Fan Control for 10 San Ace 9g1212h1011 - Page 2

Can you still control the rpms with more than 1 fan per channel, even though the readout won't work?

If so I could hook up one fan for the reading, Mark around the knob with some thinnly sliced green and red tape for different speeds.

RPM sensor would be good too so I know how fast they are spinning.
Yes, get the Sunbeam Rheosmart. It's the same thing, except it has PWM control built in. Don't put 6 on one channel though, because the controller has 30w peak wattage per channel. Each fan is just under 5w nominal load, but wattages can peak. Without slapping a multimeter on the channel and verifying that peak wattage doesn't exceed 30w, you can't know for sure, so it's best to play it safe.

I'm not sure I understand what that would accomplish...

What is PWM Control/PWM?

Pulse-width modulation in PC terms allows you to manipulate the power received by a device within the operating system. You can basically control the rpm of the fans with a program like speedfan.

So with PWM I can use a program to control the fans and set up alarms using the motherboard heat sensors?

What about if there is more than 1 fan per channel?

Be careful with putting fans in parallel on your fan speed controller. I have 4 10g san aces on my quad radiator hooked into a channel of my sunbeam rheobus (6 channels, 30 W/channel). It seems that some of the fans spin faster than others. My guess is that the fans arn't totally identical to each other. This problem would probably be alleviated by adding a bit of resistance in series with each of the individual fans, via one of those fan silencer adapters. Also, the channel heat sinks get pretty ******* hot.

Yes you can. There is one PWM per channel, so you would have to connect all the fans on that channel to the same PWM. The software will treat it like one fan, when in reality you have multiple fans.
