Maybe he wants to control the fans. Which would require the motherboard headers or fan controller and not the PSU molex cables running them at 100% all the time.

exact reason why I just spent a few extra bucks to get a fan controller. I really don't need my fans running at 100% when I'm trolling forums, writing emails, or paying bills.

could just make a up down switch with the 5V and 12V but Fan controller is easier way =).

I made a custom on off switch, wouldn't imagine it being too much harder to make off function instead switch to a 5V line and on function 12V line.

FWIW, on my last mobo (P35-DS3L), I was worried about overloading the CPU fan header by running push-pull fans on the cooler, so I emailed Gigabyte tech support about it. They told me that the CPU fan header on that mobo was capable of providing up to 3.0A (see last post). The P35-DS3L is a lower end mobo from Gigabyte, so I'd expect the better models to provide at least that much.

With that said, I'd recommend either some really quiet fans, or a fan controller. They will be running 100% all the time if you power them directly from the PSU, and not all mobo fan connectors are made to throttle fan speed. I use a Lamptron FC4 for my Scythe fans because they are stupid loud at full speed. I crank them up when stressing my rig, but otherwise I leave them set slow and quiet. The FC4 is one of the cheapest controllers from Lamptron, but it does what I need it to. I even replaced the blue LEDS on it with red ones to make it look better and match my other lighting. It was a cheap and simple mod on that particular controller...about $15 for a soldering pen, desoldering braid, solder, and LEDs.

I would spring for a fan controller. I usually have my fans around 50% when not gaming to reduce noise and reduce dust intake until I game then it's 100% for them.

agree with you i done that with my extra fans
