Hello
@Leveraged Sellout , Dilan from Two notes here
I'll try to be as complete as possible regarding the fan of the Captor X.
As you have been informed, the fan is passive and is powered by the incoming signal. The fan is triggered by the signal - when the signal reaches a certain level the fan will kick in, whatever the temperature inside the unit. The point at which the fan kicks in is completely independent of the level of the temperature inside the unit.
We conducted plenty of tests when we were developping the Captor X, including playing loud amps over 24 hours through the Captor X with the fan spinning - we recorded no issue during these tests.
The Captor X is equipped with a security thermal load that is activated if the unit goes in overheat (due to a load box failure, or a fan failure for example).
You can use the Captor X with the fan kicking in regularly, even at all times - you need to monitor if the Captor X is getting too hot, this is the most important parameter.
