Yup, you are 100% correct, although I can measure the output voltage in the stock controller. However, now I'm learning to use the o-scope and was able to see the PWM waves (this is still the stock controller - apparently clean waves) Then I went to measure the PWM from the mosfet module in...

Hey! First of all thanks for all the great answers and support you've been giving. For context, my fan is a Cloudline S6 bought last year. Before starting this project, I tried to debug the stock wired speed controller (image), by sending +10V through its USB connection (4 pin - like the one...

Hey, thanks for replying! So, I have a "good" osciloscope, but still in the learning curve of it and all ESP / Electronics stuff. I'll dig out how can I measure that frequency. I was asking because I could easily measure the different voltages with the original controller (signal wire + / GND...

Hey all, this is a very long shot as this post is kinda old. But I wanted to ask 2 things: 1 - How can test test that the mosfet output voltage is proportional to the fan speed? I was able to check that with a multimeter in the original manual controller, but I just can't check the output of...
