Need to find some quiet fans.

post #1 of 6
Thread Starter 
I'm getting ready to put a system together in a rather old case of mine. It currently has:
1x Side LED Fan (80MM, I believe)
1x 120MM_Space_ on the back, above PCI slots.
1x Front 80MM Plain, brushless Fan. There is a honeycomb area in front of this fan, then a 3/4" gap for it to get air from, directly UNDER the front faceplate cover. This fan is basically for cooling the Hard Drive area.

I would really like to make this a quiet system, to the point where it's barely noticeable that it is on. I know that with this cheaply made case, some things can't be possible, however I think if I correctly correlate and place these fans that are quiet in the spaces, it will be a nice quiet system...however, I will in addition probably have a 120MM fan on the GPU, unknown noise level...and the PSU fan. So I don't think the fans will have to be under 15dB...?

Also, feel free to suggest any decent cases to me that are spiffy looking and that can be had for a decent price....I may end up just having an entirely different case later on.

First: What CPU, CPU cooler, GPU, and GPU cooler do you have? What is your definition of silence? What speeds are your current fans running at and how loud do you think they are?

The reason I'm asking is that some people think 1500 RPM 120mm fans are quiet, while I wouldn't want to be in a room with such a fan without some music to drown out the noise.

And before the n00bz start recommending you fans: dB ratings on fans are almost always false advertising. If a fan says 90 CFM @ <20 dB, it's not true.

AMD Phenom II 955 - Stock Cooler

Likely 1,000-2,000...no way to tell...just typical cheap case fans.

I was using NF-P12s in my rig, but at full speed they're still noisy. They undervolt really well though. At 5V, you'd just about know they're on.

I've sinced moved to Akasa Apaches. Slightly quieter at the low end than the Noctuas, but quite a bit quieter at full tilt. They also have much better static pressure, if you're ever going to get into a quiet WC setup, those'd be the fans to use.

There are no "silent" fans

Turn them down with a fan controller, or manually put them on 3 or 5 volt.

Standard is 12 volt.
