I have a new Windows 10 gaming machine I had built for me back in July. It's working great except for the fan is constantly rev'ing up and down, but I'm not doing any intensive tasks. I didn't have this problem in my previous Windows 7 machine or even my Windows XP machine. There's nothing in the task manager that is really being pegged, cpu-wise, when this happens, we're talking Firefox goes up to maybe 3%, for example. I have: AMD Ryzen 5 1600 six core processor (no huge spikes there when fan ramps up) 16 gb of ram (currently 18% of that is being used via the task manager) No networks spikes or anything, I get the fan speed variation doing simple things like following a hyperlink in a browser. I also turned off pretty much everything in privacy and notifications just to eliminate any unwanted network traffic going on in the background. I did some googling and some people have had the problem with multiple video card drivers installed, but via device manager I only see my GeForce GTX 1080 under display adapters. Anyone have any ideas how I can normalize my fan, the constant rev'ing up and down is really annoying.
