chibi- Posted November 27, 2019 Share Posted November 27, 2019 Hi there, Is the listed amps on the spec sheets for both ML120 and ML140 Pro fans the startup power draw? Or is that just the operating power draw? Does anyone have the startup power draw info? If so, please share. Thank you! Link to comment Share on other sites More sharing options...
DevBiker Posted November 27, 2019 Share Posted November 27, 2019 That's the max power draw. Typically, they will use much less. However, that's the guideline that you should follow when planning power usage. What is it, specifically, that you are planning? Link to comment Share on other sites More sharing options...

My case has 6 ML140 fans, to be safe I'd limit them to two per mobo fan header (1A). Link to comment Share on other sites More sharing options...
c-attack Posted November 28, 2019 Share Posted November 28, 2019 You're more than fine at ~0.20A per fan. Since they are PWM motors, there shouldn't really be a huge power on spike and I can't recall a single instance of blown headers or fan controllers with ML Pro fans. I've been running triples for a long time off a 1A header. Link to comment Share on other sites More sharing options...
