So I was changing the case fans, after I put everything back together, I forgot to plug in the power for the GPU. I turned the pc on and I saw the white LED on GPU power port lid up and heard the fan spins like crazy (I don’t know if it was the CPU fan or the GPU fans), I panicked and immediately turned off the power supply.
Everything happened in less than 2 seconds, I’ve run some stress tests and gamed for a few hours and nothing bad happened (yet?) so I assumed everything is still fine (for now?).
What happens if I had left it on like that for longer? And why did the fan ram up like that?
“what happens when I don’t plug thing in?”
Thing does not work.
Next question.
But loud fan noises are scary
I’d guess the concern was something to the tune of “if it’s only getting mb power, will it somehow dangerously undervolt or be otherwise damaged?”
