Get wrecked blowie matron: overclocking 3000rpm Noctua iPPC fans to 4500rpm.

I've been looking for an excuse to buy these blowie bois for years, and I finally got one: I need to blow the output from a portable AC into another room (because I don't have windows in that room to run the exhaust line).  I was using a leaf blower (yes....) but it was just obscenely loud.

 

Blowie matron does 90L/s of air at 11000 rpm?  Hahahaha...that's pussy shit.  4 of these fans with their stock 3000rpm blow 300L/s of air.  Overclocked to 19V and ~4500rpm, that's 475L/s of air.  Or for Americans, 1000 cfm.

(It doesn't quite scale linearly.  More voltage and fan speed doesn't directly translate to more RPM and more air flow, but it's close).

 

And here's what it sounds like ramping up, I've heard datacenters that are quieter and these are 140mm fans.  You expect 80mm fans to be this loud in a 1U chassis.

 

 

You get 19V from a laptop charger easily + solder on some molex adapter.  I've killed normal A14 fans with 24V but 19V seems electronically safe...who knows what happens to the bearing lifespan though.

 

EDIT: Gotta bump this up to say: don't shove more than ~16.5V into these fans.  17V killed one of them within a few hours (my guess is that it doesn't like having 0V->17V jump), but it may be OK if you slowly ramp the voltage up.  16.5V though is totally fine so far.

Kinda like mine, but I’m using 120x38s at 12v 🤘🏻

You're a madman installing fans like that in a desktop.

 

But I respect that play.

Thank you sir. It’s quiet most of the time as I run them at 7v. I wouldn’t mind trying yours out. X58 can be warm.. but not with my setup 😄
