World's Biggest Computer Fan: Corsair 500mm LL RGB Fan

Our most revolutionary test yet is here: Corsair made a 500mm fan, and it's our job to test it. We also tear it down and repair it in this video, because 500mm needs a big motor.

The Corsair 500mm LL RGB fan was, we think, made as a joke -- but it's Corsair, so we're not quite sure. Sometimes it's hard to tell with them. In any event, the fan is about the size of an entire glass side panel for a PC case, and so we thought it'd be fun to do an actual thermal benchmark with it in a fully controlled environment, using our standard case reviews test bench for the thermal testing.

If you have no idea what this thing is, you can see the unveil in Corsair’s original tweet:

Finally, a fan to meet the needs of the 11900k

[kdawg]

Corsair, if you're watching, letting Steve hang on to the fan and play around with it some more is better marketing for you than anything the fan would have been used for originally.

[peace_maybenot]

I'm seeing a strong correlation between the amount of giant 500mm fans produced, and the amount of graphics cards available at a reasonable price

[DaneH]

No joke corsair should actually mass produce these, I'd buy one to use as a box fan

[Thermalions]

Steve: "We hope Corsair forgets about about it and lets us keep it"
Also Steve: Posts video about it on the channel (that Corsair no doubt monitors).

[Neverwinterx]

You missed the great chance of a shot of Steve standing in front of the fan with his glorious hair blowing in the wind.

[biggranny]

Low-key this would be super cool as a box fan.

[erlandjohansen]

This is why nobody's afraid to send even the jankiest of prototypes to GN, they know if it breaks GN will just fix it

[NeonNmesis]

Love how true to life Corsair kept this fan, down to the sticker on the front being imperfectly placed.

[bleepbloopnotabot]

For giggles what you needed was a slow motion montage of this fan blowing through Steve and Patrick's hair like they're supermodels while some funky sounding music is playing.

[qwkimball]

"There's exactly ONE of these in the world."
"Cool. Can I have it?"

[lynxmaster]

The reason for the grinding and all the metal shavings inside the gearbox is the worm gear. It transfers the rotational force in a different direction so it can have way higher torque (which in this case, it needs that torque for that tiny motor to move that massive fan). The downside is that the gear can only move if the motor is moving, making it a very poor choice to use this particular design of gearbox. When the power to the motor us cut off, the worm gear will stop turning and the momentum of the fan will keep spinning, causing the regular gears to grind against the worm gear. That's why its having the grinding issue. Sorry for the rant. Just had to say it since no one in the video did :P

[dapz]

Now someone needs to make a 500mm sized scale model of a delta blowiematron that needs an entire kilowatt of PSU power to function

[alexporter]

That motor uses a worm gear drive, which does not allow for "back driving." This is due to the physical geometry of the gear engagement. My best guess is that the relatively large rotational inertia of the fan blade is able to overcome this by displacing the motor shaft and/or shearing metal from the worm and/or wheel gear. This will never work well as every time the fan is powered down, it is going to cause excessive wear. Unfortunately, a different gearbox is the only fix for this problem.

[tristen]

Ok but how cool would that be to have as a room fan. You got it’s rgb synced with the pc

[MartinzW]

I wish you had the opportunity to perfect the current design:
* Put in at least 10w motor,
* Greased up or rebuilt the gearbox,
* Replaced belts with a single belt.

And then in another episode make it extremer with even more powerful motor and powersupply.

[PotatoSebs]

"Hey dawg can I cool this crappy PC Case?"
"Only with 1 fan."
*Pulls out comically large fan*

[sludgefactory]

Man, call me crazy here but I kinda dig the whole entire side of the case being a giant fan.

[skyvenrazgriz]

GN does no clickbait, the frikn thing is real! Thats why we love em.

[DawnApon]

I will say that the whole side-quest of reconstructing the giant fan made the video that much more entertaining.
