I got lucky and now I can hit 1 GHz easy with 1.165 voltage while the Hawk made it only upto 890 GHz with Afterburner +1(00) voltage bump.
But the topic is about cooling and temperatures. Hawk, just like any other 460 and (560 I guess) when idle is completely silent. I even bought Palit GTX 460 768MB with black aluminium heatsink (no heatpipes whatsoever) and it was completely silent when idling. So no problemos in silent mode with any card guaranteed. The difference shows up when the card is engaged in gaming, especially if overclocked. The Hawk Twin Frozr at its default fan settings started to get audible even at the beginning of the games so I had to use custom fan settings to hold the fans at 50% until it reaches 70 degrees Celsius. The default fan speed of the Hawk is 40%. At 47-48% you start to hear the sound of the fans. At 60% it got pretty loud for my taste. On the other hand DirectCu starts off with 20% with its larger 92mm fan. While gaming (default voltage 0.962) with the maximum clock of 870 Mhz (default voltage) the fan rotates maximum 39% and it is completely silent. You can hear this fan above 50% but it is still less audible than the Frozr was when rotating at 50%. My case is HAF 932 with fans on.
The DirectCu is completely silent at idle and load, and is less audible than Twin Frozr II guranteed. I can not say anything about DirectCu II because it is a different cooler compared to its predecessor and has 2 fans but I am sure that it does a better job than Twin Frozr which remained the same. And for gods sake, I beg MSI to put heatsink on the VRM section. It has been left out on 560 as well.
You already answered your own question: ASUS uses a larger fan vs. the TFII solution.
As for DirectCU II, go read the Tech Report review. It is *NOT* better and is the worst out of the 3 cards tested.
As for heatsink.... it's coming. Just not out of the gate.
