Under 50db is a large term

Since 30dB is a quiest room or whisper.

26dB is whisper quiet. Or very quiet.

The fact is to move air in a gaming or powerful rig, you'll have some noise. NEVER SILENT as in below 20dB.

26db is not very quiet on PC case

I am okay with some noise, but on full speed, 26db of that CM JetFlo is very loud. I was thinking of some silent fan recomendation (~15db), some user experience would be helpful.

To get to 15dB

You are looking at fanless designs. The heatsinks must be about 4 times the size. So it's not a fan issue yet. It's a redesign and picking new very large heatsinks.

That and using PWM you may get the fans to be nearly still until the load increases.

Yes I've build such but never on gaming or "compute" rigs. The goals are at odds on those.

So there it is, you need to rethink the heatsink selection.

I was not thinking on fanless design

I am searching for some good fans (PWM or not, depends on noise) like Noctua redux series, Artic F14, CM silencio...

I was hoping I would get some specific recomendation for my Phanteks case. Happy

With your goal of 15dB
Mar 30, 2016 8:50AM PDT

You have to move to very large heatsinks so the fans can barely move. This is your requirement so you have to change the other part as well. No fan I know is 15dB unless it's barely moving because we fitted a much larger heatsink.

By your own requirements you are looking at fanless designs.

No fanless design

Noctua redux series offers many fans from 6,8db to ~17db. But I was looking for more budget solution Confused

Given your low noise requirement

Big heatsinks are needed. I guess you are not getting it yet. You need to take your best shot at fanless but with a fan to move slowly some air.

Otherwise you are hunting for the purple unicorns. I have yet to find a full say 60 CFM fan that gets under 20dB.

I think that Noctua have fans that are going under 20db with 60CFM Happy In idle mode I need silent PC (useful while surfing at night), when I gaming noise doesn`t matter to me because I use headset Cool I will probaly try with Artic F14:
