Puttness Posted December 4, 2023 Share Posted December 4, 2023 I'm going to be building in a 5000X for my new PC this Christmas and I was curious about the PWM repeater included. I have 10 fans, however 7 of them are AF120s and only 3 are SP120s (included with the case). 3 of the AF120s are coming with my H150i Elite Capellix XT, so I will have the commander core from the AIO + the included repeater for my fans. This is enough for my 10 fans of course, but what I am curious about is whether it is safe to put an AF120 and SP120 on the same repeater. Because the AF120 has a vastly higher max RPM compared to the SP120. This has me very stumped. I want to avoid getting another Commander Core, only if absolutely necessary. When you send a PWM signal to the repeater would the SP120s max out at their top RPM while the AF120s ramp up further to their higher max? Or would the SP120s end up limiting the AF120 max RPM? Or last scenario, would it make the SP120s spin at the same RPM as the AF120s and possibly damage them? I'm putting 3 AFs on the front panel, moving the 3 stock SPs to the side, AIO mounted on the top with 3 AFs exhausting, and one last AF on rear exhaust.

Puttness Posted December 4, 2023 Author Share Posted December 4, 2023 So I actually just researched this myself (I shoulda done that first, doh!) and figured out that there will be no issues. As the PWM just controls the duty cycle and is measured in percentage. So if I send an 80% signal then the fans will both run at 80% of their respective max RPMs. I am very glad to hear this, it was kinda frustrating when I didn't know what question to ask. Nobody else has asked this question before regarding the 5000X, as far as I could find. Link to comment Share on other sites More sharing options...
