AC Infinity has been mentioned, but with only 1" clearance you might need the MULTIFAN S2, QUIET USB COOLING BLOWER, 120MM.
I was in a similar situation and the rubber feet can be removed to fit the space (gently extend the upper towers and at the same time pull on the feet). I've not experienced any issues with the feet removed and 100% of the air is pulled through the equipment vents. Two would be ideal.
The CONTROLLER 2 has a sensor and controls the fan speed. Add the AC INFINITY, BLACK CONTROLLER STAND and it looks great.
I went with the CONTROLLER 8 with four zones as I believe all equipment sounds best when kept as cool as possible.
