Hummm......After mods, different fans, masses of wires, cables, different sized cards, maybe a poorly designed case, who knows what temperatures will be at different points. You all should know by now that all internal components last longer at cooler temps.
I use a DigitalDoc5 that monitors temps at eight different points by the use of separate sensors on long wires. After hooking up all the sensors, I discovered several hot spots/components. Easy mods lowered temps in the hot areas.....I'm sold on a DD5.
