I just purchased my Swiftech H240-X and I used the included PWM fan splitter. I attached my fans to the splitter, connected the splitter to the CPU_FAN spot, and below I attached the CPU Block to the CPU_OPT port. When I boot, it does not detect the CPU fan. All the fans connected to the splitter are spinning. When I go to BIOS to control the fan, they do not slow down. What is the issue? Any help would be amazing.
