i said "pretty much" in-audible, i didn't say this fan is the best thing since the chocolate fire-guard and is so silent that it makes a passive cooler sound like a harley davidson! so shall we just leave at that? I agree a lot of manufacturer's claim there fans don't perform as they claim (i for instance bought a thermaltake thunderblade fan, thermaltake claim these push 70cfm and are 17db just lies) but what i was getting at is people's perceptions of noise levels are different!

different they are, but ~35dba isnt quiet in anybodys book. also that fan is not quiet in any sense of the word. Yes i know this because i have one. it's also bundled with the crap venus 12 which i have.

2000 10% RPM at 20C ~
5500 10% RPM at 55C

26.50 CFM at 20C
72.92 CFM at 55C

21 dBA at 2000 RPM
48 dBA at 5500 RPM

in other words, 26.5cfm @21dba, 72,93cfm @38dba. and thats just what they claim, not how bad it actually is. I much prefer my ninja plus' 46.5cfm @23.5dba

i had one, they pretty good and can be used on skinned cpus altho i had a dual storm fan on it going at 3500+rpm

i never said my Ys Tech's were quiet, i just said they aren't annoying and they don't bother me having said that when i'm gaming (as this is what i tend to do mostly, previously at a elite competition level) then i'm not really listening out for my fans! IMO it's all personal preference i know that some of you if you heard my computer would be covering your ears but personally i don't think it's loud by any stretch!

thats not true as thermaltake do a 250mm fan that pushes 70cfm at 15db

No, thats what they say it does.

What it actually does is anyones guess, although it may well be able to push 50cfm silently.
When i said it was impossible i meant its impossible for standard 120mm or 80mm fans. If you make a big enough fan you can move any amount of air at a <20db noise level but its not much use if it won't fit in your case.

actually, it gets to a point where the motor needs to be powerful to drive the blades, and motor noise takes over
