Questions about this item
What does the 0.77 A current draw mean for my fan header?
The fan draws 0.77 A at 12 V, so your motherboard header or fan controller must be rated for at least that much current per channel.
The listing mentions a tachometer — what connector standard does it use?
A tachometer signal requires a three-pin or four-pin fan header; the third wire carries the RPM signal back to the motherboard.
