I would wait for the HR02 macho, which is a $39.95 version, that already comes with the TY140 fan, this is to me at that price, the best deal out there, the fan can be brought down to 700rpm (at least in my build
i did controlled by the mobo), the fan is very good (imho).
The Silver Arrow would be the best in temps, but this is a high end cpu cooler, more oriented for OCers, it uses 2 fans, to me a 2100 is an overkill the HR02, a silver arrow would be even more. The more fans you have the more noisy it will become, so i would try a single fan over dual, unless you were aiming into OCing.
The Scythe Gentle typhoons are to me the best fans for performance, but they have their own signature, not all like them, i see more good comments regarding slipstreams here than GT. The Mugen 3
comes with Slipstream PWM fan included, that can be lower to 300rpm, where it should be inaudible, and since the i3 shouldnt go high either, this imo is more than enough. But you will have to check your mobo to see if it can control the fans. I would also consider swaping the case fans that come with Mini for Scythe SY1225SL12LM-P 120mm Case Fan
(PWM 200/1300rpm) and control them with the mobo (if you mobo can via bios/software).
