Quieter PLZ!!

Been using the PSU setup that I built a whyle back for my PL6 charger, this weekend I pushed her, charging 4 6s packs at 10 amp each, she made some heat. Sometimes I push it some times I don’t When I’m not pushing it the fans are running slow. when I’m pushing them harder, I can “NOW” change the fan speed to faster to keep the psu’s cooler..

Edit.. Added Movie !
