Okay, couple things to unpack:
The max temp was 75 degrees C for the CPU, and 85 degrees C for the GPU
My SSD has Windows 10 OS, minecraft, Overwatch, and Team Fortress 2 on it, nothing else, this shouldn't matter though as this lag spike thing happens on ANY game I play, it has even happened while watching Youtube on Chrome.
My SSD has 319 GB free, out of 464 GB.
