80mm case fans - quietest?

[nick_lerwill]

i need about 3 to 5 80mm case fans and i need them to be very powerful and most importantly quiet as you know 5 fans will build up a lot of noise so can anyone recommend the best ones around. everyone here seems to love the akasa ambers but they don't seem to have the best air flow

the 'Thermaltake A1780 Silent Cat Fan 80mm' look descent does anyone know what the air flow is on the 'Thermaltake A1910 Thunderblade 80mm Blue LED Fan'

80mm fans are noisy suckers generally. I've got 2 delta fans in my case (1x80mm , 1x120mm) + 2 generic 80mm fans and it really is too loud. I'd recommend comparing the cfms of the different fans, picking one that has a medium airflow, and then 7volting it. 5 80mm fans that push a lot of air will be pretty ridiculous imo
