#22It's funny how brands started to copy fifteen years old Gentle Typhoons ten+ years after their launch. It's like some fashion trend, everybody now needs to have their interpretation: Noctua; Scythe; Thermalright; be quiet!; Corsair; XPG; Thermaltake; Akasa; Cooler Master; MSI... and probable more I forgot/have never seen. Sad thing I already typed the biggest players in fan industry, so I wonder if they ever manage to create a design outperforming old one from Nidec, company even not so into pc cooling.

ChaitanyaXPG is not copying GT they have officially partnered to bring those to retail, while others yes have been "inspired" by GTs.

LabRat 891Good catch @Chaitanya. I do not see any power specs other than "12VDC" listed anywhere in Lian Li's literature.



There's not even a max amperage spec on the motor hub's label.
One would be wise to avoid using these on motherboard headers until Lian Li publishes the power specs. It's not impossible that these fans have a very stout 'startup current' and will burn out headers.

I like Lian Li, but 'conveniently forgetting to list specs' is a big red flag for deceptive marketing.


Hardly.
Different materials, different features, and Noctua bothers to actually inform prospective customers of power specifications.
So, no, it's not a clone at all; the Noctua is openly the better fan until we can get full specs and testing reports/reviews.

Chrispy_I'm just happy that the RGBLED fad is finally dying off. After a decade of RGBLED we are no closer to it being a simple, hassle-free commodity; All we seem to have to show for it is a fragmented mess of proprietary spaghetti cabling and hub nightmares, proprietary software with unpatched vulnerabilities/bloatware/telemetry-spyware and feature-creep to the point that PCs actually run measurably slower with some of the worse implementations (assuming they don't cause stuttering or system freezes *COUGH* NZXT)

Can we have more RGBLED-only peripherals please - ideally with a nice and simple internal USB header. That leaves things like fans and heatsinks to get on with doing their actual job rather than pretending to be a Christmas decoration.

Chrispy_Like I said, salty.
The whole RBGLED ecosystem is a mess and I deal with it because I have to, not because I want to.

I can't wait for Microsoft to integrate basic RGBLED control into windows. Getting rid of the malware that is RGBLED software will be one of many important steps to disinfecting the catastrophically toxic and vile RGBLED control software market. OpenRGB is borderline okay, but it's so incomplete and powerless because manufacturers don't pay any attention to it. Microsoft is hard to ignore, if MSI, Corsair, NZXT, Asus et al don't work with Microsoft RGBLED control, there will be hell to pay and much ridicule/grief.

Chrispy_There's no standard way to measure noise levels, so companies can measure however they want to generate just about any values they want. Even independent reviews are no good in isolation as there's a lot of variance in measuring equipment and what frequencies, exactly, it measures and how those frequencies are weighted.

The only valid reviews for me are where the fan in question is tested against a fan (or fans) I have on hand to compare against, or have lots of prior experience with.

bonehead123I think it's high time for FAOSS to step up and push REALLY HARD for the adoption of an open, NON-Proprietary/standard control app that any & all mfgr's can use on any case, fan, rad, GPU etc.. and that works without all the messy issues that are now present in the market...

CammMicrosoft is currently developing this with native control in Windows.

Fucks me if it'll ever come or be any good, but is what it is.

Chrispy_Sometimes they are, and if you read the rest of my post you'd see that the lights that AREN'T on the impeller hinder the fan frame instead.

I'm not trying to belittle you, but unless you're an S.I. like me, I get paid to deal with more RGBLED in a week than you probably see in a decade. I'm salty for good reason.

OberonShow me ONE fan where the LEDs are on the impeller. You may deal with a lot of RGB, but that doesn't mean you know what you're talking about.

Chrispy_Every hub-lit (non LED-ring) fan; The impeller is typically lit by LEDs on the outer edge of the fan-control PCB below the coils of the motor hub, and the plastic impeller is enlarged to include a wider diffusion layer around the fixed magnets. Enlarging the hub to provide a solid volume of translucent plastic for light diffusion increases the rotating mass of the impeller and reduces the swept area of the impeller's rotors.

There are never any LEDs in the impeller itself, that's always just a piece of plastic with a permanent magnet ring in it and the spindle for the bearing, but the impeller does get compromised by the additional mass and physical space that the light-diffusion ring of additional plastic takes up.

Whether it's a lit impeller or a lit frame, it doesn't matter - the impeller is compromised in some way.

OberonSo the LEDs aren't on the impeller. Weird.

OberonThe LEDs aren't on the impeller :laugh:

Chrispy_RGBLED hinders fans. The lights themselves are rotating mass that needs balancing.

Chrispy_Are you being pedantic over wording? The only person who has talked about LEDs on the impeller in this entire thread is you:

You're misquoting me; I said this:

"Lights" are the entire assembly - which is in this case is the PCB for LED power, the LEDs themselves, and the diffuser - in exactly the same way that an incandescent light is more than just the tungsten filament in isolation. To get the desired lit impeller effect people expect in an LED impeller, you need an additional volume of spinning translucent plastic to act as the diffuser - which is all part of the "light". Without it, you'd just get the four single points of light on the hub and the impeller itself would be mostly unlit.

Either way, my point remains the same however you interpret it - there is additional rotating mass in an LED-lit impeller that needs balancing (and robs the impeller of some swept area).

OberonYou're just trying to backtrack to cover a dumb statement and ignoring the obvious counter example I gave you.

Chrispy_Ditto to you, and welcome to the ignore list - I don't need to play these dumb games and I've made my statements very clear.

Nobody who has ever seen an LED fan has seen the LEDs themselves spin. It's blindingly obvious that the spinning effect is just cycling of the individual static LEDs because it's never done that well, the "framerate" is never high enough and even on the best RGBLED implementations I've seen you can still always make out the individual LEDs.

Fry178@Oberon
lol, wut?
having a bigger hub means less fan blade area, means less airflow/pressure, compared to same blade with smaller hub area.

so stating this doesnt effect anything, is completely false.
ofc, if you know what you are talking about...
