Glad this post is here - reason i came here is does anyone know if i am better off having the top exhaust fan running off of the hardcano 9 (always at full speed) or would i be better off running it off of the Antec True550 w psu (fan plug). I know the psu adjusts the fan speed i think. But im not sure of the fan speed at any setting for the hardcano 9. If i knew which always runs faster i think i would use it. So bottom line is - does anyone know the max fan speed for the hardcano 9?
