Hi again,
I am quite obsessive with quiet - as leave my PC on nearly 24/7
I made the mistake of buying
Sharkoon Silent Eagle 2000 fans as they have excellent CFM to noise ratio's...
Maybe to a DB meter they are quiet. But to my ears the "golf ball dimples" give the airflow a rough edge to the sound.
I replaced all my P182's case fans with these - I partly wanted a set of quiet fans that I could connect up to my CoolerMaster CoolDrive 4 fan controller.
Even on the slowest fan speed setting these 2000rpm fan max speed fans were too loud - 1300rpm on min I think it was.
I fixed this by adding inline 5v resistors after the fan controller - now at 840rpm I finally have peace at night.
Sorry to go on on that but...
The fan on my Hyper 212 was a different storey all together!!!
I removed it to compare it at the time to the Sharkoon's (which do have a nice high air flow to be fair).
All my tests were purely subjective of course.
The Sharkoons seemed to shift a tiny bit more air for same fan speed, maybe.
But Damn, next to them the CoolerMaster fan was bliss, producing a completely different noise - much more like a soft purr.
The sound, Very quiet even mere inches from my ear (all at lowest settings so far 1260 without the extra resistor) was so relaxing I could imagine easily drifting off to sleep.
At max speeds both fans made a fair bit of noise. But even OCing my Q6600 @ 3.6GHz and folding@home (really stresses the CPU) I found about 3/4 fan speed setting to be optimal - Max speed made Much more noise for little effect on temp.
Am guessing you don't have a fan controller, so just stick with the standard Tri Speed fans at min setting.
Use the your motherboard CPU fan header, set the 212 Plus to min speed and forget...
Easy
If you get a fan controller, get something like the:
Scythe Kaze-Master 5.25" Fan Controller - Black
Review
The best feature of this one is that you can completely shut off unneeded fans by turning the dial down all the way.
Nobs protrude about 1cm and will fit behind the P182's doors just fine.
Alarm does sound when you switch off a fan - I'd disable alarm using jumper on install...
Each channel can provide 1A - so could run multiple fans off each channel.
Has 4 accurate temp probes too.
Bear in mind the Tri Speed fans with your P182 use molex connectors and cannot be plugged into this fan controller.
Got a bit carried away there, good luck with your setup ^^
