would like to passivly cool a socket 479 ,thinking heatpipe no fan
looking at the shuttle I.C.E. heatpipe and others.should I invest in heatsink for the southbridge chip?
found a nice board and cpu no intel numbers says confidential on board
not FCC approved
has a socket 479 1.8 ghz 2mb cache cpu 855gme chipset and a 6300esb southbridge
problem is no retention and heatsink /fan on cpu
not familiar with this type of processor.

Socket 479? I know of 478, but not 479. There must be some sort of typo.

yep socket 479 no typo
there are bout 4 MB manufacturer's that are making them
asus has a adapter 479 for 478 boards
my board is full ATX
855gme chipset 6300 i/o southbridge
all kinds of addon's
overclockable I should be able to run 1.8 at 2.2 with the right cooling

A southbridge cooler is probably not necessary with today's reduced chipset voltages.
For the northbridge, look at Zalman's ZM-NB32J passive heatsink (or different model, depending on chipsize).

It depends. As Southbridge chips tend pack more & more features (Lan, Sound, 1394, USB, WiFi, etc.), they're starting to heat up quite a lot. The latest Intel chipsets have a heatsink on both the north & south bridges.

nVidia with its single "chip" chipset since the nForce 3 needs at least passive cooling for the chip to stay alive, at least with the AMD version. The Intel nForce has a traditional 2-chip chipset (north & south).

As for cooling the Pentium-M passively, they've done so HERE (http://www.gamepc.com/labs/view_content.asp?id=dothandesktop&page=7) but needed quite a high-end heatsink to do so.

Still looking,
will test without southbridge HS ,but will monitor this close as I develope board
setups ,config.
guess'n should not be so pickly bout the cpu cooler
that zalman may work ,but I don't like the temps that where recorded as this is, going (I hope) into, small box.
If anyone is interested in pics ,I can take some and post url here.
