That is almost literally what I did when I re-seated the CPU+heatsink in the 2nd board. I didn't use isopropyl alcohol, just plain white spirit. (the stuff you'd use for paintwork etc.). > I like Arctic Silver V, comes in a tiny hypodermic type squirter which > is sufficient for dozens of applications, and is a silver based paste, > a tiny little dab the size of a BB is plenty. What's a BB ? Given the size of the CPU surface (the Phenom is something like 30x30mm I think) I applied 5 very small measures as I felt unsure that a single larger amount in the middle would spread sufficiently. > Note Arctic Silver has a different installation procedure from regular > zinc oxide (white) compounds.. with the white stuff, you spread a > very thin layer evenly all over the CPU spreader plate, while with > Arctic Silver you put a little bead in the middle, and let the > heat-sink pressure spring do the spreading. What I have is "the white stuff". Maybe I do need to apply it differently. /Per Jessen, Zürich _______________________________________________ Prime mailing list [email protected] http://hogranch.com/mailman/listinfo/prime
