I am preparing to setup hardware for custom liquid cooling. I didn't opt for a kit & now I have all parts needed from different manufacturers. The only Corsair component I have is the ZD5 RGB pump reservoir. I read somewhere online that the controller & it's software will only work with Corsair hardware. Is this partly or completely true? Is it just a marketing stance? Your relplies will determine if or not I should purchase the Corsair Commander Pro controller. Thanks for your help.
