Hey guys, Im really stressed out because my gpu fans wont spin and some people say it might be because my power supply is only 400W and doesnt give enough power to 'spin the fans', but the gpu does light up and is being recognized and everything. I have a 400w be quiet! 80+ gold power supply combined with my rx 570 4gb gigabyte. All I want is just confirmation that the problem lies within the gpu and not the power supply. Since I bought the gpu 2nd hand from a tech site which I have returned to them so they can test if the fans really dont spin. the rest of my pc on the other hand completely works fine, cpu, HDD, motherboard and all that stuff. I found out about this when my pc randomly turned itself off. I looked my gpu up and I read that the rx 570 has a passive cooling mode so I played some games but my pc still turned off. I downloaded several programs and nothing worked and all the cables are connected. I returned the gpu to them and I hope I just get a new one, but I havent got a response yet since I returned it today. Though, I just want to know that its not because of my power supply.
