That is a potential issue I think as well.  I have noticed, however, that you can still remove LP after a day or two.  So if you don't see the gains you like, you can always fall back to a regular paste.

Ironically, my board is now running fine (minus a die) using some CoolerMaster paste that came with a CPU cooler I had.  I think that some of the issues people may be having are application related?  Go get some chopsticks, cut them down to about 3" and sharpen one end.  Stick them in the holding screw holes (they will screw slightly in) and use them as guides.  Or ... go get some longish m3 screws.  Make sure not to apply too much TIM.  I also have a hunch that the screws do not necessarily need to get torqued all the way down.  Tightish, yes, but perhaps not fully in.  I wonder if full torque might damage the very delicate goldstrikes, esp. if they don't sit properly flush with the surrounding metal square.
