quietest 120mm fan

[gychang]

with the proper connector (4 large prong), need 2. Where is the best place to order along with the fan guard.

2cooltek is good:
This is the quietest, but you have to realize that less noise = less performance.

He also has a nice selection of grills.

Panaflow fans are the quiestest fans available. They have pretty good output for their db rating as well.

I have two 120 mm and 1 90 mm panaflow fans and the three combined are much quieter than the golden orb HSF.
