How do I connect my GPU cooler?
Our graphics card coolers can be connected in different ways. Most coolers and cards can use the regular fan connector on the graphics card. However, with newer "RTX" graphics cards a special adapter cable is included. If the cable is not included in the scope of delivery, please send a short message to customer service with proof of invoice and the shipping address. If none of the connection options mentioned can be used, the fan can be operated via a special "4-pin to Molex" cable with a fixed voltage of either 7 V or 12 V. The fan speed is fixed and cannot be regulated. 7 V represents a compromise between volume and performance, while operation via the 12 V cable allows maximum fan performance.https://www.arctic.ac/en/How-do-I-connect-my-GPU-cooler
