Subscribe to our newsletter A YouTuber made a giant 'superdome' fan that consists of 15 separate 120mm case fans This 3D-printed project turned out far better than a jokey prototype he previously made In fact, the superdome solution dropped the CPU temperature
by 20C / 68F and wasn't noisy when doing it either If you're a PC
enthusiast, and a fan of fans, as it were, here's a project that's guaranteed to pique your curiosity a giant 'superdome' fan, comprising of a whole bunch of standard 120mm cooling fans, that attaches to the computer as a side
panel.

As spotted on Reddit , YouTuber Major Hardware came up with this idea, which was inspired by commenters on a previous project showcased on his channel.
The idea with that older video was to build ' The Destroyer of CPUs ', a tongue-in-cheek version of a 120mm Noctua case fan. It was a bizarre version of a Noctua NF-A12x25 fan made up of 15 tiny little (30mm) fans, arrayed in a dome design.

Done more for fun than anything, it was impressive that the custom
15-tiny-fan take on a standard case fan performed just the same as the full Noctua 120mm version in terms of the cooling delivered. Actually, it was a smidge better based on Major Hardware's testing, albeit the custom effort was a lot noisier which was the notable wrinkle.

Commenters then suggested building a huge dome made up of actual Noctua NF-A12x25 fans, so that's exactly what Major Hardware did.

Noctua sent the YouTuber 15 of these 120mm fans, and Major Hardware scaled up the previous concept, 3D printing the necessary supporting structure, to produce a big superdome of a fan that essentially slotted on to his Lian Li
PC case as a side panel. You can check out the result below. Building the Superdome: A 15-Fan PC Side Panel - YouTube Watch On Dome and dusted The YouTuber found that the new giant dome design was far more practical than the previous miniature effort which was simply made for a meme. Get daily

Testing how hot the gaming PC got in a Battlefield 6 session showed that beforehand, the CPU temperature reached 86C / 187F (the YouTuber fully admits that the cooling setup isn't optimal here, preferring RGB aesthetics over thermals to an extent remember, the PC has to look the part on YouTube ). However, with the superdome fan in place, the temperature of the Ryzen processor dropped to around 66C / 151F when playing the shooter a big difference of 20C / 36F overall.

Also, unlike the tiny prototype version, this supersized fan didn't make a racket, with Major Hardware observing that it "doesn't make that much noise".

So, were there any drawbacks? Well, the superdome does use a fair bit of power, although at just under 30W, it's not a wattage guzzler. There's also the issue of a lack of dust filters in this implementation, although the YouTuber observes that he's not too worried about that due to the way his
case is set up to exhaust the hot air anyway. What to read next No, its not the latest games console - AtomMan G7 Pro mini PC from Minisforum goes on

Indeed, Major Hardware was very impressed with the giant fan, noting that "it's kind of nuts" how much air the superdome is pushing around, and concluding that: "I might just leave it on my PC as is."

You can make your own version if you wish, as the 3D printer designs (for the Lian Li case) are available (and provided in the details on YouTube),
although the other drawback, mind, is the cost of buying the necessary 15 fans. They are $35 apiece in the US at the time of writing, so you're looking at $525 plus the cost of the other materials for printing and assembly.

Still, you'll end up with quite a 'statement PC' and one that's pretty effectively cooled by all accounts just keep an eye on that dust
accumulation if you go for a giant fan-dome panel for your gaming rig.
