Hi! I am very interested in this project; however, can you share more details on why we should not connect the 120mm fan on the existing port? Is it mostly due to the power ratings or something else?
@Chedomir_D_1207095 The original fan header can only support 2.4W of power to the connected fan. A 120mm blower fan at minimum consumes 12W. That is 5x the limit and will destroy the power delivery circuitry based on what I can see from reverse engineering the motherboard and inspecting components.
You need to power the blower fan without using power directly from the motherboard. I am still working on the wiring guide and diagrams (I did the original wiring months ago and lost the schematic). I should have the guide up by this weekend once I triple check and validate everything.
I love the idea of your system, mostly because of the ability to use a carbon filter with more pressure and the higher airflow through the small hole of the original fan. As a bonus, the noise should be lower too. Please upload the schematics for the wiring. I'm eagerly awaiting them.
