While I do not want to believe you are being evasive, you seem unwilling to answer my question. While I do not expect a college level essay answer consisting of who, what, when, where, why, and how come and the significance, I would appreciate a direct response. For example one is made of 100% Aluminum and one is made of Aluminum Alloy including Zinc. The Fins per inch on one is X fpi on the other it is Y fpi. The direction of fluid flow is ABC on one the other is DEF. With identical fans one radiator has a cooling capacity of X℃/minute and the other has Y℃/min. I am not trying to be difficult I am just trying to make an informed decision and I feel I need more information than I can find on the Thermaltake web site. However, if this information is more than Thermaltake is willing to offer, please let me know so I may look elsewhere for my liquid cooling needs. Thank you!!
