I wish I could get my hands on the Becooling bastids that sold me that thing. First, I ordered the mica shim but got the steel one, and once I got the steel one (damn me for not inspecting it closer) it had sharp edges on all of the interior cuts. It hacked 1/3 of the way through the card inboard of the L1 and L10 (?) bridges when I tightened down my water block.
