View Full Version : new delta 80mm fans

maybe this has been the case for quite a while...but i just noticed that delta seems to have changed their fan designs....now the 69cfm isn't available anymore...instead there's these 60cfm 3-blade fans...apart from looking wierd i'm guessing having 3 blades reduces turbulence, therefore, noise? these new 60cfm fams are rated at 45db...which is noticeably quiter than the old 48db delta:afro:

any comments?

Since I haven't tried the new design yet, I'll reserve judgement. :)

I would have thought that fewer blades would have reduced the available airflow :?:

yes, although there are only 3 blades, each blade is much wider than normal and the total fin area probably is about the same as a normal fan;)
