120mm Fan Roundup

jmke · 10th January 2006, 01:36

We test 6 different fans from Titan, Acousti, Arctic Cooling, Coolink, Antec and Papst. Using a Scythe Ninja in a closed case we´re set to find out which fan will act as the best heat exhaust.

Other fans sugested so far that we're considering to include in our next part of the roundup:
- Nexus D12SL-12
- Orange Yate Loon
- Vantec Stealth
- Silverstone FM121 & FM122

The lower the temp the higher CFM and noise; with a single exception AC yielding a 3-dBA differential (40 v/s 37). At this threshold it may not be noticeable

Is it just me or was the AC fan the daddy at 7.5V?

Which leads to the question, why don't they deliver it already at this speed? It could kill the Papst GLL at this speed.

Similar things can be observed with the Freezer PRO, which has a brilliant motor, but without turning it down you can hear the air moving.

I bought me a Papst 4412 FGL a few days ago.

26 dB - 94m³/h

Quite quiet and a nice airflow.

After reading the spcr forums, i've bought nexus fans (http://www.nexustek.nl/) maybe u can get a sample of it to test it. (If you didn't life that far from here I would lend u my fan)

also on the spcr forums I read the the noiseblocker fans begins to make a clicking sound when not getting 12 volt, it had something to do with the ball bearing used.

Where did u get the Ultra-Soft Fan Mounts from acousti, because i'm looking for them.

Acousti send them with their fan, but they are optional, check their website for reseller list;

I'll check up on the Nexus fans, what model(s) are you referring to?

the coolink fan (the former noiseblocker) did not sound weird at <12v, but do you mean that they start clicking directly.. or after a long period of use?

PWM fan controllers might be the solution (like the mCubed fan controller) but this method does not work well with all fans, they have an extra small device to convert the digital PWM to analog. check the webnews for mCubed I posted a link to SPCR where somebody looked in detail at the this PWM combo for fan control

quote from spcr (http://forums.silentpcreview.com/vie...ker+click ing)

Quote:

The problem is with their designs. The fans are designed to run at 12V fixed. The ball bearings produce minimal noise at that speed and the air output is respectable. The S2 fits a nice spot for a quiet-computing seeker. The blacknoise 120mm fan blows an incredible amount of air for the noise but it's noisy. period. However, most of us here in SPCR run fans at far lower voltages - at which time the the ball bearings start clicking audiably - in inverse volume with the voltage. I've become too used to sleeve bearing fans and can't stand the click of a ball bearing fan.

it seems like undervolting ball bearing fans can produce a clicking sound, but sound is something that is very personal, some people can't stand it some don't hear it...

so clicking will be hearable immediately by reducing voltage? will check again tonight, although I've already had my ear next to do them, no clicking.

btw what Nexus 120mm is good? what product model?

dunno how you can find that antec loud? got one on my CPU and its very silent.

But offcourse I'm the personne with 11 fans from which 2 enermax in my case

jmke · 10th January 2006, 16:28

the Antec is loud compared to other fans (except for Titan). I find the Antec do-able at medium speed, silent at low speed.

it's hearable if you pay attention
