns about power consumption might arise. However, the SuperDome offers a pleasant surprise. Despite utilizing 15 fans operating simultaneously, its total power draw of 28W is remarkably modest, especially considering that a single Noctua NF-A12 fan consumes 6.1W. This efficiency is achieved because the SuperDome's fans are not operating at their maximum PWM speed. While precise noise comparisons weren't detailed, the YouTuber notes that it is significantly quieter than their previous mini-Noctua project.

The visual difference between the previous and current projects is striking. The most notable aspect remains the size, and the absence of protective filters or grilles on any of the fans, posing a potential risk to both the fans and the user. However, it's likely this is more of an experimental project to explore the potential of such designs rather than a daily-use solution.
