Hello guys,

I'm looking for a 140mm static pressure optimized fan for a radiator. It has to as quiet as possible. Basically I'm looking for something that has the best performance/noise ratio (which you could express in mmH2O/dB, I suppose).

I tried to get the ratio out of these graphs https://docs.google.com/file/d/0B1PSGh26Ne0XcG01LU5LaU9XX2M/edit and got that the Corsair SP120 Quiet edition had the best, only it isn't a 140mm fan. Bummer.

So, if anyone knows a 140mm fan that is quiet as hell and still blows like a hurricane, let me know!

Thanks in advance guys.

You can get PWM (4pin) versions or standard 3pin versions. The 4pin versions will work on 3pin headers, and you might be able to run a 3pin fan on a PWM header - depending on your mobo you might be able to change the setting on the CPU_Fan PWM header to run voltage control. Most high-end boards that I've looked at can detect the type and switch automatically. If you're running the fans from the mobo, you can adjust the speed of either type through your BIOS or through software. The 3pin and 4pin fan connectors are all compatible with the mobos headers.

You don't want to run these fans more than one per header - the regual NF fans are very low wattage and amperage, but the industrials pull .55A and 6+ watts. You could use a...

I know, that's why I want to go for the sweet spot in the mmH2O/dB to get the best static pressure at an inaudible noise level (though I might have to turn the RPM down).

Love this suggestion, if anyone else knows another option, post down below. If not, I will grant you the best answer in a few days. Thanks man!

De nada. I'm looking to buy a set of the 2000 RPM fans myself. Don't really need them, but...

Indeed, they're very good fans. However, if you go back to the original post at the top of the page, you'll see that the OP has already considered and rejected them as unsuitable. He's looking for the "Best and quietest 140mm static pressure fan", hence the title of the thread. If you know of any high-quality, high-static pressure, quiet 140mm fans, by all means throw the name in the hat. Don't bother with Noctuas as an alternate though - they've also already been presented.

By the way, as the industrial version has higher rpm, how can I turn them down to make them quieter? The fans are meant for a radiator in a loop for my graphics card only, so the cpu fan header is already taken. Also doesn't it only have a 3-pin connector? I really don't know much about fans and setting their rpms.

You don't want to run these fans more than one per header - the regual NF fans are very low wattage and amperage, but the industrials pull .55A and 6+ watts. You could use a splitter and run an industrialppc and a regular fan, depending on its power requirements, off one header using a splitter, but one fan per header is best.

You can look at adding an aftermarket fan controller also.

This is in the sweet spot. 41.3 dbA is almost dead-silent, and you can use softwares to turn the speed down a bit to make sure it's completely inaudible, such as Asus AI Suite 3for Asus motherboards, Easy Tune5 for Gigabyte ones, OCTuner for ASRock; however, if you're lazy to search and download them just buy a low-noise adapter. The voltage would keep the noise below the audible level

get a fan with good static pressure and use rubber mounting spacers, noctua sells them. As 90% of the noise will come from vibration through the case. I installed them in my pc and the difference was amazing.

The noctua 3k industrial fans have 10mm of pressure and are also pwm fans. It's just way to loud. DBA ratings are exponential btw it's not like 50dba is 20 percent louder then 40dba it's much more.
