Yeah, but from what I have heard, the Zalman can have any 80mm fan connected to it, not just the silent POS they have as an option. That means an 80mm Tornado if the user can handle the noise--so it's not just a passive cooler for someone looking to quiet their high performance computer, but potentially an overclock beast.
As for that shim stuff, you're right, it needs to be removed or else the Zalman won't do sh!t.
Damn Rambus.
