Help with Noisy Noctua Redux Fans
Posted: Tue Aug 09, 2016 11:55 pm
Hi All,
I have finally built my dream PC with the following specs:
System Specs:
CPU: Intel Core i7 6700K
CPU Cooling: Corsair H110i CPU Cooler
Motherboard: ASUS ROG Maximus VIII Formula Motherboard
Graphics: 1 x ASUS ROG Strix GeForce GTX 1080 OC, 8GB
Memory: G.Skill Trident 3600MHz 16GB DDR4
SSD: Samsung 950 PRO 512GB SSD
HDD: Western Digital WD Blue 2TB, WD20EZRZ
Power Supply: Corsair HX750i Power Supply
Case: Phantek Enthoo Pro M with Window
Case Fans: 2x 140mm Noctua NF-P14S PWM Redux Edition 1200 RPM
Rear Fan: The stock Phantek fan that comes with the case
I was hearing strange noises from my fans so did some testing and found that my Noctua Redux fans make a really strange 'woooo' type sound. Here is a link to a video I uploaded so you get a better understanding of what I mean - https://youtu.be/RH-7VOGgJ6Q
I believe the fans are connected with a Y splitter as they are both controlled via CHASIS FAN 3 in my BIOS. These fans are mounted to the front of my case and the radiator is mounted to the top. During my testing I found that the 'woooing' noise would start to be noticeable at around the 700-750 RPM mark and then get louder as the speed increases (as per my video).
So my questions are as follows:
1) Is that noise normal?
2) For case fans what is the lowest RPM I can run them at? If I manually set them to run between 500-700 RPM and not exceed that RPM they are inaudible but I'm concerned that may not be enough airflow?
3) If I were to run the fans at low RPM as suggested above what impacts will that have to my radiator cooling and temps? I've managed to create a custom profile for my radiator which is also virtually inaudible and I'm worried that if the front fans decrease their air intake the the radiator may increase its fans spinning leading to more noise
5) Finally, if I were to replace these Noctua fans (and I really feel like I shouldn't need to) what should I get that will work well with my build
Thanks in advance
