So I just upgraded my PC. My new parts are: i5 7600k 16GB Corsair DDR4 MSI z270-a PRO GTX 1070 from Gigabyte And I'm running Windows 10 Pro Here's the problem. Ever since I swapped parts, my graphics card's fan speed will not lower from whatever max RPM it hits (sometimes it'll be like 60%, and when I was testing stuff I'd change it to 100%). I've tried EVGA Precision, MSI afterburner, and Gigabytes own Engine thing that I forget the name, and basically none of them can lower the fan speed. I've tried reseating the GPU, updating the GPU BIOS, updating the Mobo BIOS, doing a fresh driver install with DDU, and doing a fresh Windows install. Nothing has changed. I'm going to try putting the GPU in the other PCI-E slot, but before I do I want to get some input from anyone else. Anyone have any ideas?
