Everything (seemingly) powers on but screen is black in Troubleshooting Posted June 25, 2018 1 hour ago, Get Booda said: Yeah, they totally would. At 100% speed usually. Hmm. The CPU fan seems to be going pretty fast, but the GPU fan I'm not so sure. It's only an RX 560 so the fan probably isn't that fast to begin with but I'm a little skeptical. Maybe it is running as some other default fan speed that is less than 100%?
