When looking at a whole 3D Printer in action, it’s easy to be awestruck by the many little moving parts, all of which work together to produce results that none of the individual parts could achieve alone. And what always amazes us is how each and every single part plays a vital role in the success of the whole machine, and this even so for the fans that help to move heat and keep sensitive parts within safe operating temperatures.

These Sunon High-Speed Blower Fans are designed to provide high airflow and effective cooling, and are primarily stocked for cooling PLA prints in high-speed 3D Printers. However, while we prefer to keep our 3D Printers going at a relatively low speed in order to get the best possible quality, we still love to use these fans as they ensure that the PLA hardens almost instantly after leaving the nozzle, resulting in beautiful, strong bridging, less webbing and stringing, as well as stronger support from the lower layers as the layers are being printed above.

These Sunon 12V 5015 Blower Fans are some of the best cooling fans that we’ve ever enjoyed stocking, as the High Speed Vapo-Bearing ensures not only effective cooling, but also a reasonably low noise level that is rated at just above the loudness of a standard desktop computer. However, if you’re looking for REALLY quiet fans, be sure to take a look at our Cooling Fans range, and check out the other fans from Sunon, which are designed specifically to offer ultra-quiet operations while still offering effective cooling.

Please Note: Because of this fan’s large size, it may require an aftermarket (or 3D Printed) mounting plate in order to effectively mount onto the sides of typical hotend assemblies.

Helpful Notes for Installing Your New Sunon 5015 High-Speed Blower Fan:

Whilst many experienced Makers would consider the installation process of a cooling fan to be relatively simple, installing fans on hobbyist 3D Printers is unfortunately not as simple as it should be. Fortunately though, we’ve prepared these handy notes on this process, which should help you get your fan installed perfectly, and without any unexpected damage or hassles. They are as follows:

  • 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.


Additional Resources:

  • Finally, if you find that the spare fan you purchase is just not quite the right size on your Creality machine, this Creality Fan Fitting Guide from the highly reputable TH3D brand offers some great insights into how you can remedy this with minimal effort and a simple pocket knife.
