I am building my first computer and I am having a problem with the case fans. Sometimes the fans (on High) will not start when the computer turns on, but I find that after a few minutes they will come on. The fans are very low when on "High" setting and stop spinning at all on the "Low" setting.
I have an Antec Three Hundred Two case with 2 included fans, and a Gigabyte GA-B85M-D3H motherboard. The fans that came with the case are 3-pin fans and can connect to my mobo's 4-pin sys_fan ports, and the fans come with a controller on the back of the case for High or Low. High should be around 1200 RPM, with Low being 600 RPM. However, in my BIOS I am getting speeds of ~450 RPM on "High", and the fans come to a stop on "Low".
In my BIOS the fans are set to "Normal", which according to my mobo manual says that this allows the fans to run at different speeds according to system temperatures.
Should I be getting an adapter to connect these fans to my PSU, and then they will be working properly? Or is there something in my settings I should be changing? Or do I have faulty fans.
Thanks for your help.
