| Summer time has an extra cute feature for fastidious PC owners. There's an ambient temperature point that once exceeded, makes box and processor temps rise in a non-linear manner. After this "knee" is exceeded, the temperatures of case and processor are again linear with the ambient, or room temperature. HOWEVER, the case's interior picked up a lovely jump in temperature of say 4C "out of nowhere."
For the sake of argument, let's say that this "Magic ambient temperature value" is 73 degrees F/23 degrees C. At 22C, the case's interior is 5C hotter than room temperature. Presto, chango, at 23C room temperature, it's 9C hotter inside the case than the ambient air temperature. This new relationship of case interior temp to room temp is now "normal." The new linear relationship holds true as the room and case temps keep on rising. AFAIK. Maybe there is another "knee" at higher temperature. I kinda don't want to find out!
I assume that simple heat saturation impedes the ability of the case to transfer heat to the outside. Perhaps this delightful bonus of 4C can be put down to entropy.
Anyone else notice this?
