I bought a used system this spring and my temps seem higher than they should. Especially my GPU temp.
CPU is the AMD Ryzen 2600 stock cooler
GPU is NVIDIA GeForce GTX 1080 Duke
At idle my temps are 46c for the CPU and 60c for the GPU
the GPU fans are off for the most part but spin up for 30 seconds and the temp drops to 57c. and does this periodically.
When gaming the GPU fans ramp up to about 70% and the temp is maintained at around 80c.
Does that seem out of norm at all?
