Ok, thank you very much! Isn't it surprising for a Seasonic (S12, first version rated 500W) ?

Each are 4412 F/2GLL, rated 60mA/1200rpm at 12V and support a range from 7V to 14V. Yes, they are in parallel (not the speed signal). I have set the pump to provide 72% / 8.7V (which make the fans running approximatively at 930 rpm), in manual mode since I have no choice du to the advanced version.
