whats a good brand for computer case fans? im looking at cool masters, rocket fish, masscool, antec.Fans do not have brand names that are household words.
Maybe we could take a survey.
To be serious, get an electronics parts catalog and see what hobbyists and  Engineers buy.
Here is my FAVORITE:

The have a catalog of both surplus and brand name inventories.  The prices are either the same or lower that others.
But if you only want new  industrial grade PRODUCTS try:
http://www.jameco.com/
The above company doers international shipping and offers discounts for quantity purchase. The also have a downloadable Catalog.
Better on-line  retailers will sell fans from reputable companies.

As for brand names of fans, I don't remember any.It really DEPENDS what you're looking for - airflow?  Static pressure?  Low noise?  What size?  And how much do you want to spend?

Yate Loons are cheap, decent quality, and they're offered in the common 120mm and 140mm sizes from 800rpm (super slow and silent) to silly high rpm (lots of airflow, very noisy) so I often recommend these as a general option.  They're quite hard to beat unless you're looking for something specific and are prepared to pay a little more for it.  I use Sharkoon fans (rebadged Zawards) which are a little pricier but arguably perform better, again they're not suitable for everyone.  I also use a lot of San Aces, which are industrial grade 38mm THICK fans (as opposed to the standard 25mm thickness) which are LOUD at full speed and push a lot of air.
