Ender 3 V3 Se Dual Fan 4010 Cooling

The project aimed to enhance the performance of the part cooling system for the Ender 3 V3 SE 3D printer, which had limited efficiency due to the original fan assembly consisting of a single 4010 24V fan. This system proved insufficient to ensure proper cooling of the material during printing, especially for models with fine details, sharp angles, and temperature-sensitive tips.

To solve the problem, a new system was developed and implemented using two 12V fans wired in series, maintaining electrical compatibility with the printer's original 24V circuit. This configuration provided greater airflow and better distribution of the cooling flow over the print area, resulting in more precise layers, better surface finish, and reduced thermal deformations.

In addition to replacing the fans, adjustments were made to the mounting bracket and airflow direction, ensuring more uniform and efficient cooling. The project resulted in a significant improvement in print quality, maintaining the electrical and thermal stability of the system without compromising the integrity of the printer's original components.
