Hey, I just made a really interesting observation. So I played around with the fan setting in MSI afterburner and when I set the fan speed to a certain level (it's somewhere ~75-80%), my fan I thought was "burnt out" fan kicks on. The bad part of this is that it tells me that something may be preventing power from being properly delivered to the fan (meaning replacing it is probably useless) but the good part is that I can work around it via pure software. I wonder if this also has something to do with a power save feature, making it a software issue rather than a hardware issue.
EDIT: the magic number is 76% to make the fan kick on, but I can see it "twitching" a bit at 75%.
