FAQ About Electronics Cabinet

What temperature should I keep my electronics cabinet/closet below?

This depends on the equipment you have, but the general rule of thumb is you don’t want the interior ambient temperature to every get above 100 degrees Fahrenheit.  Some consider 90 degrees to be the max, and if you can keep the temperature in this range that is great, but our feeling is never let the temperature exceed 100 degrees Fahrenheit. 
Check with Component manufacture for their suggested maximum temperatures.

Is the Pre-set Thermal Controller OK, or should I upgrade to the programmable LED controller?

The pre-set controller is fine for a lot of applications.  The fans go on at 86-88 and off at 80-81 degrees, and this is a good temperature range.  Sometimes in warmer climates the fans may tend to stay on in the warmer months.  The LED controller allows you to program when the fans go on, and off, and in the above situation you can program a slightly higher on/off range.  The LED controller also gives you a constant read-out of what the ambient temperature of your cabinet is, which is helpful in determining if your cooling solution is doing its job.
