Review on Technologies 200Mm Cooling Sleeved RF FZ20S W1 by Matthew Maggot

Was placed as a front air intake on the NZXT Source 530 in hopes of reducing overall noise levels. Airflow is about the same as the two 140s it replaced and noise is moderately reduced, although I have to keep it at 50% (450 rpm) - the higher it gets, the louder it gets in my case . Unfortunately the NZXT came with a sleeve bearing, but this is a budget fan and you get what you pay for.
