Okay
I just asked corsair if it's an issue I'll let you know what they say
If we loose a feature...

It's not an issue Mike, mine works perfectly as is. The only feature you'll lose (I think) is they're not PWM fans.

I have no problems with the stock 4 pin PWM fans, there`s no reason to ever put them at full speed, so noise is not an issue, quiet or balanced mode is fine.

Performance mode lifts the case off the desk just kidding.

I think Corsair should give everyone an H110i GT

PWM-
PWM means pulse width modulation. PWM is when you pulse a DC voltage off and on. The pulses are going so fast that they do not turn the fan off and on. All the fan sees is the "average voltage".

For example: 12V going at a PWM of 50% is the same as 6V into the fan. 12V with a PWM of 75% is the same as 9V into the fan.

A PWM output looks like this

Regular-
In a regular fan controller you use a voltage regulator to control the fan.

Example: If you want 6V, you give the fan 6V

Advantage VS Disavantages-

1.) PWM is more efficient. With a voltage regulator if you need 6V and have 12V, the other 50% of your power is completely wasted. (dissipated as heat) PWM systems are much more efficient and wast very little power.

2.) PWM is controlled digitially. PWM is also more accurate. Because it is controlled digitally, it is easy to control from your motherboard.

If you hooked your radiator fans straight up to the Asus motherboard, it will still do a great job, and the bios gives you a lot of options as far as settings.

If I run IBT my 5 AF120 3 pin fans ramp up and down, they are connected right to the motherboard, not sure why, they are set to standard in the bios.

Good explanation Brian

I'll give the corsair link... a shot since I already have it wired up to do so

Well this is what the response was so it seems no big deal on extra un used pin

Hi, Mike,

It's okay if you use 3 pin fans, just make sure the pin is not touching to your motherboard or other metal surface which might cause a short in your system.

Use the correct Y-cable if you're paralleling fans off a single header. Or clip the Pulse/Tach wire on all but ONE fan on a header. Multiple sense/tach signals from the fans will corrupt the speed signal and result in slower fans. The tach signal is two pulses per rpm (per fan) and I guarantee the fans will never be in sync. So if you have two fans, you'll get FOUR pulses per rpm and the MB will think the fans are running too fast. The fan controller on the MB uses the tach sense from the fan to report speed and to control fan voltage on 3-wire or pulse width on 4-wire fans.

The advantage of PWM is that you get full torque because the voltage is always 12v. The voltage is just pulsed at different intervals. (Pulse Width) To make a fan run slower, the pulse width is shortened but it's still receiving 12v.

I have a couple of pieces of shop equipment that use 90v DC PWM controlled motors. It makes a HUGE difference in low speed torque verses simply reducing the voltage to control speed.

I'd have to lean on Gav or Brian for the tech stuff on how the corsair link software works with tuning...
As far as I've read the mobo will only report rpm's being used
Any adjustments will have to be done with the corsair software.
