Going back to quiet performance though, it seems you can run the EN15000 without the fan, although obviously at your own risk
The fan on the EN15000 is actually a fairly quiet 40mm unit that can be completely silenced by a Zalman fan controller (it only needs to be turned down about 1/3 to 1/2 way). My experience with the fanless VIA EPIA boards is that the heatsink can get very hot (almost too hot to touch), as can the CPU. Run fanless, CPU temps of 50Â° C (or higher) aren't unusual. The addition of even the most minimal fan cures this and sends the temps back to 40Â° C or less, with the heat sink barely warm to the touch.
Otherwise, for basic desktop applications, the review is on target. The C7 is much zippier then conventional benchmarks would suggest. The main issue for some is that there are only 2 SATA headers, but if you don't need any other cards, an SATA PCI adapter is one solution. This would make it more practical to use, say, as a file server since, at idle, it tends to draw under 30W at the outlet.
In practical terms, the C7 has the feel of an 800Mhz - 1Ghz Pentium III, but one that uses half the power.
Using the Zalman fan controller may be problematic, since turning it down too far will keep the fan from starting at all. In practical terms, the fan on the EN15000 can be silenced by even a minimally sound-proof case.
Also, I had to exchange a fanless EPIA SP800E with C3 processor because the SATA headers were defective. The replacement runs noticeably cooler, so there may be some variation in CPU heat output or the way the heatsink is installed.
With the installed 40mm fan turned down to about 2500 rpm, CPU temps on the replacement EN15000 board are now about 30Â° C. However, without additional cooling, Everest reports motherboard temps of as high as 55Â° C. The addition of a small fan blowing on the board brings this down to the sub-50Â° C range.
