Hi all.
Sorry for the bad language, but I am really tired after working with this all night, and its a bit difficult to explain my story.
I am trying to build a fanless xbmc computer but have problems with overheating I think. The problems also happen in bios so it is not specific to xbmc.
I have the following hardware:
Case: HFX Micro
http://www.mcubed-store.com/catalog/prod...861f04ae69
PSU: EF14 PSU 138W
http://www.hfx.at/index.php?option=com_c...Itemid=143
Mobo: Zotac IONITX-G-E
http://www.zotacusa.com/zotac-ionitx-g-e...board.html
SSD: Intel X25-V
http://www.intel.com/design/flash/nand/v...erview.htm
Ram: 1GB Corsair XMS2 DDR2
This setup is kind of the same as Andy's in this thread, where I also had posted some problems with starting up the motherboard.

I got it working with a new psu and motherboard (after a long break from the project), but now I have overheating problems (I think at least).
With the case lid off I didn't have any problems and it ran perfectly for a lot of testing, but when the case is fully assembled and closed it shuts down without warning after some time.
After some test I decided to see the temperatures in the bios, and went on monitoring those for a while after boot. The temperatures I can see in the bios is the MCP temp and CPU temp. Just before the crash the two temperatures were 45 and 44 celsius, which shouldn't cause a crash, but it did. I tried several times with the same result - shutdown around those temps. After this all my tests were done in bios, and by test I just mean let it idle in bios while I monitor the temps and see when it crashes.
I got the same result when I took out the SSD, and have tested without SSD in from then on.
I have tried to take off the lid and put my fingers on the mobo just after crash. 3-4 seconds after none of the parts feels that hot. The hottest thing is the power supply, but it is not burning hot at all, I don't feel any discomfort putting my fingers on.
I adjusted the heating blocks and pipes a little and loosened the mobo from case because it might got a little bended when I screwed it to the case, because the holes didn't fit that well.
Now the blcoks and pipes wasn't as tight and nicely placed as before because I wanted to test before I tightened up.
Then I tried letting the comp idle again in bios, and after some time it crashed again. It took around the same time as before I loosened and adjusted the blcoks and pipes, but just before the crash the MCP temp were around 55 and CPU temp around 48. I tried this several time with same result.
I find it pretty strange that with the blocks and pipes a little worse placed, the computer takes about the same time to crash, and with higher CPU and MCP temps.
To me it doesn't look like its the CPU or GPU overheating, but what do I do now?
With the case lid off, I have tried watching 2 whole 1080 movies without a problem...
