All Thermaltake software can be downloaded by visiting www.thermaltakeusa.com and clicking on the support button under downloads.
To tell whether you are supposed to use our software or your motherboard software is easy. If you are using any fans that have ARGB in their name like the image below, you are supposed to use the motherboard's software. This is also true for all LCGS custom computers, they all use ARGB hardware and would use the motherboard's software. Please see your motherboard's manufacturer page for their software download.
* Note: The only piece of hardware that will use both programs is the TH V2 Ultra series AIO water coolers.
