With the adjusted fans? Yes it is.

The PSU fan upgrade is really worth it, you immediately lose the whiney sound and it’s much quieter. When starting up the fans do go to 100% for a while which ofcourse causes noise, you can’t stop that. I have it set at constant low power rate and a constant fan speed of about 35% and that’s perfect. A bit of noise, but not more than a dishwasher or something like that. I did set the fans to a fixed speed though: if it fluctuates it’s more annoying imo than a constant low noise :)
