Ok, i'm looking at getting a few blue LED fans (Three or four), i'm looking at the £6 CoolerMaster ones.
They are 25 dBa each according to the websites they're on, but how loud ill they be togethe if i am running three or four, and if i get myself a rheobus will i be able to slow them down at night to almost still so they will be even more quiet?
Thanks.
