WebDec 4, 2024 · DC fans are more commonly used as case fans or in situations where the system is likely to need to maintain 100% fan speed, such as in the case of a 24/7 server. PWM fans are more valuable if noise is a significant concern or if you're looking … WebYou can drive PWM fans with DC control - so just set the header to DC, and you should be good. You loose some low rpm-range on the PWM fans by doing this. The Aquacomputer Aquaero can control both PWM and DC fans (has 4 fan headers). But it's probably cheaper to just switch the DC fans to PWM fans. ;) 2 m_kitanin • 2 yr. ago Thank you!

Pwm is for case fans where you want the bios to determine the fan rpms based on cpu loads and/or system temps. You want liquid cooler pumps to run at full speed at all times. That's informative, thanks. For the pump, smart fan mode on or off?
