I'm thinking of getting 5 of this. since this is a pwm, i'm thinking of getting swiftech 8-way pwm splitter with sata power connector. will this work?

yes, it will work with the swiftech 8 way plitter with Sata connector. the previous answer was misleading. those 4 pin Noctua fans utilizes Pulse Width Modulation (PWM) to control the fan speed, not voltage modulation. Hence it will work with the Swiftech 8 way 4pin Sata splitter which is also Pulse Width Modulation controlled. i have 4 of this plugged into the 8 way swiftech splitter with the sata connector and all four are ramping up and down RPM accordingly. so yes, you can fully control the fan speed.

Should i take the 2000 or 3000rpm version? Both the model has the same minimum rpm? If so, 3000 provides more options for the future?

The poster is asking if both fans are running at the same rpm, which will be louder? Which will be more effective? The 3000rpm fan, slowed to 2000rpm? Or the 2000rpm fan running at 2000rpm? That's the real question and I would also like to know the answer to this.

Does this only work with a 4pin connector, or can it also be used with a 3pin?

They'll also work with a 3-pin connector, but you just won't get the PWM control through your motherboard when connected to a 3-pin.

Is it a 140mm or 120mm?

The NF a14 is 140 The NF f12 is 120. The two numbers give away their size. I have both. It is the best fan ever. I have 15 in my case. X14 120mm and x1 140mm. Two Monsta 360 rad, push pull. Get them and you won't regret.
