i read about the lapping. sounds good. but im too scared to do it to my q6600. how much would some1 charge me to lap my processor and air cooler when i pick up the air cooler that is.
It is an easy process.
Window glass makes for a great flat surface to work on.
The typical CPU IHS is slightly higher near the edges, but that is all it takes. Place the CPU in the black pin protector packaging shipped with the CPU. This will offer a little mechanical protection and will keep and dirt from being deposited in the pins/grid.
Placing the CPU IHS down onto the sandpaper/emery cloth, apply very little downward pressure and move the CPU in a circular motion. Add a few drops of water just to keep the working surface wet.
The first grit size should be about 400. This part of the process is continued until the silver coating is completely removed. After only 10 or so revolutions, the high points appear on the surface of the IHS as the silver coating is removed, thereby exposing the copper below the surface coating.
Typically the first step at 400 grit takes about 20 to 30 minutes.
Then change the paper to a finer grit and repeat, 800, 1000, 1500, 2000...
Subsequent stages of finer grit are completed by examining the IHS (you will know just by looking at the IHS). When done properly each stages takes about 30-40 minutes depending on the jump in grit size. If not done properly, the next grit size will take MUCH MUCH longer.
Even at 1000, the surface of the IHS will reflect an image by tilting the IHS. The finer the grit and better the polish will reduce the angle needed to view a reflection. At 2000 you can use the IHS as a mirror.
I have some glass based polish that is 20,000 but have yet to use it.
If you're worried about messing it up, go buy a cheap 775 and practice on it. Measure the temp under load with a good OC and voltage, lap, then test for the results.
In no time at all, we'll have you applying Vdroop eliminators to your mobo
Cheers
BTW, the Zalman CNPS9500 has a finish greater than 2000 grit. It is has a very nice finish, perhaps the best on the market...
