Subject: What is the maximum CPU fan wattage supported?
Posted: 28 Jun 2017 at 1:32am
On the existing Asrock X370 boards, the high amp CPU and Chassis Optional/Water Pump Fan headers support 1.5A (18w) and all of the Asrock AM4 boards have a 1A (12w) CPU fan header. That Delta is not a PWM fan anyways, so you would need to use a manual fan controller that can handle 36W on each port or just run it at full power off the molex directly to your PSU. As an owner of the 92mm Vantec Tornado (made by Delta) in the 90's I can tell you you do not want this thing running above 40% for the sake of your sanity. If you really feel that you need 100+CFM from a 92mm fan I would suggest the PWM Delta below that you can run with a custom fan curve off of the 1A CPU header or the high amp header if the X370 ITX has has one (these specs are available yet AFAIK).
