The Extender Range (ER marking like EK-Vardar F4-120ER) Vardar's offers 25-100% PWM duty cycle.... which means you can get them down to 350-400 RPM. Depends on the mobo too. A friend of mine managed 350 on an ASUS X99 board.

geggeg tested them all. F4-120ER averaged 365rp m @ 18%PWM -2171rpm @ 100%PWM

This is what not-so-well-sounding-Vardar fans sound like around 1000-1100 rpm.
I have NOT turned up the mic or anything. This is exactly as I hear it ~50cm (~19,6 inches) away.

Can you do a video with first the Vardars and then the Noctuas? So we have something to compare them to. thumb.gif

This my Noctua NF-F12 IPPC-2000 and EK Vardar F2-120.
First the Noctua's and then the EK's, both at 1000 rpm. Nevermind the starting boost.

I have. The fans in the video are the fans from the original purchase. I have done RMA two times. The ones I have now are much better, but still not silent enough IMO

Both fans sound fairly abnormal, I can detect the weird tone in the EK Vardar fans but even those Noctua fans sound like big turbines. I have a feeling your microphone gain is increasing the sound amplitude as I can hear a lot of noise as well, so I am not sure if this is indeed how it is for you with the case window back on and you a few feet away.

Of course, it depends on the volume on your speakers/headphones. When I listen to it I have the the volume way down, just showing a little bit of the white of the volume bar. But I can hear the grinding sound from 10 feet away. Even with the sidepanel on. And as I said, this are the fans from the original purchase, not the ones I have now.

Well my basis was you saying you could hear that from 10 feet away, so it's fairly impressive that those fans are all that loud then at 1000 RPM biggrin.gif

Can these be used as case fans?
