I should have noted the gist of the link I posted above.
The member had contacted Alpha about the heatsinks and the post gives two responses from Alpha. Basically they do not recommend using either the PAL or PFH because of a problem with the clips pulling the heatsink down tight enough. New versions are coming out with new clip design.
I read Anand's new review and didn't see any mention of the problem. Don't know if he has the new version the Alpha e-mails mention are coming out.
