Receiver/Amplifier 12v trigger-controlled cooling fans/enlarged bases/multispeed

Description

12 volt trigger-controlled Dual-Fan Quiet Component Cooling system
This dual-80mm fan unit, with super-quiet Fluid Dynamic bearings, is designed sit on your component's top air vents.
The cooling system includes a 12v trigger module,
which turns the fans on and off, when controlled by your component's 12 volt trigger system.
In addition, you control the speed of the fans, with the multi-voltage power transformer.
Each fan has a special raised air-chamber base, which covers nearly twice the area of a standard fan.
You will feel a steady stream of warm air as
the fans pull the hot out of the top of your component, over the full area of these raised bases.
ABOUT 12v (12 volt) TRIGGERS:
Many modern receivers have this feature, which turns other components or accessories on and off automatically.  It usually consists of a socket (sometimes more than one) on the back of the receiver, into which you plug your 12v control cable.   Normally, when the receiver is on, this cable provides a 12 volt signal to the other component, which tells it to be "On".  When the receiver is off, the 12 volt signal stops, and the other component goes "Off".   Some receivers have a different 12v setup, which allows you to program the operation of the 12v outlet.
IMPORTANT:
My 12v trigger module will turn the fans on and off automatically, whenever 12 volts is applied to the control cable.  When the 12 volts turns off, the fans stop.   Please check your receiver's operation manual, to confirm that your system can provide this 12 volt signal whenever you want the fans to run.

Features
This cooling system has two high-quality, low-noise 80mm fans, with long-lasting and quiet fluid dynamic bearings.  The fans can be separated up to 20" apart.  This allows you to place the fans on two different hot spots on top of your component.
The system includes a 12v trigger module, which turns the fans on and off, using the 12v trigger socket on your receiver
(see note above about operation).  The 12v trigger module comes with a cable which has a 3.5mm (1/8") plug on the end -- the standard for most systems.   If you need a 2.5mm trigger plug adapter, please let me know (there is a small charge).
The fan units have a specially-constructed raised air-chamber base that enlarges the area of air flow, while also sealing air and preventing vibrations.  Each air-chamber base covers over 2 times the area of a standard fan.
Includes a multi-speed power transformer, which plugs into any 120 volt outlet.
You control the speed of the fan, using this multi-speed transformer, which can be set to any one of 6 different speeds.
INTERNATIONAL BUYERS:
The unit's power transformer (supplied with the cooling system), can be switched to either 110/120 volt or 220/240 volt operation.  However, the transformer uses the standard US-style 2-prong plug.
Contact me if you need an adapter plug
(there is no charge)
, and specify one of the three types:  1) NZ/AU  (2 slanted prongs) 2) Euro (2 round prongs), or UK (three large prongs).
Even at medium speeds settings, the fans will replace a volume of air equal to that of most components several times per minute.
All cooling system parts connect together using special heavy-duty Molex quick-connect plugs, which allows the parts to be separated for easy wire-routing.
The system comes completely assembled, with all components installed, wired and ready to go!
Just plug it in, and drop the fans and sensor on top of your receiver.
