Hi, I have a question.

I have both the Cuplex Xt di and the new Cuplex HD (in order).

Since I am now rebuilding my two systems, I am wondering which of these blocks that will perform best on an OC qx9650, that runs pretty HOT. OK I know this also depends an the radiators, but I have sufficient radiator power (single+dual+triple) in my rig.

So, does AC or others have a flow vs cooling performance graph or something? Or at least an indication at which speed the the HD out performs the XT di. Or will the Xt di always be better, but with a higher flow resistance?

I am grateful for all answers and discussions on this topic.

Thanks shoggy.

This answered all my questions. (And I axctually preferred the german version. I read german quite well, although I dont write).

But the conclution is that the HD always will perform better than the Xt di, which leads to another question. Are you planning a HD version of the chipset cooler?

Thus the only reason for choosing the more expensive Xt di is the fantastic look!
