Hi there !! I opened my MDD dual 1.25, and removed the heat sink to place a fan at the back of the heat sink, to force the heat out of the case. I placed the heat sink back, booted a couple of times, everything was fine, but the fan was making noise. I removed every screw of the heat sink, except one, pushed the heatsink on the side, add another screw to the fan, so it'll be more stable. I replaced the heatsink, tryed to booot, and then, nothing happened... The computer starts, no chime sound, and then, about 10 seconds later, the CPU FAN starts to spin at full speed.... Anyone have an idea of what appened ? Can i do something about that ? Is removing the heatsink voiding the warranty ?? thanks !
