I have a Dual-X sapphire R9 200 series 4gb, I bought the entire rig secondhand. The fans didnt work when I bought it so I had new fans and heat sinks put in. Its been a couple months and out of the blue they stop working again. At first they might spin on every other cpl boots, now not at all. They don't kick on during high load or anything. Just stil, MSI thinks they are running, it'll change the speeds according to my curve, but the fans won't spin at all. Tried cleaning my drivers and starting from scratch with new drivers, checking the power plugs.... idk whats going on. sry if I posted in the wrong place, im new here.
