It works! (After replacing the other top one) I've been in and out of it so many times thou, thermal paste is crap. Gonna give that another application and see how it does. UPDATE: CPU still running hot...but it's running. w\60% Fan it Idles at 72C.... lil hot for my taste but it seems stable so far. UPDATE2: Today it's idling at 61C, put a few more screws in it since I'm not gonna be inside it much now that it's working.
