280x Best non-reference cooler?

I want to get the 280x, but I want to get the best possible card with the best non reference cooler. I have narrowed down the ones I want to the HIS x2 cooler, the Asus DCUII, and the MSI twin frozr. Which card is the best in terms of temperature, noise and performance?

Consider the Sapphire Dual-X model if it could also be an option, especially for its low idle noise. At least around here the price is nice too.
