The problem isn't overrevving the motor, the problem is the motor pulling too much current. All of the references I've seen show the 1105/1Y to be a 10,0000 Kv, 200 watt motor. I'm not familiar with the S3.2 designation you tacked on, but since you say the Kv is only 4550 I have to assume that is some type of gearbox.
So, working with a Kv of 4550 and a 4.7x4.7 prop it looks like a two cell battery will get you a bit more than 24,000 RPM, 35 amps for around 240 watts and a pitch speed of 90 mph. You will note that the current is substantially below the capacity of the ICE75 ESC and the power is a bit above the motor's 200 watt rating. However, with good cooling you can probably get away with that.
Another thing to note is that the motor current will increase approximately with the square of the battery voltage. So, even though with two cells the current is half of the ESC capacity, doubling the motor voltage by going to four cells will increase the current by a factor of four. That would be twice as much current that the ICE75 is rated for. It's no wonder it wouldn't run with your 4 cell battery. By using 3 cells as you're proposing, the motor current will increase to around 80amps and the motor power will increase to over 800 watts both of which will definitely fry the motor.
Lastely, what you need more than the Castle Link is a watt meter and a better understanding of how motors work.
