Questions about this item

Does the 4-wire connector carry the PWM signal needed for 12 V .6 A fan speed control?

Yes, the four-wire lead includes the PWM line so the motherboard can regulate the 12 V .6 A fan speed automatically.

Will the 80 mm by 20 mm frame screw directly into the OptiPlex 790 or 990 SFF chassis?

The cable is made for the 80x80x20 mm fan used in those SFF models, so the mounting holes line up with the case fan brackets.
