Guys,
Been thinking of doing someit with my PC for a while now as it is too loud.

The rig sits on the desk right next to me so I need it to be quite quiet. Am running two Akasa 12cm fans front and rear, the blue neon light type.

2 seagate hardrives 7200.9 150gb 'ers, and a Zalman CNPS9500-LED Cooler.

Too be honest I unplugged one of the rear fans and it seemed a lot quieter.

What software can I use to slow the fans down as the quiet BIOS settings do naff all. Or would it be best to purchase a fan controller.

Please help my hearing is at stake here :rolleyes:

Don't bother with Zalman case fans... not as quiet as I expected :(

The 80mm ones are superb. Was this with or without the supplied resistor?

I have the same blue led akasa fans as the op, they are very noisy at full speed but undervolting with a fan controller will help a lot. However i find they still click even on lower speeds, so if you want it to be really quiet you'll have to replace them i would think.
The s-flex ones mentioned above would be perfect.
 
One of the problems could be that the fans are restricted by a grill to stop you chopping off your fingers. With any case I get, I always dremel out the perforated metal grills, file it down so you don't cut yourself when installing the fans, then either leave it bare, or put on a nice wire grill (you know the type...the ones that are normally on PSU's).

Next step, some quiet fans and a fan controller. I've got an akasa jr. and it works great. No overcomplications, just does what it's meant to. No fan is silent at 12V, but if you get a quiet fan, drop the voltage to 9V or so, and you should have a very quiet fan. The acousti fan mounts are awesome at removing any vibrations. The noctua S12 fans are very decent, and also come with the fan mounts, although scythe, sharkoon and yate loon are also v.good.

I know that seems like a lot of effort, but for silence, it's worth it!
 
If they are plugged into the 3pin headers on the mobo, try speedfan! Great wee program. Akasa ambers are known to be quiet. ;)
 
I got some Sythe S Flex 1200rpm cant hear them above my corsair 620W psu fan so its extremely quiet, but the main thing is that such big fans vibrates and it makes my case panels resonate which by far the the most annoying thing. Ordered some silicon mounts and shoved foam in between the side panels which I hope will reduce the vibration.

Yeah?

Putting the resistor in there only makes them run slower doesn't it? I have them installed on my fan controller (without resistor), but I'm just not hugely impressed by them even on low settings - which would be the same as using the resistor I guss. Freakin' expensive too! But all of the quiet fans are a little pricey.

Next thing for me is quietness - when (if) I get my next paycheque I'll get a Tuniq and a few of those S-Flex or Noctua fans methinks :)
 
After going through Zalman-F1's and Sharkoon Silent Eagle 1000's I have ordered some Noctua 1200rpm's and am going to be giving them a go this weekend. Will let you know how they turn out in terms of airflow/noise. These are all 120mm fans by the way.

Expensive?
The Zalman 120s are cheap, only about £6. I heard from others that with the resister they are very quiet... :confused:

Yes the resister makes them run slower, but they run at a high speed to begin with. Its effectively a quiet mode switch.
 
Heh yeah you're right - I thought I paid a lot more, but checking the place I got them from they're not that expensive.

They do go quiet - but I have to turn them pretty damn low, and on low they hardly seem to push any air :confused:
