Help my 1.2G AMD TB

[starsss]

My 1.2G amd tb with ASUS Mobo, the temp is 65C all time. It is retail box AMD cpu. I just changed heat paste to Arctic Silver II. However, the temper increase from 60C to 65C now. What can I do for it? I want polish the bottom of my heat sink. Could you please tell me what kind of sandpaper I should use and where I can get it? BTW, how can I wipe the Arctic Silver II from the cpu and heat sink and then apply new one on it? Hope it could help.

Are you sure you attached the HSF back on properly?

You did clean off all the old thermal paste before putting on the Arctic Silver II right?

Is your probe in the way? Is it keeping the HSF from sitting on the core properly (or are you using the socket probe?)

What heatsink are you using?

Think about all these things first, then proceed.

Okay, if you really want to lap your heatsink, this is what I do...Find a flat surface like a big piece of glass or something, or a FLAT table. Tape down a piece of 320Grit wet/dry sandpaper. Use some water on the sandpaper and then set your heatsink down and begin moving it in circles. Try to make sure you keep the heatsink level. Then once the bottom surface looks even and smooth (swirl marks all around the bottom) and you can use a straight edge and see that the surface is flat, move on to 600grit wet/dry. Continue on in this manner for as long as you want. After 600, the surface should be quite smooth, though still with some sanding marks on the bottom, but they shouldn't be very noticeable. The final touch would be 1000grit sandpaper to get it really smooth, although some would argue that this isn't necessary. I don't think it is.

To get off Arctic Silver, I've found that liquid dishwashing detergent applied with a Q-tip works wonders. Then follow up with 70% isopropyl alcohol to get all the residual off. Be liberal in the usage of alcohol. But be sure to let it dry before putting anything back together. Remember to add just the minimum amount of Arctic Silver necessary to cover the core of the chip. The goal is to get as thin a layer as possible.

But, before you begin make sure everything I mentioned first is okay. Because if the heatsink/fan you have sucks or it's not attached properly, nothing you do will make the temp go down very much.

i know boards like the msi k7t turbo the thermal diode sits closer to the cpu than other boards like the iwill kk266. when running the k7t temps would hang around 59C, the same cpu in kk266 would idle around 42. is it probe movable on that board.
