## Questions & Answers

**Q: Can someone explain how this differs from the non-pwm version?  Is it just the number of wires?  IF so why would one select that over the alternative?**
A: PWM or pulse width modulation is one of several methods to control motor and hence in this case fan speed.  The correct motherboard connection as noted below permits the fan speed to be modulated to increase cooling when computing loads are high and slowing the fan at other times.  The only benefit being less fan noise.

**Q: Is this really a 4-pin pwm fan?  the noctua site lists it as 3-pin.**
A: NF-A6x25 PWM is a 4-pin fan.

**Q: Can this be mounted in place of a 50x50mm fan?**
A: No, not unless you have room for it and can enlarge the mounting hole pattern and fan hole.

**Q: Can you convert this from 4 pin to 2 pin?**
A: It comes with PWM to three pin adapters....  You'd have to hack up your own PWM to DC adapter

### ⭐⭐⭐⭐⭐ Review
*by A***N on 11 September 2021*

I use two NF-A6x25 PWM on my DELL T5810 to help cool the internal. I initially use 4 pin to 5 pin adapter and connect the two FAN to the HDD fan header but it turn out the speed is too slow to be useful. I end up buying SATA power to two 4 pin fan adapter (this will make the fan run at full RPM as it connect only the two power pin @ 12v) so I use the Low noise adapter cable supplied included in the noctua fan to make the fan run at lower RPM instead of full RPM. My setup is one fan at the back for exhaust and another one in-front of the CPU to push more fresh air into the CPU. My CPU temperature is 3-5c cooler, for light work (browsing / watching youtube will be 35c-40c) with room temperature of 28c. The two noctua fan are practically silent and I didn't notice any noise increase by installing them.
