Dynatron Crossflow Blower Quickie Review @ TwistedMods
 

QUOTE:

" This fan is different from others that you normally see, but it is designed for 1U/2U servers. The fan is a bit noisy, but it can keep the air flowing inside your case. The wide area the fan covers is good for general cooling. One thing I was disappointed about is the lack of instructions or mounting hardware, other than that this is a very nice fan that would be a good addition to any case. "
