Reliable (?) Fan database?

Just got pointed at this site from another forum I'm on ...

http://gizzo.8m.com/fans/fan120.html

... since you chaps have got the "real world" experience - how reliable is the info on this site? If it's any good, it might make life a lot easier?

.

Also, as I guess, this site is somewhat "skewed" for "our" purposes, as (I guess) the site assumes that fans run at full 12V. Whereas most (certainl I) intend to (if not already do) undervolt the fans.

Well - hope it is a helpful bit at any rate

The info on that database is an OK starting point.
The downside is that it only tells you the numbers given by the manufacturer, and different manufacturers measure slightly different. Also they normally don't take vibrations etc into account.
You can use that database to find a few good candidate fans and then search the SPRC forums for more info on those fans. There are a few comparisons between the good fans in each category.

I believe that MikeC is doing a great test of fans (60mm to 120mm) at the moment. Once that test is finished we will have a lot more complete and objective data than any of us can provide.
