Replacing Antec 900 Fans

So basically I'm lookng to replace the Antec 900 Fans. I'm a bit sick of the LEDS, as they are distracting and too loud. I want them to be quiet as possible whilst moving as much air. I currently have the fans at low, yet they still make a bit of noise especially when I leave my computer on overnight. I'm looking to purchase from pccasegear.com.au,ebay.com.au and any other Australian website.


Thanks
 
The LED fans have three speeds, according to the spec pdf
CFM is 39 to 79
dB 25-30
If your current lowest speed works OK then the slower speed fan that salvage-this linked would just about work. 9dB less noise.

Edit: A further thought, if you are concerned about noise at night, how about turning one or both fans off? Presumably the CPU is not working hard so heat is not an issue. You can buy fan switches for a few bucks.

Yeah those fans look good, remember i don't want LED's

@ Nanobyte, when I leave my computer on overnight it will be rendering or encoding something, so the CPU will be at full workload.

The coolermasters look cheap, but i haven't heard great things about them. I'm looking at replacing the front case fans and the rear.

What about this Noctua fan?

Which would you choose, the Skythe 1150RPM/1800 or the Noctua I linked?

Thanks for your help,

The flow rates for Noctua translate to 37, 45, 54 CFM. Presumably the LNA and ULNA are inline voltage controls that reduce the fan speed. That does give options of 12 and 16 dB at the lowest 2 speeds. These are potentially quieter with the ULNA adapter but still have the option for a higher flow at the same noise level as the quietest Scythe. Scythe is a better-known brand. I would be inclined to go for the Noctua - a few dollars more.
 
@ Nanobyte and salvage-this, thanks for the response. According to the PCCG description, LNA means Low Noise Adapter and ULNA means Ultra Low Noise Adapter. So would I be able to control the fan speed with a program or would I have to buy something else to do that?

Thanks,

Out of those two I would choose the Scythe as it has a bit more airflow than your minimum. The 10dB seems a bit optimistic. Very quiet but shakes your house to its foundations! Not much other info on the linked page but the others in that series have double ball bearings which is good.
 
Okay, I think I'll save up for the Noctuas and use it with the Low Noise Adapter, 16dB will be inaudible :)

Thanks for the help,

I don't follow your logic. While I voiced some skepticism about the 10dB, the 800rpm Scythe fans look the better buy. For some reason that particular fan/speed combo is not listed at the stores I normal browse so I could not quickly find any further info.
