## Description

Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame, the NF-A4x10 is an award-winning, premium-quality quiet fan in size 40x10mm.

Review: Beautiful piece of engineering. And the packaging... Wow. Speechless. They've included everything you might need. The airflow is weak though, but what would you expect from the fan of this size. Oh yeah! And it's super quiet.
Review: My PC's CPU temperature was low (35 – 52 degrees). However, the Z690 chipset was hovering around 80 – 90 degrees. Way too hot for my comfort. Made a simple mod by zip tying a 4cm Noctua fan to blow directly at the chipset heatsink. The temperature drops to between 61 and 69 degrees. ASUS made a mistake of removing the heatsink fan for aesthetic reason.

## Questions & Answers

**Q: What's the cfm?**
A: This fan is rated at 8.9m³/h and 6.6 m³/h with the LNA, this converts to 5.23834215487808 CFM and 3.88461328339273 CFM with the LNA

**Q: Will the fan operate off a 2 pin 12V DC supply?**
A: Sure, when the PWM has a pull up, this means the FAN will run at 100%.

**Q: Can this fan be used in place of the noctua nf-a4x10 flx?**
A: There is no reason why not, but do not expect to get the RPMs as low as you can using a PWM signal
be aware this model can get a little louder than the flx version as the max fan speed is higher, but that does come with more airflow and static pressure

**Q: can I run this off a 12v fan header on my motherboard/fan splitter?**
A: yes, you can use as many splitters as you like, just check how many amps your board header maxes out at and add up your fans current draw, this fan is specked at 40 milliamp, 1000 milliamp = 1 amp
