The HF-125 is our new high frequency controller that operates at 7000 cycles per second. Some fan companies want their fans to run at his frequency. It will also stop any fan buzz.

Electromagnetic interference aka "EMI"
This invisible problem has effected audio equipment, ignition systems, fuel injection systems, and even alternators. The wire from the controller to your fan is emitting this EMI invisible noise. The best way to deal with this is to shield the wire from the controller to your fan. See our MORE/PDF on this EMI cure.
We received this email from Frank on his alternator EMI problem:
"Its hard to count the number of people who insisted that either the alternator or your controller was defective. No description of how or why, just EMI can't do that!
If I ever do this again, I'm buying shielded wire to start with!"
Before you purchase that brand X controller, check their DC current rating and history of failures! The Auto Cool Guy starts at 55 amps - to a monster 200 amp unit!
