Your New Favorite F5 Tornado Fan D4s Jp Edition Holiday Edition [w2eRmoSh]

Each fan is specifically positioned to force air down the sides of the amplifier’s heatsink forcefully cooling the hottest part. These are one of the most powerful amplifier cooling fans in the industry period.

This isn’t your basic on/off amplifier cooling fan. It utilizes the latest speed control technology called pulse width modulation (PWM) so if you want quieter fans just install a common PWM controller, sold separately, and turn the speed down.

Fan can be controlled by a basic on off switch or a thermal controled fan switch
