We were hoping for one rectangular one to cover both chips at the same time. > > Either way I think it would be best if the heatsinks were push pin > mounted, with holes in the standard positions allowing for the user to > upgrade as necessary.

Just sorta guidelines to get close to. There are maxima and minima, which can be computed by considering PCI specs and the sizes of the two chips plus routing room between them. If some people were to get the specs on the chips, we could then come up with some ranges that others could use in their search for what's necessary. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
