@myronnl sorry you're having issues, have you managed to sort it? This now feels like so long ago that I made this video/guide, and I stopped sim raci...

@markspurrell How frustrating, hope the next board sorts it 👍

@markspurrell How are you trying to test them, if it's by clicking test in Simhub, you have to click test several times very quickly for it to work. H...

@neil_1980 glad you kind of got it working. I found with mine that the fans would cut in and out and ramp up/down, it was due to the minimum force/pow...

@r-v sorry for the slow reply, so different fans have a different starting voltage/power requirement, it is worth checking if the details are known fo...
