Summary: Decent airflow and very quiet fan even on maximum, however it only earnt 4/5 because the LED's are pretty dim. i have it alongside a Aerocool Evil Sharkfin fan and it looks mediocre in comaprison.
But like i said performance wise this is great
Summary: Ive used many case fans over the years and were as some are advertised as "quiet" they dont allways turn out to be
however the bitfenix spectre led 120mm fans are quiet and do a sterling job of moving alot of air
the led,s are not too bad...
