Mounted on top of my body, it is managed by my motherboard and calibrated into the bios. Very good build quality, though I saw only by Noctua before, I find it even quieter. Easy to assemble with these silent-block and nipples replacing the screws. It honors my case LIAN LI PC-Z60B. Regarding the cooler, I by cons opted for a Cougar VORTEX V12HP CF-regulated PWM (high efficiency), that blows very hard with well over noise ... I recommend it unreservedly Be Quiet, housing assembly. RS
