Sounds dumb but I just had this computer built almost a month ago, and I don't think the GPU's fan ever turned on. Somewhere I read that the gpu fan only turns on at high temperatures or something. It is a MSI R9 390 8G with ASRock z97 Extreme4 Motherboard. Other than that, everything is running smoothly, I just don't want something to burn out by not having the fans running. Is there a way to check or turn it on. Thanks.
