I built a fanless system with the following components:
Streacom FC8 fanless chassis
Intel DH67CFB3 motherboard
Intel Core i7 3770S Processor 3.1 GHz
Crucial 2 x 8 GB 240-pin DIMM
Intel 520 Series 180 GB SSD
slim Blu-ray player
It boots in six seconds, logs in in three seconds, and is completely silent (except for the optical drive of course).
But it has two problems (that may or may not be related):
1) The PCH is running hot, much hotter than anything else monitored by Intel's utility (processor ~38 C, PCH > 78 C).
2) Home Designer Pro, a graphics-and-CPU-intensive application, tends to crash the machine.
When it crashes, it leaves no trace. The only thing in the logs is a Critical for lost kernel power and an Error for unexpected shutdown, which together tell me nothing I don't already know--the system crashed for some unknown reason. There are no other events.
The crash doesn't give me a BSOD. It gives me a black screen, and the system then proceeds to boot from BIOS and come back up into Windows.
It seems to crash more as the PCH heats up, but that could be my imagination.
It also crashed a couple of times doing copy/paste into Paint (ironically, to take pictures of the heat sensors). This happened when the PCH was close to yellow in the monitor, but again that's not definitive.
I ran across this on a different forum: "The Intel DH67CF-B3 is an excellent motherboard but it only has one tiny heatsink, so you need to replace that if you want it to stay cool under load in a case without fans."
If that was in reference to the heatsink on the PCH, does anyone know where to get a better heatsink? The FC8 has grooves available in the heat blocks to run more heat pipes, so I could run one or more heat pipes from the PCH to cool it, if there is a heatsink for the PCH that is designed for heat pipes.
