Do those heatpipe heatsinks work if the motherboard is mounted vertically?

Funny you should ask that, I remembered a Dan's Data column on that recently:

My personal opinion of heat pipe products is that they are significantly less efficient than a direct-mounted heat sink, and are frequently more trouble than they're worth, except in certain places where a real heatsink is impossible logistically.
