They are basically an industrial sized fan that supports 6 to 30 volts. I would get 12 volt fans, as the 24 volt ones are for use in industrial environments and not home computers. A PC power supply, including the ones that Alienware uses, does not provide a 24 volt plug. It's typically reserved for server grade PSU's.   The new NF-F12 (120mm) and NF-A14 (140mm) industrialPPC-24V models use a dedicated wide input range version of Noctua's NE-FD2 three-phase motor driver IC. Supporting operating voltages from 6 to 30V, these models are ideal for 24V-based industrial applications and voltage-based speed control. All new models feature IP67 water and dust protection and PWM.“As our industrialPPC models have become quite popular among PC enthusiasts, we think that the new 24V variants can also be interesting for PC users due to their wide input range”, explains Roland Mossig (Noctua CEO). “When you run them at 12V, you will get much lower speeds and noise levels, so they combine the advanced features of the industrialPPC line with the renowned quietness of our standard line-up.”While the industrialPPC 24V models have been designed with 24V industrial applications in mind, they run at maximum speeds of around 1100rpm (2000rpm models) to 1700rpm (3000rpm models) in 12V PC environments. At the same time, they can be slowed down further via PWM, thus combining the advanced features of the industrialPPC line with Noctua’s signature quietness.
1) I was wondering if I could replace All the 120mm fans with 24V PWM fans. 2) I want to replace stock fans with (Noctua NF-F12 3000rpm PWM 24V or NF-F12 3000rpm PWM 12V) or will either of them would work?. I would like to replace the liquid cooling stock fan with one of these fans. I hope someone could answer my question.
