Hi, misfit, thanks for that. I usually run the temp monitor provided
by Nvidia, and when gaming it never exceeds 61 C. When idle, it is
around 55 C. Seems a bit on the high end, but from experience the GPU
normally tends to run pretty hot. Like I previously said, this has
not been an issue before, so I am not sure why it would be now.
