E480 here. I didn't see unusual CPU/IO. Did you let it settle for a day? Noise: Lenovo doesn't enable Speed Shift and the firmware provided fan control is shit.

E480 here. I didn't see unusual CPU/IO. Did you let it settle for a day? Noise: Lenovo doesn't enable Speed Shift and the firmware provided fan control is shit. If you want to fix it: Get a tool like tpfan and tweak the fans. Get ThrottleStop to enable Speed Shift and undervolt a bit. - Noise was pretty much fine on Linux out of the box. I just undervolted because why not.
