The Quark line of ESC's are not over rated. They will deliver the amperage they advertise.

The catch is the liniar Battery Eliminater Circuit they have built in, isn't capable of carrying the Receiver/Servo's when powered by more than 4S.

The internal BEC just creates soooooooo much heat. Even on 4S, by adding a Castle Creations BEC circuit, ESC temps will be reduced alot.

In other words, if you're NOT using an External BEC, the majority of the heat that you are seeing isn't necessarily coming from the Power FET's inside the speed controller. Most of the heat is coming from the internal BEC that just can't keep up.

The Castle Creations BEC is soo nice also. It gives you the option to adjust the amount of voltage supplied to the Receiver/Servos. I have mine set to 6.0 volts. This makes the Servo's stronger and faster than powering them by an ESC (5.0 volts).

Look in your Quark manual under "Opto-mod" for more information on using an external BEC.
