Hi!
In my watercooled system I noticed that most loud place - PSU, by default Super Flower has very weird logic for fan mode, even in ECO fan will spin up and down each few minutes even without load. I wrote message to support, but no luck, they replied that fan logic can not be change, even would be better to have static RPM for always, but it doesn`t work (work with the same way as ECO). And while playing in games I can hear 2 thing: coil-whine from RTX4090 and very loud fan from PSU.
All RPM curve mode depending on temps in PSU, but I did not find temp sensor, so maybe it installed from manufacturers in such weird place that very fast hit each minute?!..
So, almost new psu was upgraded:
Stock fan is 130mm, I did not find any replacement, so decided to use my 120mm favorite Noctua NF-A12, but issue that fan is PWM, but I am engineer![Smile :) :)](https://tpucdn.com/forums/data/assets/smilies/smile-v1.gif)
Decided do not put again this plastic cover, because new fan will not blowing air to mesh.
And I am very happy with result
Connected PWM cable to Octo controller and setup curve, but before created virtual sensor that getting wattage from cpu + gpu and will use formula for transfer watt to %.
So, I have in "office work" 400-500 RPM on PSU and my Mora radiator and during playing in Cyberpunk (12600KF+RTX4090) my system load will be 550W and 700-800RPM in PSU, very quiet and no weird logic for fan curve as it used for Super Flower.
