So here is the phase where we slowly start assembling a test setup. First we mount the two fans to the radiator, four screws each. The fan casing is made out of rubber, not hard plastic. This greatly helps against vibration etc.
Once done, this is what the unit looks like. You need to decide where you'll be positioning your radiator and how the tubing and wiring will be managed.
The two fans have connectors you can merge together with an included PWM cable hub, this leads towards the CPU FAN header on your motherboard (or whatever source you like to control the fans from). For this kit please understand that the motherboard controls the PWM fans. You can also directly lead both FAN cables to your motherboard fan headers of course. But less cable clutter is always better IMHO.
