Yeah, that's what I was talking about.  Come to think of it, I haven't seen
this since the 486 days. I always guessed it was because they were remarking
the chips, but perhaps I'm just overly suspicious.  I know I just stuck a
new ABIT BH6 motherboard in a system I'm building for someone and it's got a
heatsink that's apparently glued to a chip.  It's permanently affixed
anyhow.  I think it's over the PCI chipset.

Yeah, I'm familiar with heat sink compound, I use it on pretty much every
system I do anything with.  Good stuff!

I've never seen one like that.  All the ones I've seen attach to the little
tabs on the socket.  Where might I find one?

Thanks much,
