I've received the Nexus 120mm D12SL-12, and the Noctua NF-P12... and both are 25mm thick.
The thickness of a 38mm should provide more static pressure.
So the thread is now.... what are the 120x38mm fans that have the highest pressure and are quiet? I'll be dropping the voltage to reach almost silent at 1m db levels (same as SPCR's level of 19dB, or xbitlabs level of 33dB)
edit: this thread started out as a request for help. Now that I've started a list here, the thread now just welcomes posts of new fans not already listed, that have above average pressure, and low dBA.
Above Average Pressure is defined as... I don't know
![Confused :?](./images/smilies/icon_confused.gif)
Low dBA is defined as 20 dBA or less.
CFM needs to be 50 or more.
Fan size - the smaller the better[/b] .
So add any fans to the list that you know qualify (and are available to be purchased)...
And if you have any personal experience with any of the fans, please add that too.
thanks!
