fyo, re: "Anyone know if VIA's new 1GHz+ enhanced C3 processors require a fan? I'm actually considering buying one"

I haven't seen anything about Via's most recent processor wrt cooling/power. The Mini-iTx sounds interesting to build a "luggable computer" (I am not quite interested in a notebook). You might also consider something like the Shuttle SV24 Barebones system (listings on PW for $250 + $10 S/H) and reviewed here: hwextreme.com

I am interested in a system like this mostly as a network access point that is quiet, small, and movable. However, I think the performance for any rigorous task would be lacking compared to any real CPU&video card combination. My "luggable" computer is presently waiting more inspiration and a new round of fully integrated micro-ATX motherboards.

Heatsink Yes Fan No according to the article text, but the pics of the chips say something else. And these are not the 1 ghz+ - are these even the enhanced version you were thinkib of?

Cool processing

The VIA C3 has low power consumption and low heat dissipation, which is important because of the tight interior of the SV24 case. The C3 can also operate without a fan (but with a heatsink), which allows for a reduction in noise.
The C3 processor found in our mediaCube was a C3 933 MHz processor. This processor operates at 1.35V and is based on the Centaur Ezra core. This processor was originally named the Cyrix III, however, it was later renamed to C3 most likely because of Cyrix's reputation for its Performance Rating abuse.

At 933 MHz, the VIA C3 provides enough power for today's applications. The C3 processor uses a 133 MHz front side bus, has 128 KB L1 cache and 64 KB L2 cache. The processor's FPU operates at half the frequency of the processor, meaning 466 MHz. VIA markets the CPU as offering a high Winstone/watt. The CPU has the an extremely small die size as well, which helps in its claim to low power consumption.

Currently, the highest frequency C3 available is 866 MHz. However, VIA informs me that the 933 MHz variant will be available in December.

This processor was designed by Glenn Henry's Centaur team at VIA. I'm not sure whether the Cyrix design team still exists or not, although I have my doubts about that one.

The VIA C3 is based on Centaur's WinChip4 core, which was being designed when Centaur was still part of its former parent, IDT. It was to be the successor to its WinChip2A processors. Interestingly enough, its WinChip3 processor with an extra 64 KB L1 cache never made it to market.

Cyrix' long awaited Gobi/Jedi processor, an update to their aging 6x86 core, was to be released as VIA's Cyrix III. However, there were problems with ramping up the frequency, which caused the Cyrix III to be reintroduced as a Centaur-based product.
