Sunon 12V 4010 Silent Axial Fan - 15.7dBA Vapo-Bearing Fan

When looking at a whole 3D Printer in action, it’s easy to be awestruck bythemany little moving parts, all of which work together to produce resultsthatnone of the individual parts could achieve alone. And what always amazesus ishow each and every single part plays a vital role in the success of thewholemachine, and this even so for the fans that help to move heat andkeepsensitive parts within safe operating temperatures.

With that being said, it’s unfortunate that fans, despite being critical tothemechanical health and safety of 3D Printers, are often some of theloudestcomponents on the machines. Additionally (in a similar way to humans)thesefans tend to get louder with age, and it’s never nice to have a fanmoaningand complaining all day – especially when you’re trying to sleep whileyourmachine is bringing your creations to life.

This is why we’ve been on a mission lately to get quieter fans likethesebeautiful Sunon Original 12V 4010 Silent Axial Fans, which have an ultra-lownoise rating of just 15.7dBA due to the clever MagLev Vapo-Bearing thatSunonis so well-known for. In fact, to give you some perspective on just howquietthese Cooling fans are compared to typical fans, the 15.7dBA noiseratingmeans that this fan is REALLY quiet, with the loudness fallingsomewherebetween the loudness of a pin dropping, and the loudness of leavesrustlingfrom the wind.

Finally, we’ve really enjoyed equipping all of our 3D Printers at homewiththese beautifully quiet fans, and complementing them with SilentStepperDrivers too. It has made a world of a difference in the overallloudness ofthe machine, and as long as we are willing to slow down themechanical motionsof the machine during prints, we all now enjoy near-absolutesilence, evenwhile bringing our obscure and wonderful creations to life.

Helpful Notes for Installing Your New Sunon 4010 Silent Axial Fan:

Whilst many experienced Makers would consider the installation process ofacooling fan to be relatively simple, installing fans on Hobbyist 3DPrintersis unfortunately not as simple as it should be. Fortunately, however,we’veprepared these handy notes on this process, which should help you getyour faninstalled perfectly, and without any unexpected damage or hassles.They are asfollows:

• Check Your Polarities – Because many of the hobbyist fans and 3D Printers available to Makers are typically supplied by different manufacturers from all over the world, the first step that you should take is to check the polarity of the fan with a simple multimeter. This simple and relatively quick polarity check will ensure that you don’t break your new fan (or potentially worse) the moment you turn on the power.
• Wiring Colours May Not Always Match – Don’t simply rely on colours that many of these fans are provided with, because they may not always have the same wiring colours as other fans with the exact same or similar specifications. Additionally, we’ve found that some 3D Printers may also have different wiring, which can sometimes even depend on the batch within the same series. As such, double-check the polarity and markings on the related boards as well, so that you don’t end up running your fan backwards or causing unexpected damage before you even get a chance to use the fan.
• Matching Your Mounting Points – Given the fact that so many new models of 3D Printers come out each year, some machines might have slightly different mounting points. Fortunately though, this is one of the easiest problems to fix, and in addition to simply printing yourself a mounting unit to perfectly fit your fan, we have also provided a guide below that explains how you may be able to solve this problem with a simple pocket knife and a few minutes of time.
