Lapping your CPU

[StormtrooperStu]

Does anyone still lap their CPU's ?

 

I did with my Core 2 Duo's but won't do it to my 8350 until the warranty runs out.

 

Just wondered if it was common practice still.

[Askew]

No.

no idea what that means or does

In certain communities it's still a normal but it was more of a fad that came and went.

It is using progressively finer sandpaper to achieve a mirror like finish on the CPU and the heatsink.

 

Both surfaces are then perfectly flat making for a better contact and better cooling.

basically use sandpaper, and scratch off some layers of the aluminium.

It does work though.

I think it means sanding down your CPU so then it is flat.

I know making the cpu uneven doesnt do much but doing it with sandpaper is a bit over the top for me.

Abraising the top of the IHS so that the heatsink/waterblock can lift up the CPU by forming a vacum when it is pressed on. It lets you use no thermal paste, and gives better temps.

you have to use finer and finer paper every time. ^^

I have tried it with a spare 3570k and it was a very minimal difference. It looks cool though when done.

Did you do just the cpu or heatsink as well.

 

It does look cool but only you will ever know.

Just lapped the top. Didn't play with the IHS since the temps were pretty normal on it.

[StormtrooperStu]

You are best off doing both.

No. My desktop CPU stays plenty cool and my laptop CPU doesn't have an IHS of course.

No you still you a very small amount of thermal paste.

I did it to mine just to see the difference.

I guess it's a bit like delidding just even rarer... You don't do it if you don't have massive amounts of spare time and the biggest entusiast in history
