“All
ML fans offer a huge PWM range, giving users total control over how their fans
perform. Value silence above all else? At their lowest speed of 400 RPM, the ML
Series will push more airflow at near silent 16 dBA (decibel A-weighting)”
Corsair comments on
their website about the ML Series Cooling fans
Do
you like Building PC's, sound systems or anything that requires a lot of
cooling?
Then
the Corsair ML Series has the fans that will get the job done as detailed in
the article “Corsair
Intros New Family Of Lit Case Fans, The ML Series”,
published July 11, 2016, By Kevin Parrish, DigitalTrends.
There
are ten (10) fans in the series, ranging in size from 120mm and 140mm as
follows:
1. ML
Basic (x2)
2. ML
Pro (x2)
3. ML
Pro LED (x6)
Fans
for cooling computers are nothing special on my blog, as I've already looked at
3M's Fluorinert FC-72 cooling systems developed by University of Alabama in
Huntsville as detailed in my blog article
entitled “UAH
Graduate Students use 3M's Fluorinert FC-72 in Passive Cooling System – Gaming
Rigs and Data Centres Noiseless Cooling Systems upgrade”.
What's
special here is that these fans use Corsair’s new Magnetic Levitation Bearing
technology.
By
no means is this a new idea as many products feature magnetic levitation, mostly
as a clever gimmick, such as the Mars by Crazybaby Levitating Bluetooth Speaker
as described in my MICO
Wars
blog article entitled “Mars
by Crazybaby Levitating Bluetooth Speaker Levitation Produces good vibration
free sound”.
Combined
with custom rotor design, they run quieter and faster, resulting in noiseless
cooling under any load. So how exactly does this work?
Corsair's ML Series
Magnetic Levitation Bearing Technology - Magnetic levitation and rotating
electromagnets in action
Corsair's
Magnetic Levitation Bearing technology reminds me of a blog article I did on
the idea of a fan floating in a magnetic field as detailed in my blog article
entitled “Global
Warming and the Quest for Efficient Cooling – From Bladeless Fans to Blade
Runner”.
Albeit
their fans require an open standard 4-pin fan connector, you can splice this
open and connect it to the required 5 VDC power supply to cool whatever you
want. Take a moment to admire their impressive performance specs thanks to
Corsair’s new Magnetic Levitation Bearing technology:
These
performance specs are possible thanks to the face that the fans levitate in a
magnetic field like a motor, with rotation being done by an electromagnet at
the edge of the fan housing as shown in the image below.
This
circular electromagnet changes polarity rapidly pulling and pushing the fan in
a manner similar to a Maglev train as explained in my blog article
entitled “JR
Tokai's Chuo Shinkansen sets World Record of 603 km-h - How Maglev Train
travels Tokyo to Nagoya in 40 minutes and Why HyperLoop is faster”.
But
what had me interested is the fact that the fan floats on a frictionless
cushion of electromagnets, making it possible to power this fan by using the
very rotation of the fan to create its own power in a kind of perpetual motion
like loop. Combined with Solar Power, a larger version of Corsair's Magnetic
Levitation Bearing technology in a Fan can be used to make super quiet Solar
Powered Extractors or even Air conditioning units!
You
can still purchase Corsair's ML Series based on their new Magnetic Levitation
Bearing technology. But if you're a true tinkerer, you can
build a levitating fan yourself once you understand the concept of magnetic
levitation and rotating electromagnets!
