Hey folks, i've just setup my new motherboard (intel DX58SO) with it's included 40mm fan for the IOH (what is this anyhow?) ...

the fan is simply too loud, and I hate the bright blue LED it includes.

So i'm looking at a Scythe Mini Kaze Ultra 40MM Silent Fan 20MM 3500RPM 4.8CFM 19.5DBA 2PIN 3PIN

Anyone out there used one of these? Are they quiet? Ive never used a Scythe fan... let alone a 40mm one!
 
I have both versions, the 20mm and 10mm and they are very quiet for how small they are... and push a decent amount of air... again for how small they are.

Not silent, but quiet in comparison to most whiny/noisy 40mm fans.
 
Haven't compared them side by side, but I'd assume the 10mm would be louder...
 
Ah, forget the Mini-Kaze and just get one of these Delta's. :p

But to answer your question, the 20mm Kaze will be louder, I have never used one of the 20mm only the 10, nice little fans, but for me still needs to be undervolted.
 
... woudlnt the thicker of the two fans be quieter? doesnt have to spin so fast to move same amount of air...

Thicker does not mean more airflow at lower RPM, it means higher static pressure, which most of the time you have to give up some noise for, you also have to look at the spec and see that they both have the same speed rating, the mfg them selves even list the 20mm as louder....Not really sure what you are looking for.

You take a given fan like say a 120x25mm fan and other just like it but 38mm, the 38mm will be louder, the tone profile might change, that is have a deeper tone which might (though not always, depending on the sound quality) be less intrusive on the human ear. Think of it like a ceiling fans hum, or a mosquito flying by your ear, the ceiling fan is going to have a much louder sound (in terms of dB), but which would be more annoying?
 
nice analogy ;)

thanks for the explanation.

These fans are so cheap, i think i'll order both, see what they sound / perform like.
 
I put the 20mm thick SY124020Ls on my Abit Fatal1ty AN9 32X. They were much quieter than stock and still kept things cool.

FYI, it's a 2-pin fan with a 3-pin adapter, so no RPM-sensing. I ended up cutting the 2-pin plug off and hooking it right up to a 3-pin, since the wires only needed to be a couple inches long for my board. The adapters added a lot of extra clutter in my situation.

I know it's crazy, crazy that they are a bunch of pussies that didn't go for 10k rpm. :p

might try a maglev fan. they tend to produce less noise. I use one a few years ago on a mobo chipset and was impressed:

Maglev is nothing great, still comes down to the fan over all, I used some of the Sunon 40mm fans, they are ok, but at full speed are sure as hell loud.
