Just clarifying that I'm NOT using an adapter. I'm using the full
RPM range with PWM signal. If I want this thing can ramp up to max RPM of 2000 RPM (although I never max out my system really, I never bench). It's stated as minimum RPM of 800 but I can show you 0 RPM showing on my HWinfo. As I mentioned, in this case, they have no problem going from 0 RPM to XXXX RPM and back to 0 RPM and doing it all again automatically.
They're not fixed RPM unless you use an adaptor: http://www.coolermaster.com/cooling/case-fan/jetflo-120/
Tangent but about the LED and current flow, I know already and THAT'S exactly why I LOVE these fans. It's basically a design flaw because they changed that in newer models (CoolerMaster basically ended the JetFlo line and created the average MasterCase line) and every other LED fan out there with lights in the motor section offer full brightness at all times. These are the only fans that can basically act as an "activity" indicator for me. It's a huge plus to me when I have parts with LEDs and actually have a bit more to do than just bling/flashiness.
Also, I'm not saying one has to use these fans, it was just a suggestion and I'm just showing proof that indeed possible, at least PWM fans, can go from 0 RPM to XXXX RPM and back without problems.Edited by TheBloodEagle - 4/24/17 at 5:53pm
