It throttles not only for heat but, also power consumption. It's a 450W card in a 300W package, so it's going to throttle hard regardless of temperature.
Theoretically this card is capable of ~ 290 KH/s on WPA2, but you're only seeing ~ 233 KH/s with an overclock -- about 20% slower due to PowerTune throttling. And if you were to set PowerTune to something like +50% you'll likely start a fire attempting to get more performance. This is why we strongly recommend avoiding AMD GPUs.
