I acquired an older Super Mirco Server. I replaced the system fans with Noctua 40x20 fans to try to quiet the damn thing down. The Noctua's worked great on the system. The last loud fans was inside the PSU. I again swapped it out with 2 Noctua 40X20 fans but when i power the server on all it will do is pulse on and off. If i reconnect one of the original PSU fans back to the PSU fans headed everything work fine. Any ideas as to why the PSU wont turn on unless it has the original counter rotating fans connected??
The PSU is a "PWS-561-1H20"
