Message: Subject: question regarding thermal pad By: Ryan Wong (IP: 219.90.77.*) Written on: 14-03-2005 17:36 Hi! I was installing the packaged heat sink and fan of my Pentium 4 3.2 Ghz (LGA 775) cpu awhile ago and encountered some problems getting the heat sink to lock into place on the motherboard. So, I pulled the heat sink up again and noticed that some of the thermal pad that comes with the heat sink remained on the cpu surface while most came off along with the heat sink. I again re-installed the heat sink in a different orientation and finally managed to fit it onto the mobo. I haven't turned on the computer yet. I am wondering, given this situation, is it safe to turn on the computer or will there be risks that the thermal pad was damaged and thus may risk forming some hot spots on the cpu? I read somewhere in this website that the thermal pad melts when the cpu is first powered up. Will this melting still provide me with safe conduction between the cpu and the heat sink given what had happened to the thermal pad? Any inputs or suggestions would be really appreciated. This is my fist time assembling a PC from scratch so I can use any help I can. Thanks! Sincerely, Ryan Wong rychris34@yahoo.com

Let me quote: "These pads are typically only suitable for one-time installation; if you uninstall the heatsink, e.g. in case of a CPU upgrade, the pad must be removed from the heatsink and replaced by thermal compound." Once the pad has melted an the heatsink was uninstalled afterwards, it's unlikely to form an even surface once reinstalled. So, remove the remains of the pad (scratch it off, or use rubbing alcohol), and apply a thin layer of quality thermal compound. bye, Tillmann By: LEERON296 (IP: 81.1.74.*) Written on: 20-06-2005 18:41 I HAD THE SAME PROBLEM DONT DONT USE THE THERMEL PAD YOU GOT WITH THE HEAT SINK ,GO BUY NORMALL THERMALL COMPOUND AND POT A VERY THIN LAYER,THE BEST YOU CAN BUY IS ARTIC SILVER AND IT NOT EXPSENSIVE AT ALL
