The Silent version’s fan quietly and efficiently brings the temperature down. The low decibel (19dB), high volume (30.8 CFM) fan is 80mmx80mmx25mm and runs at an ultra-quiet speed of 1800 RPM.I'm not sure about the pricing but it shouldn't be too expensive.
Unlike the Silent version of this series, the PWM version has an 80mm×80mm×25mm adjustable speed fan which brings the temperature down according to your needs, The fan ranges in speed from 800~3200RPM, with a maximum volume throughput of 51.3CFM. The Fan puts out 34dB maximum at full revolutions. The entire heatsink (both versions) keeps a relatively low profile and only weighs in at 373grams (Well within Intel’s safe CPU specification of 550 grams for a CPU cooler).
