12V 4020 Axial Fan

While we often take fans for granted due to their widespread popularity in all kinds of appliances, toys and other goodies, they are actually quite marvellous inventions, capable of taking electricity and converting it into mechanical rotation to blow air and provide active cooling for Electronics, entire machines and even humans. For 3D Printers, a good quality fan is crucial for it to function because without it, problems like heat creep will certainly ruin our print quality. Since fans are so vital and they are typically designed to work non-stop causing them to wear down faster, it’s not surprising we recommend our amazing Maker customers keep a few spare replacement fans, like this 12V 4020 Axial Fan.

These 12V 4020 Axial Fan are compatible with a lot of the standard hot ends found with 3D Printers that utilise 40x40mm fans. Axial Cooling Fans work by sucking air into one side and blowing air out the other. This design, along with the shape of its propellers, mean a relatively low pressure and optimal performance. This fan is 12V DC, which makes it an ideal fit for Creality’s 12V 3D Printers like the Creality CR-10S and other CR-10 Series printers. Effective cooling fans help to harden the printed plastics quickly, which reduces warping and sagging, resulting in far better print quality for PLA, or offering strange and sometimes desirable effects with other polymers too.

If you’re looking for effective cooling for your 3D Printer, but are looking for different styles or voltages, be sure to look at our 3D Printer Fans category to find the ideal model to cater to your needs.

 Helpful Notes for Installing The 12V 4020 Axial Fan:

Whilst many experienced Makers would consider the installation process of a cooling fan to be relatively simple, installing fans on hobbyist 3D Printers and other equipment 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 without any unexpected damage or hassles.

• Check Your Polarities – Although cooling fans can typically work both forwards and backwards without problem, it’s important to ensure that your fan is connected in the right way so that the cooling is working just like it should. As such, it’s a good idea to test your fan before committing to permanent connections, and this can be done by applying power and simply looking (or feeling) which way the fan is blowing. This will ensure that, if your fan is meant to blow air forward onto some electronics or into an enclosure, that it’s not actually sucking air in the opposite direction.
• 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.

Our team of engineers, consultants and specialists have years of combined experience within the world of mechanics, robotics, electronics and programming, which allows us to build specialised products targeted at catering to the real needs of our consumers.

We understand that a good product is not only focused on quality, but also on affordability and accessibility, which is why we manufacture our own in-house products that aim to meet the ever-expanding needs of our customers. One such example is the Prusa i3 3D Printer, which we have improved upon numerous times with specialised extruder designs, laser-cut enclosures and even accessories like spool holders – To provide customers with the type of consistent quality that we would like to experience from every brand, both local and international.

Our in-house products also come with the added benefit of ultimate customer support, because nobody knows our products like we do, allowing us to offer the very best in terms of customer support for building, maintaining, repairing or simply enjoying our range of DIYElectronics in-house products.
