Would like to see Yate Loon 120mm fan in the comparison, recently it shows up as a very good competitor in the silent fan market :D

Hey Hans, thank you for the suggestion, I've seen that name pop up also in different fora; do they have a specific model which is most popular?

@maniak: thanks!

I belive the Orange Yate Loon is the most common out there, and Nexus range are top end rebranded Yate Loon, higher RPM i believe, so taking a Nexus and speculate the noise/speed .. from it would be easier, as I had nightmare finding a Yate Loon in the UK.

Forgot the spec:

This is the orange Yate Loon
1350 RPM @ 12V, 47 CFM, 28dB


PS: the black one are also commonly found in PSU i think, Seasonic ?

after reading some stuff on spcr if found out that nexus fans are actually special yate loon's

the normal yate loon has the specs Hans mentions, the nexus fans use the same bearing and rotor but only runs @ 1000 rpm

so normally if you undervolt a yate loon it will be equally silent as a yate loon

to those who claims some fan make "weird noises" at lower voltages.. are you holding these fan at 3mm from your ears? because at that distance I too can make out the motor noise (and not just the wind blowing noise).

but at 5-10cm from my ear that motor sound is very very silent and at 20-30cm you can not hear it. How close are you sitting next to such fan to find these noises disturbing? :)

SmartSensor SL4001A Where to find?
 

I did a google for the smartsensor mentioned in the article and came up with nothing. Where can this device be obtained?

I got it off eBay from a wholesale in China;

maybe you are just getting old :^D
