EJT5OirM

Fan mounting panel

Overview

The circuit has two systems: 1. A direct connection to the fan, which blows air as soon as the power is on. This is manually controlled using jumpers. 2. A temperature control system using a 555 timer to reach or exceed a set temperature (50 degrees Celsius) to activate the fan. The first version used some surface-mount components, but as shown in the soldering diagram, saving space didn't seem very meaningful, so a second adjustment was made, increasing the reserved area for the fan connector, etc., addressing the design flaws of the first version. It can now be directly PCB fabricated.
