yes, I did get the critical shutdown. I was getting a bit nervous watching the temp keeping increasing, but the exhaust was not even warming up at all. So, I kept letting it rise to see what it will do. The critical shut down is set at 85C and once it read that temp, it did the critical shutdown. I quickly restarted and temps back to norm. Im not sure if it is mercury or some other liquid or not, but it kinda makes sense to me. but I dont really know for sure. Oh, btw, I only noticed the cpu temp increaseing, the system and GPU temps remained fairly constant. Although the GPU actually drop a degree, probably due to better air flow being lifted up in the air like that..
