How hot should a fanless VIA EPIA CN10000 board in fanless case get?

Try a slim 8cm fan (1cm height)

Or alternatively, find a piece of metal so that it touch both the heatsink and the case and conduct the heat. Let the case become the heatsink

Thanks for the ideas, I think it would be pretty hard to get a good connection with the all the cooler fins. replacing the whole thing with a solid block which was attached to the case would be a good idea but a bit beyond me.

I looked for slim fans, didn't realise any existsed, but it looks like they're few & far between, the one which seems to be easily available is the zalman ZM-OP1 which is designed to work with their graphics card cooler. If I could find one which was temperature sensitive like the Arctics I'd definitely go for it but I really like the way the Arctics spin lazily when things are pretyy cool and then speed up as they need to.

So it turns out that there is some temperature monitoring on the board after all. In spite of the lack of any mention in any documentation I installed Speedfan to see if it found anything..and it did.

It found 7 possible sensors of which 3 seem to be working. The mex temps I've encountered under load testing are 42,70 and 79 celsius, at the same time my probe in the cooling fins was reporting 56.2 celsius. Pretty high temps but everything seemed completely stable.

Thanks Joshwa, where were you measuring the temp? Was it a built-in CPU thing or did you have a proble somewhere?

I used MBM5 - but the readings weren't right and needed altering. I'm surprised that it doesn't show you the CPU temp in the BIOS in PC Health Status?
