i have a denon avr s940h reciever in an enclosed cabinet with 4 inches from top of reciever to top of cabinet. Will the s9 or t9 work?

4" from the top of your receiver means only 2.5" from the top of the AIRCOM S9. This may be too little clearance for a top-exhaust unit. You say "enclosed cabinet." I assume one side is open. The hot air needs to vent somewhere. If this is true then go with a front or rear exhaust system instead. The AIRCOM S10 is the front-exhaust version and S8 is rear-exhaust. Also, I like the S-Series because it offers all the control over the fans that I require. The T-Series costs more and seems a little overkill. Unless, however, you really like the LCD display.

Will this work in automobile applications

It works off of 120. You should call the company and ask them if they have fans for automotive applications.

does anyone use these fans in a stack? in between 2 components (amp, fan unit, avr for example)?

As long as you have proper clearance I don't see why it wouldn't cool ok. I think it pulls air upwards better than pushing air but I have used it to push air up thru an amp.

Have a receiver in a cabinet with 3.5" space behind it to back of cabinet or about 5" above it to a glass shelf. Top or rear exhaust unit is better ?

This unit exhausts from the top and I have about 1 inch above the unit. It works perfectly. I’ve had no problems with the receiver overheating, since I purchased the fan. If you have 5” above, it should work very well for you.
