    Introduction
    From their release, there has been alot of skepticism about these fans and their ratings. The models which i am reviewing today are the:

    • 110 cfm / 37 dbA
    • 88 cfm / 33 dbA
    (The 110cfm model runs at 1900 rpm and the 88 cfm runs at 1600)

    Unfortunately, i don't have a wind speed recorder so i cannot verify the cfm specifications, but i can verify it through other means:D

    The Review
    Firstly, on the box Scythe quote that they are able to get such high CFM ratings because:

    "By reducing the dimension of the center hub and enlarging the blade surface area, high airflow is generated at low RPM

    I can accept this fact. The fan blades are each 4.2cm long and at the widest point, they are 1.9cm wide. The blades look very efficient and are very high quality (you cannot see any plastic molding marks).

    Through some amazing maths, i will try justify the claims made by scythe.

    The whole diameter of the fan is 11.7 cm.

    This means that the area of the fan is about 108cm squared.

    The diameter of the centre is 3.3 cm.

    This makes the area of the centre 8.6cm squared.

    Finally, this means that the centre takes up 8% of the total fan rotational area. Pretty nifty :D

    The total area of the blades is about 83cm squared. This means there is about 16.4cm of free space for air to travel. Finally, this means that the blades occupy 84% of the total area available. Very cool :leet:

    The Noise
    I can confirm that these fans are quieter than a Antec Tri Cool LED on high and medium. The sound it makes is a low humming one, which is not unpleasant on the ear. I would say that the rating of 37dba is dead accurate, no more no less. These fans really have to be heard to be believed :D

    Performance
    I am mounting my Thermalright Ultra 120 Extreme tomorrow with these two fans in push pull. Will add figures when i get them :D

    Conclusion
    These fans are highly recommended as case fans or CPU fans. The claims which scythe make, in my testings, appear to be true. I am a believer that Scythe achieve such a high cfm to dba ratio due to the lower profile of the centre and the larger, broader fan blades. As stated above, the fan's performance will be evaluated by my Thermalright.

    Hope this helps,

    Goat

    Good work goat :)

    how do you think 4 of the 110cfm would sound like?

    and, is your computer on the floor or the desk?

    Um, wack a big cable tie around the top and bottom??

    Its relatively easy, use some creativity! Perhaps use industrial rubber bands or if your not sure, just buy extra fan clips.

    Yeah I'm thinking of waiting for the higher powered ones to come to AUS.

    I'd prob be interested in perhaps buying 1 or 2 if you guys were to do a bulk order, but then it'd probably be awkward to get everyone to pick them up. :p
