    It has been a while since I've done a review on a simple item such as a fan. This is usually because fans have reached their peak in performance, features, and esthetics. With a little tweaking, Sharkoon has managed to bring such a simple item to its true peak, by creating possibly the quietest 80mm fan on the market.

    It's all well and good to have silent fans but when they don't move much more than 20CFM they aren't very useful to me. It gets pretty hot here in Aus in summer and without some decent case fans a lot of people get crashes.

    haha, 40+! yeah, this year was the hottest in like, 30 years. But it was only 40+ for about a week. Your complaining about nothing, man. Unless you really want to overclock your pc something chronic, it shouldnt worry you, youve got air conditioning dont you?

    Never cared too much 'bout fans. I don't care if they are doing noise, as long as they decently cool the system. I currently use Vantec/Delta/Panflo fans in my rig.

    Vantec stealth or tornados? One is silent the other you can hear from a mile away :) And those deltas are pretty loud too. Most Panaflo are nice and quiet

    Those are good fans...

    I've found the Panflo fans to be the best, in terms of being quiet while moving a significant amount of air. These Silent Eagle fans aren't designed to move much air - just enough to keep the air moving through your case. The faster model 2000 might work as a CPU fan, with the right heatsink such as a Thermalright Si-97 or Si-120. Heatpipe heatsinks (CPU coolers) don't need as much air blowing through them as the old standard copper fin heatsinks.
    Regarding the inability to test these fans, I guess Silverstrand meant he had no way to measure the sound level accurately. Even though I bought a Radio Shack sound level meter a few months ago, I agree it is difficult to measure the sound accurately - too many parameters are not standardized. You can only do it if you have a sample of several fans, and measure them all the same way (same distance from the blades, same voltage applied to the fan, same ambient noise level and temperature, etc. With these particular fans, you might not even get the meter to register a reading - they are that quiet. And how do we measure the cubic feet per minute output of a fan without some type of chamber and some meters? It would be difficult too. :?

    haha man looks like another Benchmark for me to make :Di know!!!... u fill a Chamber with Compressed air...and the other without air... use the Fan as a Vaccum... inbetween the two... and the time is take to move say 10 Cubic Feet was 6 seconds (10 / 6) * 60 = 100 CFM
    sound too technical?

    OR, you could read the companys stated specs and say you tested it yourself :)

    Not my job, as I didn't write this review. Anyway, you might be able to estimate the CFM if you know the rating for two different RPM / CFM settings. It's probably not a linear scale, as nothing is that simple anymore. As a last resort, try Unholy's wacky method.... :ahhhh:

    Yep my Wacky Method. look at the fan CFM, at 4 places for good accuracy.. and get a Formula... most likely not linear... and not Quadratic...
