i cant say i love this one as the 140mm. build quality is extraordinary, but it is not that dead quiet fan as the rest of the Be!quiet fans i have. after some try and fail attempts to minimize the sound, the best solution is to put extra rubber washer to take the fan further away from casing. i think that the fan is silent on its own but the sound of the air moving when on high rpm is annoying. well, i minimize that sound with the washers, but still, i expect a bit more. but then again maybe if i did not have the 140mm version i will be not complaining at all.
also note that now i have the case under the table and do not hear them until the fans kick in to higher RPM when my CPU reach 40-50 Celsius range
after some tweaking, i realize that the annoying sound is caused by the case-as there are many options for different size fans. so i cut away all the fastening points i do not use and all its crispy silent now. so i also change to 5 stars now
I bought these to replace the pure wings my case came with as standard, surprisingly the fluid dynamic bearings and blade design do make an audable difference, clean aesthetics and very little sound under heavy load, well done Be Quiet.
