I did have 4x 80mm thermal fans i bought years n years n years ago but I cant remember the brand (2 are still in use in my back up pc)
the only few 80mm fans i can think of (if not the Akasa ones with LEDs that go at 3000+ RPM) is the Akasa Amber series fans. - but they have a lower RPM & also make a bit less noise then the fan that just died on you.
ermmm........Artic Cooling make 80mm fans too
this might be to your liking
but unfortunately its not as good as the one that died on you. but the words 80mm + silence dont fit in the same sentance.
Scythe KAMA FLEX's have had many good reviews - but they are noisey & thats where your fan controller will come into good use.
sorry I cant help further.
