JG Luxe Posted February 19, 2019 Share Posted February 19, 2019 Is there a difference between the 2 fans other than the RGB capability? I just got a Corsair 280X that has (2) LL120's and I purchased 4 ML120 Pro RGB fans (2 to replace the fans that come on the H100 and 2 for the bottom of the case) Decided to add an extra fan in the 2nd compartment of the 280X just to get some more air flowing (went with a regular ML120) and I have all the fans plugged into the same fan hub, Without the ML120 it's like a slight hum really quiet, with the ML120 its way louder.. I also just searched it on the product page while typing this and I just realize the ML120 Pro is 37db and the ML120 Pro RGB is 25db So my question again, What's the difference between the 2 (well, 3 fans) other than the LED's?

c-attack Posted February 19, 2019 Share Posted February 19, 2019 Because the ML120 maxes at 2400 rpm and the ML120-RGB tops out at 1600 rpm. Otherwise the same blade, so if you cut the speed down to match, the sound levels should as well. Link to comment Share on other sites More sharing options...

They're all PWM and are connected to a PWM fan hub, which means they should've all been at the same speed, shouldn't they? Link to comment Share on other sites More sharing options...
c-attack Posted February 19, 2019 Share Posted February 19, 2019 If the PWM controller effectively functions on % of maximum, then you will see different speeds for fans with different limits. Most of these PWM hubs need a control source and that is usually a line back to a motherboard PWM header. Those are almost always % control. Quick solution is to move it off the set to another PWM header. If that is not possible, then you may want to look at alternatives. A 2400 rpm fan is overkill for your purpose. A nice 800 rpm PWM fan will quietly do what’s needed. Link to comment Share on other sites More sharing options...

I don't feel like spending more money on a different fan as I just bought the case, 4 ML120 Pro RGBs, the ML120 Pro, a bunch of new extensions for the PSU and the controller itself lol. Thanks for the help! Link to comment Share on other sites More sharing options...
