Posted January 30, 2016 I recently bought the aforementioned coolers for 2 computers and, to my surprise, the Noctua is WAY noisier than the other. Especially if the biggest fan is set at 1300 RPM, the noise level is way beyond the case fans (default Antec GX300 fans, Antec Tricool or Twocool I think). It's noisier even with the fan at 650 RPM), but somewhat better. Cooling wise, it keeps a non overclocked i5 6600k Skylake at 50 Celsius while running Prime95 max heat test for an hour. Room temp is about 22C. I assume this is good, right? But I'm really bothered about the noise and from what I read it should not be like this. Is it possible that I got a defective unit? Any other causes? My case is smallish but I listened to it with the side open and clearly it does not touch anythinh or something and the big 140mm fan is really loud. What do you guys think?

I have never found noctua fans to be silent at 12volts, you have to undervolt them, 7v is acceptable, and 5v is ideal. The reason noctua fans are so well regarded, is because EVEN at 5v, it outperforms other cheap fans at 12v and higher RPMs. Link to comment Share on other sites More sharing options...

Posted January 30, 2016 Why in the world would you run 140mm at max speed? It is silent if rpm's are low Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted January 30, 2016 Author The 140mm fan is pretty noisy at 650 RPM too. About the noise level of case fans at the same RPM. From the bios I can set fans at 1300 and 650 RPM. My MB is a Gygabite Z170X Gaming 3. Can I set the voltage from somewhere? Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted January 30, 2016 Check the fan speeds ... it doesn't need to run 100% even at full loads. Magical Pineapples
