For the supercooling, no the heatpipe wont work, the material inside is WATER, assembled at a lower pressure than atmospheric, so it boils at a much lower temperature... but an LN like temps it will just freeze at the NB end. And if enough cold works down the pipe, it will be a condensation nightmare, you'd have to insulate the whole assembly.

Shimano...

For WC though, use copper and its a really NICE solution.... make one for the Foxconn NForce 590 board.... and if possible UPDATE the bios to include all the settings for the A64 that the ASUS Crosshair board includes.... the Foxconn board would be better than the already excellent product it is now!!!!

Also, let the boyz in the lab know, the Rictek 9715 used for the Vdimm is crapping out and drooping badly at higher Vdimm levels with "D9" ddr2.... just as it did on the DFI NF4-SLR DR boards with BH5 ram.
