So I am using an AMD Athlon ii X2 240 in my server and its in a shed. What would the lowest temp the CPU should be ran at. It is 56 Fahrenheit right now out side and the CPU is idle at 17 degrees Celsius. The lowest it has reached in the past week is 6 degrees Celsius. Then it averages 14.4 Degrees Celsius. Is that good or should I move it inside to a climate controlled environment.
