can you hear the fan, how quiet is it?

Yes you can hear it at every speed, even on the lowest speed. I have the two-fan 6-inch version (total 12"x6" grille. I'm a LITTLE disappointed but not enough to prevent me from purchasing another of the same for the Receiver area of my AV cabinet. Do NOT expect these fans to be silent.

How can I control when this turns on and off without having to upgrade to the model with a thermostat? If I plug it into my Yamaha receiver usb output

It has a toggle switch. Manual, but not terrible. If it's plugged into something that you turn on and off, it'll run when that component is turned on.

Is it better to Mount where the Fan pulls out the Heat from the Cabinet or better to blow Air into Cabinet?

It's better to mount where it will pull the heat OUT, thereby bringing in cooler air unimpeded by other airflow inside the cabinet. If you blow air into the cabinet, it may not be able to exit as quickly and you would get air blowing back around the inside of the cabinet and impeding airflow into the cabinet. Think of it his way, if you blow into a paper cup with a fairly small hole in it, you can only "blow" so much air in and the rest comes back out at you. to avoid this potential problem, you will get the maximum airflow through the cabinet by pulling in air that is exhausted out by the fan.

What is the size of the hole that has to be cut in the cabinet?

The fan comes with a clear plastic template to guide you. Just tape it to the cabinet wall you are mounting the fan onto. The hole is about 5 inches square. The face/lip of the fan is about 5 3/4 inches square. You also must drill 4 holes for the mounting screws - also made easy using the template. For me, it took 10 minutes to hand-saw through the thin, paneling-like board backing of my entertainment cabinet. 10 minutes to mount the fan with 4 screws. It took 2 minutes to plug it into an unused USB port on my amplifier for fan power. Now, my whole 7 component system stays cool. After watching a movie, it took 15 minutes to clean up my mess.
