SF2 SUCKS. ok tbf it is good for some things, and alot of people like it. but also a lot of people hate it.
If you're interested in noise at all then its a bad choice at whatever performance. The motor is built for high speed and fights itself at low speeds, add in the fin design and its comparatively very noisy at low to medium RPM. It does high RPM quite well but is still noisier and lower quality than equivalent performance fans from higher quality manufacturers. The thermister is also really pants.
But if you want a fan for low speeds, theres a bunch of fans that do it much better. If you want a fan that does a range in the middle, theres a few fans (esp. ys-tech adjustable) that does it a lot better. If you want variable huge airflow fan the SF2 is ok but there is still better, though most need a seperate rheostat.
The good points of the fan is it does come with a working rheostat, and does do a lot of airflow for a 80mm, reasonably priced fan. If you put a lot of value on being able to have mega airflow while also being able to cut the airflow down to the equivalent of a shabby medi-low rpm fan, SF2 is probably the best fan for this. If you dont need to be able to go from one extreme to the other (and very few people need 75cfm, even fewer that only sometimes need 75 yet sometimes 25), there's plenty of better choices - imho anyway.
Just IMHO. Plenty seem to agree, plenty disagree. Probably both are right, it just depends on POV.
