I'm planning on replacing some coolers here in the very near future, and will prob go ahead and do some lap work while I've got things apart, but I'm wondering . . . what is the best way to remove a heatsink that has thermal paste applied to it? Not like thermal grease, but the harder stuff that holds the hsink in place like epoxy would . . . Also, do thermal pads seperate from the PCB easy, or might the use of a plastic card to gently pry them up be in order? Really sorry to be asking questions that I know have been flung around the net left and right, but damn if the tech industry hasn't changed a ton since I was last getting into the nitty-gritty with hardware years ago . . .
