Hi, so I have 3 case fans and a CPU fan. However, my motherboard only has 2 system fan headers while the CPU fan header is used by the cpu cooler. I have connected the rear case fan to one of the system fan ports but the other 2 case fans I connected them to the PSU via molex. I know that there is an option of choosing a fan hub, but if I were to leave the 2 fans connected to the PSU, will it pose a problem to the other or will the fans alone just be less durable? Thank you.
