Computer help: Can I run 2 fans on 1 fan plug-in?
Can I run 2 fans on 1 fan plug-in?
by docism - 4/28/06 12:30 PMI noticed that 2 fans (on the back) were running from a power connect directly from the 650W power supply.
Can I run both of these fans from 1 fan plug-in from the mother board?
I wouldn't

Not always. . .

The fan connectors on the mobo

Although when hot it can provide 12 volts, it cannot provide it with sufficient current to power two fans. Good chance that you could burn the chip out.
Another negative

The current draw maybe too much for the simple land wiring of the mtrbd. and blow it like a fuse or curl it off, not good. Since, you mentioned a 650W psu, a direct hook-up isn't going to hurt that wiring from a fan. check, your mtbd. there maybe multiple fan hook-ups that maybe not apparent, but 1 fan per connection.
