Hi, I made an amp cooler for two amps in my truck. It utilizes 4 computer case fans (Cooler Master Sleeve Bearing 120mm silent fans). After hooking up fans power wires to the head units remote wire and fans ground wires to amps ground the fans turn on as they should when the head unit is powered on. But the fans are generating noise through my speakers. How do I cancel the noise from the fans? I'll attach pictures of the cooler below. I tested it out and if I unhook two of the fans from either amp there is still noise generated. Any ideas?
