This is a custom build that has been giving me fits. Briefly, and then more specifically later, I have the 6800k Richmond and it would idle at 70C. Subsequently, it would shut down from time to time, especially on reboot or bios. This is in an HTPC case with less than ideal airflow. While playing a game, it suddenly shut down and will not reboot. On the overheating, my assessment on the shut downs is that the max temp is 74 degrees, and during the brief reboot period, it would creep up from 70 and force shutdown. I have no real explaination for the 70C idle temp, other than bad airflow. More to come. On the failure to start, it seems the 8pin CPU plug is causing a short somehow.

Now for more detail. The installation was easy. First try it all came together and booted fine. The OS is on the SSD (Win 7). Everything seemed to be in order. Then, upon most of the update/reboots, or at least half, it would shut down, presumably to overheating (as I touched the heat sink and it was ouch hot). I installed 3 80mm fans, one in over the RAM, one out next to the CPU heatsink, and one in past that. I also changed the heatsink and fan to a
ZALMAN CNPS7000V(AL)-1-PWM 92mm FSB (Fluid Shield Bearing) Silent Pure Aluminum CPU Cooler with enhanced performance and silent operation
which was only 10 bucks and did not seem to change anything.
While running AMD overdrive's stress test, it held steady at 70C but didn't fail. Of course on reboot, it would fail to restart. Now I am new to building, but it seems that 70C is very high as an idle temp? Would I be right in assessing that at 75C it shuts off, thus the problem?
Second, more pressing issue, is the fact that it will not turn on. It failed, while playing, presumably to heat, and now will not restart. I thought it to be the power supply, but I tried a few things to eliminate that (I think). On a paperclip test, it turned on a fan. So one at a time I test. The 24pin will start up the CPU fan. The 24pin + molex will start two fans. The 24 pin, molex, and sata will start the Bluray, 2 fans. Finally, will all extras on, I turn off power and now try the 8 pin cpu power. Nothing! Nothing works at this point. Am I right in assessing there is a short in the motherboard of some kind, causing nothing to fire up with this 8 pin (or 4+4 if you will) connected?
Or could it be something else. I would appriciate feedback on both the high temps and the short.
Thanks!!
