Hellvetica5 years ago000I can't find a very important manufacturer's note for this product? A single Polaris RGB fan (single pack) cannot be operated alone. A set of two Polaris RGB fans (twin pack) must first be available in order to be able to connect further fans. Which leads me to question two. Why don't you have the Twin-Pack in your range? I hardly think anyone would combine a transparent Twin Pack with a Single Aluminium Pack...Show in original language (German)2 answers
