Can i use it in a humidor to circulate the air it would be in a timer for one hour everyday

power cycling resets the speed controller. If low speed is adequate for your humidor then yes. Or you can bypass the speed controller and plug.

Is the 102 cfm a combined value, or a per-fan value?

Hi friend! Thank you very much for taking the time to reach out to us with your question! The speed controller voltage range of this cooling fan is 4V to 12V. When the fan is at 4V, it will work at very quiet, the speed could be slower. you can adjust the fan speed freely according to your demands. Thank you for your question! Warm regards, Andrew GDSTIME

Can we use it on the air vent on top of AV receiver/amplifier to cool it? what is the direction of air-flow?

yes,this router fan help keep your A/V equipment from overheating. (if you are looking at the label the air will flow towards you)

Product title says 102cfm, but description says 2x73.8cfm. Which is it? It’s not combined because that’d be 147.6cfm

The fans are distinct but not well shrouded from each other. I have experience with water turbines and this is much less dense but still fluid flow. My guess is that there is a small amount of interference between the fans, which degrades performance.
