Should my Hotend fan be on all the time?

As a 3D printing enthusiast, you might wonder whether your Hotend fan should be on all the time, or if you can get away with turning it off at times. The answer to that depends on which fan you are referring to, as there are two fans that run on your hotend – one for the part cooling and another for the heatsink cooling.

The fan responsible for cooling the heatsink should always be on. This is because the filament in the heat sink might cool down and lead to a bad clog. Imagine your Hotend as the heart of your 3D printer, and the heatsink as the lung that helps regulate the printer’s temperature. Just like how the lungs play an important role in keeping the body working efficiently, the heatsink fan ensures that your printer’s Hotend stays at a consistent temperature throughout the printing process.

On the other hand, the part cooling fan is responsible for cooling the print as it’s being made, preventing it from melting or deforming. However, having this fan on all the time isn’t necessary. In fact, some prints may actually require the fan to be turned off or at lower speeds for better results.

In conclusion, it’s important to understand the role of both fans on your Hotend. While the heatsink fan should always be on, the part cooling fan may or may not need to be on depending on the printing job you’re working on. Make sure to do your research and adjust your printer’s settings accordingly to achieve the best possible results.

Creality CR-10 cooling fans offer several advantages that can lead to better 3D printing results. Here are some of the benefits:

  • Better printing quality – Cooling fans help reduce the risk of defects like stringing and blobbing, which can result in smoother and more precise prints.
