Both 3pin and Molex fan power connected

at the same time? Will this cause any problems? We have a fried motherboard...wondering if that would do it.

Possibly the molex is putting out full voltage and the motherboard is trying to regulate fan speed with voltage.

Thanks, so could that possibly ruin the fan OR the motherboard?

Possibly.
