How reliable is the program lm-sensors in Linux? When I run watch sensors, I see large skips of temperature, as high as 10 degrees Celsius within the refresh interval of 2 seconds. The images below show this, with two screenshots taken 2 seconds apart, with Core 1 jumping 8 degrees down between those.
