Hi to all......Does anybody know if such a fan exists.....or am i living in a dream world?.......If the answers no, whats the nearest spec 80mm fan?
I know about Silenx (SilenX 80mm 14 dBA Fan= 28 CFM official spec)....but ive read on a couple of forum sites that there not all there cracked up to be.

Welcome to SPCR!

The basic (paper based) stats of 80mm fans says you drop below 20dB(A) at round 25cfm. Except as a paper based exercise it is pretty futile hence efforts here to describe what the sound is really like. (Some fans that are genuinely good on paper are horrific in reality due to the nature of their noise - clicks, rubs or other stuff that may be fine to you but irritates me. Or vice versa.) Try get 2 or more fans from the recommended list and you will start to work out what your needs/wants/aggravations are!

As you have already read you can try chase the folks whose marketing exceeds their engineering. Silenx & Thermaltake tend to dominate the Hall of Horrors in this category.

The Yate Loon D80SL-12 is rated for 25dB(A) and 43 cubic metres per hour (?). Dunoo how to translate that to 20dB and CFM.

YL D80SL-12

It's pretty much the quietest 80mm fan I know of.

Thanks for all your replys........Ive orderd an 80mm vantec stealth...I thought the specs of 21db-27cfm was a good compromise....Panaflo and nexus (from what ive read), are highly respected fans... I guess the 27cfm won me over in the end.

FYI, Vantec Stealth is one of the "brands to avoid" listed in the sticky Quieting a PC, and SPCR... in a nutshell.

I bought some Vantec Stealth fans when I began my silencing addiction. That was probably before I found SPCR. They seemed quiet to me. But I had other issues at the time. Now when I listen to them, I cringe.

Unfortunately, it's hard to buy a fan based on specs. Even 2 fans that are rated for the same airflow and noise could sound quite different. One might make 25dB of smooth whooshing sounds. While another might make 25dB of clicking/whining sounds and be much more annoying.

You are better off with cooler master or yate loons. maybe the new stealth fans are better. the ones I bought a year ago were not loud, but not silent. but they did not adjust at all with a PWM controller.

Well........ i got the vantec stealth through the door....I got it all trimmed up and fitted to my xbox...I think its close to quiet...but that opinion, is from somebody that tollerates a vantec tornado, in the background, every day.
