Re: XPS 730 Overheating and Randomly Shutting Down
I'm not sure the H2C pump is the problem in my case. I used Speedfan to monitor the core tems, and just before shutdown they spiked above 100C. Normally they operate around 60-80C. During the spike I noticed the fans were not running at any kind of higher speed, and they normally fluctuate up and down. I adjusted the CPU fan speed using the nVidia control panel to 50% and the CPU temps have stayed around 60C since. No shutdowns. I asked Dell to send a new Master I/O board, since that controls the fans, and should get that tomorrow. Guess we'll see what happens then. On the other hand, if you got a message about the H2C pump failing - that is more likely to be your problem than the Master I/O. I have had other problems since day 1 with this machine coming back from Sleep, (huge delays in keyboard and mouse response) and they have never resolved those. Perhaps they are also related to the I/O board.
