Cooling Fans causing electrical noise
I'm experiencing significant electrical noise from my amp rack’s cooling fans. The addition of a relay setup only made it worse. Here are a few details of my setup:
I’m currently running the fan power switch from the amp’s turn-on-lead to a 5v power regulator to the Stinger SFC temp switch. (seen here) The fans run at half power when the amps are on and 100% above 90 degrees.

Ground is separate from the amplifiers.
How can I get rid of the noise?
